The cost is not MUCH more than the strain-gauge sensor, but its safety is quite a bit better. The agility and recharge interval were more balanced for the piezoelectric sensor. Payload, agility, and recharge interval were all about equal to me, but I preferred sensors and batteries that did not lack too much in any of these areas. #> 66 I agree.

There was no "obvious" best choice. #> 341 The graphs indicated the properties of all the different options and made a comparable visual illustration to make an informed decision on which combination to use. #> 342 The graphs detailed what aspects of power sources and control sensors are important--namely, the numerical data. #> 343 I suggested using cadmium batteries with piezoelectric sensors, together they make a strong combination of payload and agility while keeping costs in a moderate range and having strong battery life. #> 344 It became apparent to me that Nickel Cadmium batteries are superior to the other choices in most ways--they have the lowest cost and best agility and payload, and an average RPN and recharge interval. (PFC has a longer recharge interval and lower RPN but is expensive and has worse physical capabilities.) In other words, three of its qualities were superior to the other power sources' and two were average, giving it an overall above-average rating. #> 345 I agree but would like to look into the ecological impact of Nickel Cadmium. The resources stated that Cadmium is a highly toxic metal and can be dangerous. #> 346 I chose to prioritize Payload and Safety when it came to control sensors, and I chose the Lithium Polymer battery over the Nickel Cadmium because of the ecological impact that Connor mentioned #> 347 Agility and safety were attributes I found most important. The users of the exoskeletons shouldn't have to worry about things breaking down or the exoskeleton not responding when they are on a first respond team. #> 348 I somewhat prioritized physical capabilities (payload and agility), although I mostly just evaluated each of the five qualities equally. #> 349 I believed that agility and recharge interval are very important attributes when in a disaster-rescue situation. The exoskeleton must be agile in order to ensure safety of the operator and having a good recharge interval will help the rescuer spend more time in the field. #> 350 @Margaret: That is a very good point, that the RescuShell is meant to protect the user from injury and should therefore be free of most internal dangers. #> 351 It would not look very good for Rescutek if our operators themselves get injured, so we should make protecting the operator a top priority. #> 352 That was my thought exactly. #> 353 I suggest we begin design procedures on a prototype. #> 354 I would assign us to come to a group conclusion of a combination of control sensor and power source to test or prototype in some way. #> 355 If there are parts of the RescuShell that have yet to be considered, though, I think it would be good to research those too. #> 356 @Jordan I agree #> 357 Similar to what Jordan said, I think that we should do more research. We could learn more about the materials of our exoskeleton, or perhaps the actuators and how the sensors send the signals to the computer to the actuators. Maybe read up on different types of actuators similar to what was done with the batteries and sensors? #> 358 We can look into what makes the power sources and control sensors work and see if we can improve their designs or modify them so that they work better with our exoskeleton. #> 359 @Connor: Can the power sources and control sensors be modified? #> 360 If the power sources and control sensors can be modified, then the possibilities for our design are more plentiful #> 361 I think we're about ready to finish. #> 362 We could conduct research and find out. But I'm pretty it isn't possible since each power source and control sensor each have completely different systems. #> 363 Agreed. #> 364 I agree, good meeting everyone! #> 365 This is a really lame question, but how do I make the chat bar small again, now that we're done with the meeting? #> 366 @Nassim Tehrani: Thanks. (I had no idea you had control over that.) #> 367 @Nassim Tehrani: Is there any way to edit a Notebook after saving it? Sometimes I forget to put the correct time before saving it, and then there is no edit button--only "Submit" and "New Notebook", so I submit an additional Notebook with the correct tim #> 368 @Nassim Tehrani: Is there any way to edit a Notebook after saving it? Sometimes I forget to put the correct time before saving it, and then there is no edit button--only "Submit" and "New Notebook", so I submit an additional Notebook with the correct tim #> 369 @Nassim Tehrani: Is there any way to edit a Notebook after saving it? Sometimes I forget to put the correct time before saving it, and then there is no edit button--only "Submit" and "New Notebook", so I submit an additional Notebook with the correct tim #> 370 (And sorry, I have no idea why it submitted that message three times!) #> 371 @Nassim Tehrani: So would you recommend not submitting the incorrect one, copying and pasting it into a new one, fixing it, and submitting only that new one? #> 372 Good morning, everybody. #> 373 Are we each going to research the same consultant? #> 374 Okay. I will do my research based on the requests of Meredith Yamasaki-Nolan. #> 375 So we're basically making the notebook on how well the hydraulic actuator fits the desires of each consultant? (But each team member does only one consultant)? #> 376 @Jordan: Yes #> 377 I will evaluate hydraulic based on the desires of DaShawn Edwards. #> 378 @Jordan: And explain how the attributes the consultant is concerned about (i.e. payload, agility, etc) changes or is effected by different things. #> 379 Okay, I will look into Benjamin Taylor's requests. #> 380 I will look into Paulo Henriquez's requests #> 381 I will look into Laura Rivers' requests then #> 382 Should the 5 prototype REDDs be made into a Batch? #> 383 @Nassim Tehrani: Good morning. #> 384 Are REDDs shareable in any way or does each of us create the team batch individually? #> 385 Ah, now they are all shared! #> 386 Well we can attach other people's batches into our own notebooks #> 387 Previous to about 3 minutes ago I was only able to view my own prototypes, but now they are all available to me. #> 388 There are five members of our team, so I think it might be a good idea to first try to explain the top two (subjectively) most important designs to each other, and narrow down the options from there, revising if necessary. Does this sound good to everyone else? #> 389 Yeah, that's good #> 390 I like that idea #> 391 @Nassim Tehrani: Are we to just describe our prototypes in the discussion? #> 392 My two most "important" prototypes are my prototypes titled "Prototype 5 Low-ROM (high recharge interval) variant of 1" and "Prototype 1". I have several other prototypes built to test maximum abilities in one area, but I believe these two prototypes will be more applicable to all the of the consultants' desires, since they are somewhat "balanced". They do emphasize the qualities DaShawn Edwards was looking for (agility and low RPN) more than other qualities, but I do not think the emphasis is too great to exclude the other consultants' requests. #> 393 After viewing the results of my prototypes, my top two are my "Highest Agility" one and "REDD 6" one. Highest agility uses Aluminum alloy, NiCd battery, Hydraulic actuator, strain gauge sensor, Rom 6. REDD 6 uses Steel, NiCd battery, Hydraulic actuator, Piezoelectric sensor, and Rom 5. #> 394 Prototype 1: I chose NiCd for high agility and average RPN, ROM 4 for decent agility (but not too expensive or power-consuming), aluminum for the light weight and low cost, and piezoelectric control sensors for average agility but low RPN. #> 395 Prototype 5: It has ROM 3 instead of ROM 4, but is otherwise the same as my first prototype--there were significant reported differences between the two, so I figured it would be interesting to see the difference in the context of the full exoskeleton. #> 396 My prototypes are also balanced to try to meet other consultants requests #> 397 @Margaret: Some of the parts, such as power source and control sensor, are easy to determine reasons for choosing since their technical specifications are, well, specified. Could you explain why you chose the materials and specific ROMs that you did? #> 398 I believe that lighter materials will put less strain on the system, thereby increasing recharge interval, agility and safety. For this reason I think Aluminum or Composite material should be used #> 399 The two prototypes that the consultant that I chose to focus on are "Maximum Safety" and "Safety + Payload". My consultant was mainly focused on safety of the product and would want to have that be maximized. The "Maximum Safety" prototype has the lowest RPN value and the Composite material is strong while also being lightweight. The "Safety + Payload" prototype has the NiCd power supply which supports a little bit more payload. #> 400 Did anybody else get a "502 Bad Gateway" error page? #> 401 Likewise, are we all back now? #> 402 Sorry, my computer just exploded and said there was a bad gateway #> 403 @Connor: I had typed out "Those are some interesting points," but I didn't get to send it before the crash. #> 404 Hmm I am experiencing a lack of an email-notebook-worklog-resources-etc window... #> 405 "Highest Agility prototype"- aluminum because it is lightweight so the exoskeleton and person inside won't be weighed down, and rom 6 because agility improves with the addition of active joints. 6 has the most active joints #> 406 I too have no window for email and whatnot #> 407 I also have the same problem #> 408 "Redd 6" prototype- steel because it is durable and I wanted to see how it affected the performance of the exoskeleton and rom 5 because I had been using 6 for the rest. #> 409 @Jimmy: Your Maximum Safety and Safety + Payload prototypes looked like they performed very well, but were expensive, my consultant was interested in keeping prices low so the product would be more marketable #> 410 We can't get to our notebooks. #> 411 @Jimmy: What was your reasoning for putting piezoelectric on each of your prototypes? #> 412 I would also be interested in sharing the problems (or non-problems) the hydraulic actuator had for each consultant's specifications. For DaShawn Edwards, hydraulic's main issue was its agility, so I tried to choose other components to be agile. #> 413 @Jordan: Piezoelectric seemed like the best sensors to use regarding agility, however, they were also the most expensive #> 414 @Team: Does 5:00 PM sound like a good group deadline for choosing which 5 prototypes to test? #> 415 @Jordan: As long as the website starts working #> 416 PIezoelectric control sensors had the lowest RPN Values #> 417 @Nassim Tehrani: My workspace still is not running, the chat is still expanded like it was during our meeting #> 418 I'm good for 5. But my workspace still isn't working. #> 419 Soooo...it's still not working. #> 420 @Margaret: The chat is still expanded, but refreshing the page (while logged in) loads the workspace window for me. I am using Chrome. #> 421 Has everybody chosen a few that they think are the best prototypes? #> 422 Interesting... I'm not sure if that was supposed to happen, but there are now View Results buttons by each of the batches except for the team batch. They display technical specifications of each prototype. #> 423 The results for the team batch are up. The numbers look good. #> 424 @Nassim Tehrani: Good morning. #> 425 Good morning. #> 426 Okay. #> 427 I am ready. #> 428 I am ready too #> 429 I am also ready. #> 430 Because the meeting was cut short with technical difficulties, we all proposed two prototypes to be submitted for testing. There was a great deal of overlap in recommendations, and it was easily cut down to 5 designs. #> 431 We each had our individual reasons, but I chose mine because they seemed balanced and able to fit quite a few requirements. #> 432 Although we had some technical difficulties, we were able to propose our designs and agree upon them #> 433 These 5 prototypes were mostly fit into the internal consultants. I reviewed their preferences and chose two that fit those preferences the best. #> 434 I attempted to meet the needs of my internal consultant by suggesting designs that were cost-efficient #> 435 I did not look at only the two qualities dictated by the internal consultant I reviewed, but rather all five qualities. I slightly prioritized agility, since DaShawn Edwards had high agility recommendations and the hydraulic actuator was inagile. #> 436 I had prioritized agility over payload and chose light materials because I believe the rescue workers would like something comfortable to wear #> 437 The rescue worker will be most concerned with safety and payload. He/she would need sufficient lifting capacity to get the job done, but cannot be worried about the product malfunctioning and thus ending in a bad situation #> 438 And cost would only affect the company, not the worker. #> 439 I believe that the two qualities most affecting the rescue workers would be agility and payload (the physical qualities). Risk priority probably would not have a day-to-day impact. Recharge interval may become irritating if too low, but I think it should be possible to use another battery or simply get it recharged. #> 440 I was reviewing Paulo Henriquez's requests and he was most focused on safety. So I prioritized safety and then balanced the other factors. ] #> 441 I valued agility over RPN because I personally feel that in a dangerous setting the agility of a suit to move out of the way of a hazard would be rather important. I mostly did not try to maximize any one attribute but rather look at overall "good" numbers on the components I used in my prototypes. #> 442 I agree with Jordan, and since hydraulic actuators had the greatest payload ratings, but low agility, I did not give much though to payload, but focused on maximizing other attributes, mainly agility. #> 443 That's a good point ^ #> 444 That sounds accurate. #> 445 Thanks, you too! #> 446 @Nassim Tehrani: What is on our schedule for today? #> 447 @Nassim Tehrani: what stage of the process is considered caught up? #> 448 @Nassim Tehrani: are we to work together on the final project? #> 449 presentation* #> 450 The project is to be presented after the work with reassigned teams is completed, correct? #> 451 @Nassim Tehrani: So we are doing individual presentations at the end of the second set #> 452 So we are not presenting on Rescu-Tek? #> 453 Yes we are, we're just going to a different team e.g. Hydraulic, Electric #> 454 Oh gotcha #> 455 @Justin Kim: I am simply testing this chat feature to see how it works. Does it? #> 456 @Justin Kim: I'm Tiffany. #> 457 @Justin Kim: Hi my name is Amelia #> 458 @Justin Kim: My name's Devin. #> 459 @Justin Kim: good morning! just checking in about what our task for today is? #> 460 I'm unsure whether or not my worklog was submitted. How do I track previous worklogs? #> 461 I believe that I have submitted all of my notebook entries. #> 462 Ah, I clicked the save button rather than submit. It should be available for witnessing now. #> 463 I also did that, but I think that I corrected it #> 464 @Justin Kim: Im not exactly sure what I am supposed to do. I have submitted both my staff page and my interview and I have not gotten further feedback on my next task. #> 465 @Luis: I don't know how to. I click on the worklog page and it only shows a blank page #> 466 ok I submitted a second one just to make sure #> 467 Hi what are the instructions for the meeting? #> 468 I'm confused on how to enter values for graphing. I was only given values for cost and safety...what about the other factors? #> 469 Im almost on the graphing. #> 470 hey team, so what I'm gathering is that we are being encouraged to talk about the graphs #> 471 Safe to assume this meeting is 100% online? You'll just be asking questions? #> 472 would it be the Nickel Cadmium Battery? #> 473 based on the Cost per battery/risk priority? #> 474 If it's cost per battery/risk, then the Nickel would be the best choice #> 475 But, seeing as it should be safety as the main priority, I think the Hydrogen would be the best. It creates less harm to the environment as well. The only drawback would be the price but I personally would choose safety and effectiveness over cost. #> 476 The lithium polymer battery can be compared to the nickel cadmium battery but at the same time it is more safe at reasonable cost. #> 477 Lithium polymer batteries are also lightweight and retain high energy density. #> 478 @Justin Kim: With the exception of those not assigned said activity? #> 479 @Justin Kim: How do the numbers given in the technical documents relate to safety? Are we shooting for high or low numbers as far as safety goes? #> 480 @Justin Kim: I am having trouble with writing a syntheses expressing my choice of power source and control sensor. What should I include in my syntheses to make it strong and clear? #> 481 @Justin Kim: Will we be having our group meeting today? #> 482 None here #> 483 To what extent should we go with our research? How do we know we have enough information for a successful presentation? #> 484 Oh, workflow questions...sorry I'm ahead of myself... #> 485 @Justin Kim: are you referring specifically to the due dates or just the process of the work that we're supposed to do? #> 486 For our task today what is ROM and Material specifically asking us to do? #> 487 I haven't recieved my task for today yet...I've completed all worklogs and notebook entries. #> 488 What will we be discussing today? #> 489 The graphs indicated the advantages and disadvantages of each power source and control sensor. #> 490 The graphs enabled us to compare power sources and control sensors given their strengths and weaknesses in relation to the five main attributes. #> 491 The NiCd out preformed the other power sources in 3/5 aspects #> 492 It was obvious that one power source and control were obviously the best choice...but then they both faltered in the area of of cost. #> 493 The Strain-Gauge and the Piezoelectric both preformed will in payload but they were more proficient in agility and safety respectively. #> 494 I choose safety and durability over everything else. You want to be able to be dependable if you want to move forward as a company. #> 495 I wouldn't say "obvious" because we did have to ration on which attributes were most important, and the component that strongly upheld most of the five attributes....I ended up going with the NiCd power source and the Strain-Gauge sensor. #> 496 I thought that the payload aspect was paramount so thats what guided me to the NiCd battery #> 497 I prioritized cost, safety, and agility when choosing a power source and control sensor. #> 498 The graphs projected the supposed aspects of the battery power and use through the tests done. We could see and pick out each individual batteries strength and weakness through this. I picked the battery that had the best outlook throughout all of the tests. #> 499 With the graphs I could easily draw conclusions about each type of component given their areas of strengths and weakness. #> 500 @Amalia: Agreed! #> 501 come up with a common aspect that we think makes one power source the particular choice? #> 502 I believe that further research should be conducted and a final selection of the power source and control sensor should be made... #> 503 Select a final battery and sensor to fulfill the requirements of rescue-tek's philosophy in terms of building an exoskeleton. #> 504 @Amalia: yes because there must be a preliminary outline for the qualities of a product #> 505 Final selection of a power source and control sensor #> 506 Correct #> 507 Yes #> 508 did you main notebook? #> 509 do you assign the new work long? #> 510 worklog* #> 511 Did you mean notebook? #> 512 I received my assignment really late, and had prior commitments to which I just found out about the task. Is it alright if I submit it by tonight? #> 513 @Amalia: I received my assignment really late as well. #> 514 Okay, good (in a sense). #> 515 I just panicked because the deadline was that night or by 9am the next morning and I haven't checked the email until I got back later in the day... #> 516 Same thing happened with me. Hopefully my assignment gets reviewed... #> 517 there will be another team meeting today? #> 518 I'm finishing up my worklog now. #> 519 I am too #> 520 worklog for which assignment? #> 521 A worklog must be submitted evaluating your research on the internal consultants #> 522 I made a notebook for the internal consultants but now I cant seem to find it and consequently make a worklog #> 523 i just submitted my work log. Now onto the Assessment request #> 524 ok #> 525 ok #> 526 ok #> 527 alright, and that is based off of the internal consultants requests? #> 528 Will I be able to learn more about the "PAM" actuator from the link in the email from Vendant? #> 529 Alright, sounds good #> 530 I would Like marketing and sales please #> 531 I #> 532 I will focus on quality #> 533 ok- with that being said I would like to look at DaShawn with bio med and risk #> 534 Oh, sorry, Meredith Yamasaki-Nolan #> 535 and then I look specifically at DaShawn #> 536 Oh, Paulo Henriquez\\ #> 537 so is that all @justin? #> 538 will we be receiving an email regarding our next assignment? #> 539 (the design of the prototypes?) #> 540 I thought I just submitted my recap of the the meeting #> 541 you would like me to re write what I have written because it it not in depth enough or you simply have not received it? #> 542 sorry I'm confused because I submitted it 13 minutes ago #> 543 I resubmitted #> 544 is this required for right now? or is it acceptable for me to work on this on my own? (have to go to class) #> 545 By citing sources, we are just citing the specific technical document being referred to, right? #> 546 Ok, great #> 547 I'm unable to submit notebooks, however they are saved. #> 548 I reviewed and witnessed your notebook entry. Your research and recommendations will be invaluable as we move forward with the design process. #> 549 This is what Vedant sent me. Did I do something wrong? Should I go back and do more research so that it is "valuable #> 550 Maybe he just wants you to revise.....I'm not really sure though #> 551 Maybe he just wants you to revise.....I'm not really sure though #> 552 You're further than I am. My notebooks entries won't even submit... #> 553 Tiffany, your work was perfectly fine. "Invaluable" was a compliment. #> 554 I mean Amalia, not Tiffany. Excuse me. #> 555 Thanks! I was very worried! #> 556 @Amalia: I'm confused. Are we supposed to just do the REDD's or make batches for each design? #> 557 I don't think we do batches yet... #> 558 @Tiffany: Use REDD to design 5 types for our actuator which is the PAM #> 559 I know that, but what about the batch option? #> 560 Do we create batches after we create our designs? #> 561 Good morning! #> 562 good morning everyone #> 563 @Amelia: Good Morning :) #> 564 @Justin Kim: I have not been updated on the latest notebook/worklog entry... #> 565 @Justin Kim: Morning! I have not received a next task yet. #> 566 @Justin Kim: I submitted my worklog and it was signed #> 567 ok I received an email #> 568 So shall we begin our discussion of our prototype choices? #> 569 @Justin Kim: Yeah I got it! #> 570 So should we start off by each of saying what their first choice based on their 5 prototypes are? #> 571 Same here. #> 572 Well I can only see Tiffany's and mine. #> 573 I can only see Amalia and my own prototype designs... #> 574 I was not prompted to create a design #> 575 So do we still decide on which 5 to submit? Since it's only two of us is that still possible or valid? #> 576 Would it be appropriate to derive our design choice from only one other team member's designs? #> 577 Okay I see Amelia's now too... #> 578 But Tiffany, what were your top 3? #> 579 We pretty much had the same designs- PFC and NiCD were our favorites as well as Aluminum and composite materials. #> 580 Your 4th design, my 4th design, and Amelia's 2nd design. Yeah, ours are pretty similar... #> 581 We also use ROM 3 and 4 #> 582 Okay. Out of those three, I think my top is Your 4th Design, Amelia's 2nd, and my 4th. #> 583 So we just need two more then. #> 584 Yeah I agree, those seem best #> 585 sure, so as 4th? #> 586 Maybe we could include Tiffany's fifth design because I also have one similar #> 587 @Amalia: Your 5th design, it's pretty much the same, just composite instead of aluminum #> 588 Yeah-then we're looking for one more #> 589 @Amalia: Your 4th and my 5th would interesting because they use the same components, just slightly different materials. #> 590 okay, so then tiffany's as 4th and mine as 5th. Is that okay? #> 591 Is everyone back on? #> 592 I can only access the chat archive right now... #> 593 Ok I'm back in business #> 594 hi ok i couldn't log in.. so to clarify- we'll be looking at Amalia's 4th and 5th designs, Tiffany's 4th and 5th designs and my (amelia's) 2nd design?? #> 595 @Amelia: Yes #> 596 Ok thanks!! @Tiffany #> 597 @Amalia: Do you agree with Amelia? Those designs are correct right? #> 598 I created the batch #> 599 Let me know if you guys have trouble accessing the batch. #> 600 @Justin Kim: Thanks, see you Thursday! #> 601 We need another design to test. My 4th design and Amalia's 5th design are exactly the same. I'm sorry I overlooked that. I assumed that she used Aluminum instead of composite material. Shall we test Amalia's 3rd design? That's the one I was shooting for #> 602 I will also update the batch ! #> 603 But then again, Amelia's 2nd design is the exact same as my 5th design... #> 604 It's almost as if we cannot come up with the perfect 5 without a repeat Lol #> 605 Hi, sorry just got back on after that problem my connection just wouldn't work. #> 606 for the last one let's do Amelia's 5th design. It's different. #> 607 Amelia's 5th design #> 608 Sure #> 609 Shoud I make a new batch though? The results have already come back.... #> 610 I'll make a new batch but I don't know if they will test it... #> 611 Good morning everyone. #> 612 Good morning #> 613 Good Morning! #> 614 Hi! #> 615 Sounds good! #> 616 ok present for meeting #> 617 present #> 618 Present. #> 619 Present :) #> 620 ok #> 621 Ok #> 622 We chose the ones that us three had in common and then choose the last two based on differences with the ones we already had. #> 623 Initially, it was not difficult because we found that most of our designs were similar in use of materials, control sensors and power sources. But we ended up going with the designs who's aspects satisfied those of the internal consultants, preferably succeeding in 3/5 areas of the five attributes. #> 624 they serve as the best group to test so we can closely analyze the prototypes variables #> 625 I personally thought they had the best mix of material, sensor control, battery, and ROM through the information and test results given to us. #> 626 We considered the anticipated payload, agility, cost, priority risk number and recharge interval proposed by each internal consultant. #> 627 We had to think harder and interpret on whether or not the prototype and materials would work and if they would be the best choice in each consultant's preferred aspects and to how much could they fulfill those needs. #> 628 We then tried our best to factor those into our prototype designs. #> 629 I used the materials and design elements that worked best with my internal consultants requests #> 630 Yes! You had to or else you really didn't know what you wanted within the prototypes #> 631 In terms of a minimal basis given that the internal consultants pushed for higher restrictions on the designs... #> 632 I think safety, payload, and agility #> 633 I think safety, payload, and agility #> 634 I chose to consider safety, payload and agility most, but all five attributes are imoprtant #> 635 I agree, specifically with agility #> 636 With my designs, safety was always a factor #> 637 important* #> 638 I concluded that the worker's overall safety was more important than cost if anything. #> 639 I addressed safety by thinking if I myself would feel safe with this type of sensor, this type of battery etc. #> 640 yes I believe so #> 641 The suits efficiency was also important, because what's a rescue suit with poor performance? #> 642 because with the prototype design process showed us how all the elements work together #> 643 Yes, but lots of room for improvement #> 644 Yes, but there is room for improvement. #> 645 Our designs performed well in 3/5 areas but I didn't find it impossible to meet the internal consultant's criteria. Though, it will be difficult to come up with the perfect design. #> 646 I didn't think they would really affect each other as much as they do now. #> 647 Each element could make or break the design in various combinations of areas meaning that you have to come up with the perfect combinations of design elements.. #> 648 Is it possible that we could turn in certain elements of our poster by email for editing and critiquing? #> 649 Awesome, Thank you. #> 650 Is the presentation due by the next work period? #> 651 Oh okay, thanks! #> 652 Should we be working on the presentation? I havent gotten another email #> 653 okay I just got it! #> 654 @Justin Kim: Should I create a batch for the designs even though a batch has already been made? #> 655 @Justin Kim: alright sounds good #> 656 ok #> 657 Hey guys, I'm Robert. Can't wait to see what we come up with through this project! #> 658 Nassim, is there anything else we need to do right not besides the interview? #> 659 @Nassim Tehrani: Thank you! #> 660 Interview submitted at 10:27 on September 17th #> 661 Hi Nassim, I did not receive the email about creating a staff page. Could you resend it when possible? #> 662 @Nassim Tehrani: I haven't yet received an email refering to a notebook entry. If you could send this to me as well that would be great. As of yet, the only email I have received is the Entrance Interview. #> 663 I have completed the interview, but I haven't received any other additional e-mails #> 664 How would I find out what time I completed it? #> 665 I submitted a time in my notebook but I still haven't received anything #> 666 Upon completing my Notebook entries, the share button will not allow me to continue even after checking the box to its right #> 667 @Nassim Tehrani: Got it, thanks. #> 668 Hey Peter, I was having the same problem last night. I can see your entry because you shared it with us on the shared space but you also have to click the other button in order to submit it #> 669 @Nassim Tehrani: of course, I see that you're at the University of Minnesota that's about fifteen minutes from my hometown and I almost went there. #> 670 @Nassim Tehrani: Yes I will do so now #> 671 so I have submitted all notebook entries and my interview submission has yet to be witnessed. I also emailed Vedant and have not heard back. I have not received anything in regards to what I should be working on or researching. #> 672 Over the weekend I looked at Pneumatic actuators and how they differ from the other types listed in the REDD setup but otherwise I am at a loss as to what I should be specifically working on...? #> 673 My staff page has been witnessed, just resent the Interview submission #> 674 yes it is marked as witnessed at 9:37 on the 19th almost a minute after I submitted it, I will resend it #> 675 I am working on the Staff Bio work log and assume I will receive more work once it is completed #> 676 @Nassim Tehrani: I only recieved the staff page email today however I had looked around the page last week and found it on my own. Because I never received the email for the staff page assignment, I was not aware of the notebook entry after the assignment #> 677 do we simply do the meeting through this chat archive? #> 678 What do you want to hear? #> 679 I've been looking at the REDD modules we are allowed to use and it seems that we're working on only the legs or transverse plane... #> 680 I have not gotten to the graphs #> 681 I just began mine because I just received the email for the research during class today #> 682 Before we address this, where is everyone at in their research? #> 683 I was just about to do the graphs. #> 684 I am at the same place Peter is #> 685 has anyone completed the graphs? #> 686 I was about to start the graphs. #> 687 Alright, I'll take that as a no. Nassim, where do you want us in our research before this meeting continues? #> 688 I'm at that same point Peter. #> 689 Can we all agree to meet at say, 10pm tonight on this chat source to discuss the graphs that we should be able to look at by then? #> 690 the chat archive will still be viewable by then by our supervisors and then we will be caught up in regards to research, graphs and the first team meeting #> 691 I don't think they will send them until we finish the research notebook #> 692 Can't we just do the graphs real quick right now? #> 693 Does anyone know how long they take? #> 694 Some people are really behind, but I think 10pm is a fair time for everyone to get caught up. #> 695 Why don't we all do our graphs and submit a summary and explanation of them to this chat by 10PM? #> 696 If you have the graphs complete them and write your thoughts, as we finish them ourselves we will look over what other group members said and add our own opinion/criticism #> 697 we'd also have all of tomorrow, basically throw any input in when you can and we can read it in the chat archive whenever we have the time #> 698 Alright. #> 699 @Nassim Tehrani: Will that work out if we do our graphs by 10pm? #> 700 So as of know we are inputing our graph reflections as we finish by 10pm. Any objections? #> 701 *now #> 702 So to clarify we are to have our graphs completed by 10pm but our reflections are postponed? #> 703 How can I make my chat window smaller? I need to use both windows if I'm going to complete my graphs. #> 704 For the power source I found the best one would be NiCd. And I found the best one to be either the Piezoelectric or the Strain-Gauge. Both of these are based on the being the most "even" graphs. #> 705 I agree with Mitchell with the power source. NiCd offers the best all around support of the three options. I decided in my opinion that Piezoelectric was the best sensor. It offers decent middle ground agility and recharge interval but has the benefits of the highest safety rating. I think this would be worth the higher cost. #> 706 @Nassim Tehrani: I have finished the research notebook, can you witness the entry so I can work on my Work Log and graph? #> 707 I would also agree that the NiCd battery should be used. It has the highest payload and agility ratings, plus the safety is still acceptable. And it's significantly cheaper than the alternatives while the Penzioelectric control sensor isn't much more than the strain gauge while making up for any safety deficiency. #> 708 I have submitted two notebooks and received emails explaining that they were not what they had wanted and they were very unclear as to how to make it better #> 709 they mentioned that they wanted the tables to be accurate with their past research so I added the tables that we used to base our graphs yet received a second email explaining that it was still not sufficient #> 710 I could not figure out how to do that. I made them in the REDD program but found no way to put them into notebooks so in the notebook I mentioned that I had made them and to see REDD modules #> 711 @Joseph K: At the top of your notebook page when you are working on it there is a paperclip you can click on which will allow you to attach things such as your graphs. Its right next to the submit button. You can also go to your graphing tool and there #> 712 thanks #> 713 Are the team meetings conducted in the chat or as a group in class? #> 714 Ok, so what is the subject of the meeting? #> 715 I found most of you saying that the NiCd battery was the best choice #> 716 but I thought that the PFC despite being more expensive would work better for our situation #> 717 I thought the NiCd battery was the best and the Piezoelectric sensor. #> 718 I found the NiCd batteries seemed to be the best choice because they offer good all-around support in the desired fields #> 719 If you really think about it we don't need the sensors and batteries to be the absolute best all around #> 720 we are using them for search/rescue during disasters correct? #> 721 Why do you think that #> 722 @Joseph K: Why is that? I agreed with Mitchell about the Piezoelectric #> 723 I also agree with Mitchel, I think safety and performance are our greatest worries and the NiCd batteries help us do this at the lowest cost #> 724 Yes but why PFC over NiCd? #> 725 I also thought the best power source was the LiPo battery. Not only did its safety make it a top choice but in addition, it has a much high efficiency than NiCd #> 726 we can assume that we dont need a whole ton of agility as they all fail within about 40 degrees per second which is very fast....I looked up how much the payload difference is for each skeleton type and realistically even with the stronger battery we wouldnt be lifting cars #> 727 the most we can lift with the PFC (ideally) is about 450 lbs #> 728 Piezoelectric #> 729 @Peter H: I only found the LiPo batteries to be stronger in payload. #> 730 the other batteries or sensors only add so much more to this payload weight so even if we have the best payload ability we still won't be lifting cars or anything insane like that #> 731 The Lipo had the lowest safety rating out of all the batteries #> 732 What about the LiPO? #> 733 And no one power source or control sensor performed well on every attribute. They all had their strengths and weaknesses. #> 734 Piezoelectric sensors I think are the sure way to go. Agility is important for the safety of the operator when in an area which is hazardous. As for LiPo, I agree with Carl that a low safety rating is not something to be taken lightly and I believe a company or operator would be willing to pay for a much safer piece of equipment #> 735 the safety and recharge interval seemed to be the most important to me as we will need the skeletons to hold up in disaster conditions while being used as long as possible #> 736 I would also compare the outputs of LiPO and NiCd in the Standard Position Control Sensor graphs. #> 737 The NiCd performed very well from an all around standpoint, as did the piezoelectric sensor based on the graphs #> 738 Graphs helped show the strong and weak points of each battery. I chose NiCd because they are pretty average all around and are the most cost efficient. #> 739 It seems we are all in concensus about the Piezoelectric does anyone disagree with that? #> 740 I disagree with Joseph, agility would better help deal with or completely avoid hazards in a dangerous environment #> 741 I'm still sticking with the NiCd since it only has one least desirable feature and that's its battery. The other two have three least desirable features. #> 742 look at how they measured the agility, the differences between the batteries agility are very minor and only while operating under their maximum payload #> 743 I agree with Mitchell, also we need to save costs somewhere, and the NiCd battery is the cheapest #> 744 @Mitchell: That is a good way to look into the graph for the battery. #> 745 @Carl: That's exactly it if we are going with a more expensive sensor when then need a cheaper battery, while not really sacrificing quality. #> 746 @Joseph K: Even disregarding agility NiCd still maintains a better all around battery because the others have specific flaws #> 747 Does anyone disagree that the Piezoelectric sensor is the best suited #> 748 I would agree. #> 749 Are there any major objections to NiCd and Piezoelectric? #> 750 I do agree that based on the graphs the NiCd battery is the best choice for the project based on overall cost and efficiency, I think it would also be worth it to test the other batteries in the field as to get a better idea to what we will need #> 751 Yes I agree as well #> 752 Any objections to NiCd as the Battery? #> 753 I think we can all agree on Piezoelectric #> 754 Agreed with NiCd #> 755 So it seems that our final decision is the Piezoelectric combined with the NiCd? #> 756 I still do not agree with NiCd because its low efficiency will puts limits on its uses in almost all areas. #> 757 @Joseph K: No disagreements to more field testing. I'd like to see testing in poor weather conditions like heat, cold, rain, etc. #> 758 I think it would be cool to run an experiment set up to use the Piezoelectric sensor with the different batteries #> 759 I agree to test the other batteries out, but for now I say we just stick with the NiCd and Piezoelectric for now and in the future we can test the other ones. #> 760 @Peter H: How is NiCd that low efficient? #> 761 @Robert: if you do some external research on NiCd batteries you can see that they are quick to burn up and not as reliable as other batteries #> 762 Agreed #> 763 @Mitchell: Agreed #> 764 If you notice in the experiments they were all done with a standard position control sensor powered by the different batteries #> 765 They do still appear to be the best choice for now #> 766 As for reliability, Toyota has used them in the prius since its debut. #> 767 If I were Vedant I would allow us to run an experiment that allows us a prototype using a piezoelectric sensor and test how the different batteries work with it #> 768 Something similar to a field test #> 769 I would assign tasks that use the batteries and sensor in experiments. #> 770 @Nassim Tehrani: Take our selections and combine them in an exoskeleton and undergo specific testing of that combination. #> 771 I agree with Robert and specifically to use the Piezoelectric which we have already agreed on #> 772 @Nassim Tehrani: A more in depth study of the benefits of each battery that involves experimenting with each type using the piezoelectric sensor we agreed upon. #> 773 We need to do some sort of testing in the environment in which these exoskeletons will be used #> 774 I think everyone is agreed in field testing of our choices would be our next assignment. #> 775 I think we should set up two simulations, a burning building and an artic rescue. This would also allow for a heat and cold testing #> 776 If we need to do more research then I would assign articles where they show the sensors and batteries in real life things, like cars or anything else. #> 777 Yes, lets try that, we have already seen articles and data about each but in order to make an informed decision we need to see these batteries performing. #> 778 @Carl: I agree that we need to set up those different simulations and also include a control one under normal circumstances #> 779 @Robert: yes #> 780 I would like to add a rain/water element to each simulation. #> 781 is there anything else we'd need to consider? Heat, cold, water damage...? #> 782 high wind conditions #> 783 would snow or a broken watermain/firehose work? #> 784 earthquake/shaking senarios #> 785 high climbing, if they can balance on steep inclines for mountain rescue #> 786 It may also be useful to see how these batteries perform when they begin to lose output. This way, we can observe how quickly the battery loses power before dying. #> 787 Only if its currently snowing. I want to see how the elements of our design hold up against being wet. Water and electrical components haven't exactly been friends. I don't know if wind is necessary but shaking would help test agility. #> 788 So Nassim what you're saying is we should conduct outside research on our sensor and battery choices? #> 789 @Joseph K: I think that would relate more to the control sensor that the power source. #> 790 I think that would be more of a test for the mechanical shell part of the exoskeleton #> 791 @Peter: also consider the way that each battery decides to apply it's charge to the unit as a whole, if it doesn't apply enough at one time then it may be useful to the suit for a longer period of time yet unable to allow for a change in pressure necessar #> 792 or climbing #> 793 yes, ready to move on #> 794 yeah #> 795 I think so #> 796 Yes #> 797 I am ready. #> 798 I am having a problem submitting this notebook? #> 799 I do not seem to have a worklog to edit for this latest assessment. #> 800 Use the "notebook" #> 801 Nevermind, it just took a little time. #> 802 There is no submit button #> 803 alright #> 804 It says it is submitted and witnessed and I received an email confirming it #> 805 thanks it is now working #> 806 Yes, just waiting on the new email #> 807 hello team, how do we want to split up the consultants? #> 808 looks like we each get one #> 809 can we do it so that we take the corresponding one using the order listed under "Pneumatic" in the top right corner? #> 810 Don't we all have to do all of them? #> 811 Ill take biomedical #> 812 sure I'll take research and design #> 813 this would mean that Carl takes Marketing and Sales, I'd take Biomedical, Mitchell would take research/design etc? #> 814 @Mitchell : do just one #> 815 sounds good, good luck guys #> 816 oh i get it, ill be quality engineer then #> 817 I think so #> 818 @Nassim Tehrani: where do I find the actuator specifications, the company's research? It says they're available in work pro...? #> 819 Start at Resources #> 820 Ah, listed as actuator descriptions, thanks Robert #> 821 3. Based on our prior research, record in your engineering notebook the effects of each actuator (i.e., hydraulic, electric, and pneumatic) on the attributes that your internal consultant(s) care most about. As always, cite your sources. For example, if your internal consultant is concerned primarily with payload, research how it changes as the materials, range of motion, control sensors and power supplies change when using Pneumatic as the actuator. #> 822 @Nassim Tehrani: to be clear, we should only be analyzing the effects on the Pneumatic system? or does it want us to compare them as well #> 823 it is unclear in the email #> 824 @Nassim Tehrani: Is that the notebook and work log about our team meeting? If so it says my work log was submitted and witnessed but my notebook was only submitted and has not been witnessed yet. #> 825 Nevermind I think I get it. #> 826 Alright, thank you. #> 827 Good morning #> 828 Good morning #> 829 Good Morning #> 830 Good morning! #> 831 mornin' #> 832 Hey, I had submitted a notebook entry to Vedant with my prototypes and why they should be used but he said it was incomplete. Was there something else that needed to be submitted? #> 833 May we begin the discussion? I assume we will be deciding which 5 prototypes to test? #> 834 @Nassim Tehrani: What do I need to do in order to catch up? I have not received an email since my last notebook and worklog. #> 835 How did everyone's designs turn out? #> 836 The five designs I created would allow us to test for ROM and Material as variables. #> 837 Similarly to Robert mine test best for seeing how ROM effects the skeleton's performance #> 838 Okay so I have a question about the design process. Was there any resource describing the 6 different ROM? #> 839 I think that it is definitely important to test ROM, but it seemed like aluminum was by far the best choice for materials considering its price and density. I think it is most important to test the different ROMs and the LiPO and NiCd Battery. #> 840 For example I used Pneumatics of course and then also used NiCd and Piezoelectric because those were what were best suited for my IC. That left Material and ROM. I did one Steel, one Composite, and one Aluminum all will ROM 1 which can compare the material only. Then I also did two more Steel prototypes but with ROM 3 and ROM 6 to compare the ROMs. #> 841 Looking at the variables we're allowed to test we should decide on just one or two to change and see how they effect performance, assuming we only get 5 skeletons we need to limit what we change as much as possible in order to get an understanding on how important they are to the skeleton #> 842 I think we should do ROM and Battery type #> 843 I agree with Carl #> 844 We already have data on the batteries though. I think it would be important to test Materials and ROM #> 845 With the Pneumatic Actuator the most effective ROMs to test would be 3, 4, and 5. Since battery life is unaffected until the 4th ROM #> 846 ROM for sure needs to be looked into as it will effect the overall functioning of the skeleton #> 847 So we agree on ROM #> 848 any suggestions on what else to check? #> 849 We have data on the materials too though. I think that Batteries have more possible flaws that need to be looked in to. #> 850 Yes I don't think any one opposes checking ROM. I think Material would be important to check because we don't have data on it like we do for the other variables(excluding ROM) #> 851 Didn't you check Materials Descriptions and Specifications #> 852 Okay never mind I figured it out. I would agree with the testing of ROM and Battery type. #> 853 But how much do we know the effect of material based on weight, price, and strength? #> 854 A fair amount, price for sure is a big factor, and the differences in strength weren't incredibly significant #> 855 @Carl: You think the data there is enough to go off of without testing it in the field? #> 856 The biggest variable in the materials was density, but the composite material although the least dense is just way too expensive #> 857 I agree with Peter, that was the point I was trying to make earlier #> 858 Well and if battery life becomes a big issue we can always revert to composite because of its ultra light weight #> 859 I dont know how valuable it would be to test materials since there just aren't as many variables within a material as there could be in a power source or ROM. #> 860 Alright so then Batteries and ROM? #> 861 Which would we assume to be our material then? Aluminum seems to be the most logical even though it has the lowest strength. #> 862 I agree with aluminum, the differences in strength aren't that significant compared to the differences in price and density. #> 863 Yes, despite Aluminum's low strength and bigger risk of corrosion I think it is the best choice #> 864 Is anyone opposed to Aluminum being a set control on all of our prototypes? #> 865 Yes, I don't like the idea of using the lowest strength but the steel is just way too heavy and the composite would compromise a reasonable market price. #> 866 Awesome, How about the control sensor? #> 867 No #> 868 Corrosion could be solved by coating it in something which wouldn't be too expensive. I agree to use Aluminum. #> 869 Piezoelectic, it's just the best all around Sensor #> 870 does Piezoelectric sound good to everyone? #> 871 Piezoelectric seemed to be a favorite from before. #> 872 I think the two batteries we should test are the LiPO and the NiCd, the fuel cell is just too expensive #> 873 Not necessarily, with 5 prototypes the most we could test is 3 with one battery and 2 with another #> 874 No argument there. So we still get to test 4 ROM's #> 875 Alright then my suggestion is to make the 5 prototypes all using aluminum, Pneumatic actuator and Piezoelectric ...I agree that ROM 3 to 5 should be tested, 3 will be our closest ROM to control but which battery should be used to test the ROMs? should we use PFC for one and then NiCd and LiPo for the other two? this should show us best how the ROMs directly effect performance and Batteries effect performance #> 876 You need the batteries tested to have the same ROM or else we won't know which variable is affecting our results. #> 877 The PFC is too expensive, we should stick to NiCd and LiPO, we only have 5 designs #> 878 So for the battery test it will be ROM 3 using a PFC battery in comparison to ROM 3 using NiCd and LiPo #> 879 Guys, we only have 5 designs! #> 880 Then for the ROMs we'll use PFC as a control battery so we can see how just the change in ROM effects the skeleton #> 881 does that make sense? #> 882 that is only 5 designs #> 883 Yes, I was just going to say that. #> 884 ROM 3 with PFC #> 885 ROM 4 with PFC #> 886 ROM 5 with PFC #> 887 ROM 3 with NiCd #> 888 Using a strong battery life PFC will allow us to better analyze the effects ROM has on performance. #> 889 I agree with Carl. I say two tests(one with each battery) and ROM 3, then we can do three more with one battery and test for ROM 4,5,6 or any other set of 3 ROMs #> 890 PFC is too expensive and doesn't meet performance standards, it would never make sense in a real life application #> 891 and ROM 3 with LiPo #> 892 5 #> 893 We stick to LiPO and NiCD #> 894 I am not suggesting we use the PFC in the final, just as a control so that we see how just the change in ROM will effect the skeleton performance #> 895 Is there a battery you would suggest in replacement? #> 896 Look as my set for a second. It compares our batteries and 4 different ROMs. Is there any problem? #> 897 LiPo-ROM 3, NiCd-ROM 3, NiCd-ROM 4, NiCd-ROM 5, NiCd-ROM 6 #> 898 The 6th ROM is too extreme, we would never meet battery specifications #> 899 I agree that we do not need to test ROM 6 #> 900 Ok how about we stick to NiCd then and we test the following: ROM 3 with NiCd, ROM 4 with NiCd, ROM 5 with NiCd, ROM 3 with LiPo and ROM 3 with NiCd and steel instead of aluminum, this could show us that maybe the heavier steel will not slow it down too much and greatly increase the payload #> 901 My session timed out and I lost my notebook entry I was working on, I will have it done soon. #> 902 @Joseph I think we should stick with aluminum, otherwise we won't get an accurate reading on the ROM #> 903 Ok how about we stick to NiCd then and we test the following: ROM 3 with NiCd, ROM 4 with NiCd, ROM 5 with NiCd, ROM 3 with LiPo and ROM 3 with NiCd and steel instead of aluminum, this could show us that maybe the heavier steel will not slow it down too much and greatly increase the payload #> 904 Which two ROMs should we test with the LiPO? #> 905 My suggestion allows for 3 prototypes specifically testing only the ROM completely isolated. #> 906 I like yours the best, but I think we should stick to aluminum for the 5th prototype and test one of the other ROMs instead #> 907 would you want to test ROM 6 or 2? are those really necessary to test when we have the opportunity to see if our assumtions about steel were correct? #> 908 We already decided on aluminum as the material, we're testing the effects of the batteries and ROMs I suggest that we test LiPO with ROM 3 like you proposed but also ROM 4 or 5 #> 909 alright I agree we, then I suggest LiPO with ROM 5 as the 5th one, the 3 to 5 will give us the best idea of how extreme the change in ROM can be with a LiPO battery #> 910 So final batch: #> 911 ROM 3 with NiCd #> 912 Correct #> 913 ROM 4 with NiCd, ROM 5 with NiCd, ROM 3 with LiPO and ROM 5 with LiPO? #> 914 any objections? #> 915 Ok, so we are moving ahead with the aforementioned batch. Good meeting, I've got to go to my next class. #> 916 Yes, I created the batch, results will be up later, don't forget to do your notebook eventually, good meeting, good luck #> 917 Also @Peter H: I would suggest deleting your first made batch in case we can only have one batch analyzed at a time #> 918 Hey Nassim, my group chat is blown up to half of my screen so my notebook, worklog and email are all inaccessible. Can you minimize this for me so I can continue my work? #> 919 Good Morning #> 920 Good Morning! #> 921 Good Morning #> 922 I can not submit my notebook entry, is there a reason for that? #> 923 Morning #> 924 @Nassim Tehrani: The last email I received was saying my worklog for the prototypes was complete and didn't get one after. I was trying to do the notebook entry about the Team Batch. #> 925 @Nassim Tehrani: Got the email and my notebook is now submitted. Thanks. #> 926 What is the subject of todays meeting? #> 927 Will we be starting soon? #> 928 Please allow them to take their time, a more in depth personal analysis of our results will make for a better, more efficient meeting...the more familiar we are with the results the better #> 929 I'm still working on my notebook #> 930 Is everyone ready? #> 931 alright, take your time Carl #> 932 I would agree. #> 933 As long as we all have our results, I think we should be able to start discussing. #> 934 I am almost done with the notebook. #> 935 What I noticed is that the increase in ROM produced better payload and agility but significantly set back the other performance features. The change in battery from NiCd to LiPo allowed for a much higher payload for about 60 dollars less and gave us maybe 24 minutes of extra use before needing a recharge. It also caused us to lose agility and safety but only so much that it was no longer ideal. It still met all minimum standards of the consultants. This leads me to think that our best route is to ideally forget about higher ROMs, even 4 was putting unnecessary constraints on our prototypes. At the same time we should not completely disregard the LiPO battery option as tweaking other features may prove that this is in fact a better battery choice. #> 936 I will elaborate on that at the meeting on tuesday. #> 937 @Nassim Tehrani: so may we log out and be done for today? #> 938 Thank you, see you all Tuesday. #> 939 @Nassim Tehrani: I have been having some difficulties with the workpro lagging on me or freezing up entirely from time to time. Nothing too extreme so I believe I've been able to keep up with all of our work but during our last meeting, I was cut out ent #> 940 @Nassim Tehrani: Ok thank you! #> 941 @Nassim Tehrani: My worklog has been submitted but not witnessed. Just want to make sure it got through. #> 942 Are we required to make a poster for the presentation or are we allowed to produce a different form of visual aid such as a powerpoint? #> 943 Morning #> 944 Good morning #> 945 Let's start! #> 946 yes #> 947 Yes #> 948 Have received any information about this poster yet because I cannot seem to find an email about a poster. #> 949 yes #> 950 We decided that during the last team meeting #> 951 The poster was just mentioned at the end of an email on here. Nothing described yet #> 952 we decided that the battery and ROM levels were the most pertinent variables and did our best to isolate them as to see how they would directly affect the skeleton's performance #> 953 That was the best way to use our tests since we could only test five designs. #> 954 We just decided which components of the exoskeleton were more or less the obvious choice for the final product and which ones needed more testing i.e. (the batteries and ROMs) #> 955 In reality, I don't know that they factored in much. A lot of them wanted a lot of different things and we were trying to keep as many variables constant as possible #> 956 Most wanted a high payload and safety standards so we factored what different elements would give us the best outcome to meet those standards. #> 957 The IC requests made us aware of what sort of attributes are important to the exoskeleton. Cost was one that got us deciding on using aluminum for our frame for example. #> 958 For the variables that we tried to control (the ones we kept the same from prototype to prototype) we did our best to choose the best features that would hopefully fit their standards #> 959 Yes, for example the choice of aluminum as Robert just mentioned #> 960 I would say that was our primary interest, as they are the ones who will use the exoskeletons #> 961 Yes, I think they just gave us certain areas to focus on that we may not have considered otherwise. #> 962 I agree, the consultants that specifically mentioned the buyers and users of the skeletons were most important such as the marketing or design consultants #> 963 Because of them our safety and agility are higher quality. #> 964 The only impact their interest had was minimizing the cost of the exoskeleton to accommodate their price restraints #> 965 I think the rescue workers' safety was important. We chose variables which allowed for the best agility or payload for example which did not compromise safety rating for it. #> 966 We used components like the Piezoelectric Sensor which had a high safety rating but also good all around attributes #> 967 Most wanted a cheaper, safer and faster equipment #> 968 I would say it was we got many different results and it gives us insight on which factors matter the most. #> 969 Yes, several of the exoskeletons fit within the specifications of all the consultants #> 970 yes, it seems that our first "control" skeleton would have been the best choice, excelling in almost all areas except payload #> 971 What I noticed is that the increase in ROM produced better payload and agility but significantly set back the other performance features. The change in battery from NiCd to LiPo allowed for a much higher payload for about 60 dollars less and gave us maybe 24 minutes of extra use before needing a recharge. It also caused us to lose agility and safety but only so much that it was no longer ideal. It still met all minimum standards of the consultants. This leads me to think that our best route is to ideally forget about higher ROMs, even 4 was putting unnecessary constraints on our prototypes. At the same time we should not completely disregard the LiPO battery option as tweaking other features may prove that this is in fact a better battery choice. #> 972 The trial was certainly successful for the variables we tested however I think that if we had been able to test our personal batches we could have likely created a more refined exoskeleton. #> 973 Naturally we wont find a perfect exoskeleton which will fill all our requirements and desires but the tests gave us back useful information which I would say were the results of a successful trial. #> 974 Yes, I agree that was the main one #> 975 The limitations in how many designs we could test. #> 976 Yes, realizing that it would be expensive or time consuming to the company to test a multitude of skeletons, it made sense that we had to limit our prototypes but it put serious constraints on what we could specifically look at #> 977 Knowledge on how certain variables effect the pneumatic actuator #> 978 We will be able to identify variables we want to test from earlier on. This will help us create tests that will maximize the variables we can analyze. #> 979 We will bring our data specifically with our Pneumatics and all the effects with it and other variables on our exoskeletons to compare with other actuators and their data. #> 980 The Pneumatic actuator works well with the NiCd battery and piezoelectric control system. It has approvable safety ratings and seems to lack only in payload and agility which is most likely caused by its inability to utilize higher ROM levels #> 981 I agree with Robert, but they also may be inferior to others in terms of payload and agility. #> 982 Our pneumatic actuators are very efficient and cost effective. #> 983 The use of Gas in the actuator as opposed to water makes for a more reliable and efficient use of energy and the Pneumatic design is safer than the artificial muscle outline which severely limits its payload abilities as the muscles are less supportive than the steel or aluminum piping used in our actuator #> 984 Yes, that pretty much sums it up #> 985 As for series elastic and electric it will be exciting to hear how those will compare to Pneumatic #> 986 good meeting team #> 987 In the time we are away from this class the next day or so should we begin work on the poster or should we wait for further instruction? #> 988 In which email was the presentation mentioned? #> 989 So I assume we are done for today? It seems that thursday we will be meeting with other teams #> 990 Thanks, have a good day #> 991 Hello Nassim, I am Peter. Nice to work with you #> 992 Hello everyone, I am Joe. Nice to meet all of you. #> 993 Hi everyone, I'm Cameron, nice to meet you #> 994 Hi everyone, I'm Cameron, nice to meet you #> 995 Hi Nassim, I can't seem to figure out what to do/how to complete the worklog portion of the process. Any feedback would be appreciated, thanks. #> 996 Hi Nassim, I can't seem to figure out what to do/how to complete the worklog portion of the process. Any feedback would be appreciated, thanks. #> 997 Sorry everyone i forgot to introduce myself on Tuesday, I'm Fletcher. Nice to meet you all. #> 998 I also am having a difficult time figuring out how to complete my worklog entry. Could somebody help me out, thanks. #> 999 Hi, I'm Amirah. sorry for not introducing myself last tuesday. had diffulties with my work spcae. #> 1000 *space #> 1001 Are we still missing Kevin? #> 1002 I'm here, I wasn't able to log in during the Tuesday session but now it's all figured out. #> 1003 That's good, I was just wondering if there was a mistake or something. How far is everyone? #> 1004 Yes, I am working on the research on exoskeletons #> 1005 Yes, that works. #> 1006 Yes, that works. #> 1007 I don't think ill be able to finish my research by then. I cannot access the movement of a body in 3-dimensional space document #> 1008 Okay I will #> 1009 The graphs will indicate which power source and control sensor to use. I am actually working on the graph right now so I dont know which is best yet #> 1010 I haven't made it to the graphing portion yet, I just received that email now #> 1011 I haven't made it to the graphing portion yet, I just received that email now #> 1012 I've only finished the power source graph but my graph shows that NiCd batteries have a good balance of all five qualities. #> 1013 I have not completed it yet #> 1014 I agree the NiCd battery has the best average of the five qualities #> 1015 For power sources the NiCd was obviously the best but the control sensors all even out in the end and just depend on what is the goal of the exoskeleton they are used for #> 1016 I am still constructing the graph. Will give opinion when I am done with it. #> 1017 I am done with the graph, summary, and recommendation. Can we please adjust a time to later hold this meeting? #> 1018 So what time and day will this new team meeting be? #> 1019 So what do we do now? #> 1020 We have not gotten what we are supposed to do after the graphs and all the worklogs and notebooks are done for that right? Or am I missing something? #> 1021 Can we immediately do the meeting now since everyone is logged in? I think thats supposedly the next step.. #> 1022 yea I've completed everything too, so whenever everyone is ready #> 1023 yea I've completed everything too, so whenever everyone is ready #> 1024 We dont have everyone yet #> 1025 who is missing? #> 1026 Kevin #> 1027 I'm here #> 1028 Now we have everyone #> 1029 Which one should be the ideal choice #> 1030 They showed us which sensors/batteries excel in specific areas of interest #> 1031 They showed us which sensors/batteries excel in specific areas of interest #> 1032 I found that the combined qualities of the NiCd battery and the piezoelectric sensors seemed best #> 1033 Also the graphs and experiments done compared how the batteries/sensors were able to preform under different conditions #> 1034 I think combined the NiCd and Optic Binary might be the best #> 1035 There was no obvious choice for the sensor #> 1036 I agree with Joseph. Though I would say almost everyone agrees using NiCd is best but its hard to say for the sensors #> 1037 They all seemed to have at least one area of weakness #> 1038 They all seemed to have at least one area of weakness #> 1039 I agree but the best choice for battery was the NiCd #> 1040 So it depends on what the overall goal of the individual exoskeleton is #> 1041 The only reason I do not think that the optic binary sensor is ideal is because of its low safety rating #> 1042 The only reason I do not think that the optic binary sensor is ideal is because of its low safety rating #> 1043 Yeah the optic binary sensor provided ideal cost and recharge interval values but its performance was not the best #> 1044 I also agree with Joseph that the choice for the sensors depends on what the overall goal of the exoskeleton is #> 1045 The performance of the NiCd would outweigh the weakness of the optic binary #> 1046 My choices are based on which one is more well rounded, though may not excel in every element but it could at least perform the basic elements #> 1047 The more area inside the graph the better the battry/sensor is #> 1048 I thought that at times the graph could be a little misleading because if you look at the size alone, you're assuming that each quality is valued equally. #> 1049 I would prioritize safety because this aspect is more important for the user #> 1050 I think safety should definitely be deemed an important attribute since we are dealing with lives of people #> 1051 I think safety should definitely be deemed an important attribute since we are dealing with lives of people #> 1052 I tried to pick a battery that was able to preform well and also had a good safety ranking #> 1053 I agree safety should always be important in our choice #> 1054 Safety should be important but one aspect of these exoskeletons is to used in life threatening conditions like fires or earthquakes and other such types of scenarios. At that point the safety of the exoskeleton wont actually be the most important contribution to the safety of the user. The user is going to need speed and agility or strength #> 1055 I think we should decide which battery and control sensor works best for the exoskeleton #> 1056 I think we can all agree on the NiCd #> 1057 I think we can all agree on the NiCd #> 1058 Well the NiCd seems to be the best battery #> 1059 Which means we need a prompt for the selection of the sensor #> 1060 I think the strain gauge works best because it is fairly good on all aspect except the recharge interval #> 1061 Yea I agree with the strain gauge #> 1062 Yea I agree with the strain gauge #> 1063 The piezoelectric sensor was an all around good choice from my data #> 1064 If we choose the NiCd with the strain gauge look at the overall recharge interval #> 1065 Yes the strain-gauge did preform well but the piezoelectric sensor had a better recharge interval and safety ranking #> 1066 Very bad #> 1067 To get the best overall product we would need to choose a combination of the two that results in the best #> 1068 NiCd only real weakness is recharge interval so I think that piezoelectric is the way to go #> 1069 Maybe to start considering other variables then just the ones presented in our data #> 1070 According to the design gantt chart we are going to be deciding which material to use next #> 1071 So finding more variables like Fletcher said #> 1072 Yes #> 1073 so our next task is conducting more research? #> 1074 so our next task is conducting more research? #> 1075 Yes #> 1076 Wait I agree with Camerons question #> 1077 Yes #> 1078 We forgot about Peter #> 1079 Working on it, almost done. #> 1080 Did you get receive it? #> 1081 Ok #> 1082 Thanks #> 1083 Sorry team. Again I was experiencing many technical difficulties this class period. However, I found that the NiCd battery was the best overall, and the strain-gauge is the best control sensor #> 1084 I completed my internal consultants worklog yesterday but I have not received an email yet #> 1085 I have not received anything in regards to our next task #> 1086 I have not received anything in regards to our next task #> 1087 I have not gotten an email either #> 1088 So what do we do now? #> 1089 same #> 1090 Just got it #> 1091 I got it too #> 1092 So we each need to pick one consultant #> 1093 Anybody have any preferences? #> 1094 Not really #> 1095 Not really #> 1096 One of the consultants is going to have two of us #> 1097 I am online #> 1098 I am online #> 1099 I can do DaShawn Edwards the biomedical engineer #> 1100 I will take meredith yamasaki-nolan in marketing and sales #> 1101 So who does everybody else want? #> 1102 I can take meredith yamasaki-nolan #> 1103 Im doing meredith yamaski-nolan #> 1104 Ill do Paulo Henriquez, the qulity engineer #> 1105 Ill do Paulo Henriquez, the qulity engineer #> 1106 I can do laura rivers #> 1107 Okay so we still have benjamin and laura open #> 1108 I will do laura #> 1109 I will do laura #> 1110 I'll do Benjamin #> 1111 What sources is everyone reading? #> 1112 Im reading "Actuator Descriptions and Technical Specifications" #> 1113 Im reading "Actuator Descriptions and Technical Specifications" #> 1114 Are you reading any of the pneumatic or electric level performance metrics? #> 1115 Also "The Effect of Exoskeleton Range of Motion on Series Elastic Actuated System Level Performance Metrics" #> 1116 I'm sorry for signing in late. I had problems with my internet connection. #> 1117 Is there any part left for me to read? #> 1118 I think we only have to evaluate the series elastic and then compare different combinations of other parts and materials with it #> 1119 Are you sure Kevin? in the email Vedant says record the affects of each actuator? #> 1120 And Amirah read the email and then look up the info for Laura #> 1121 Okay, will do #> 1122 With each actuator or just the series elastic? #> 1123 Hello #> 1124 @Nassim Tehrani: I was just about to write to you. I have completed all the tasks up to this point, yet I have not received an email for the next task. Any ideas on what may be causing this? #> 1125 Yea ive done everything as well and have not received an email #> 1126 Yea ive done everything as well and have not received an email #> 1127 Okay sounds good. I never received the email about creating the REDD design either. I'm not sure if this is the next task but I know I have to do this based of the flow sheet. #> 1128 I am also waiting for the next task. #> 1129 okay #> 1130 okay #> 1131 So how do we start? #> 1132 All of the prototypes can be seen on the REDD tool I meant how do we start on deciding which to chooce? #> 1133 I am looking at the balanced design we each made and it looks as though the general consensus is ROM 4 and Piezoelectric #> 1134 yea we all chose composite material for a good portion too #> 1135 yea we all chose composite material for a good portion too #> 1136 How many designs are we allowed to test? #> 1137 yea I know for the prototype that I tried to balance, the NiCd worked pretty well #> 1138 yea I know for the prototype that I tried to balance, the NiCd worked pretty well #> 1139 I agree but it seems we different opinions on the battery we all chose #> 1140 Yeah it looks the same to mean and most of the balanced ones seem to have NiCd #> 1141 three out of four have the NiCd #> 1142 It looks like the series elastic actuator was unanomously used as well #> 1143 we are choosing 5 #> 1144 we are choosing 5 #> 1145 So what material should we agree on #> 1146 Se had to use the series elastic haha #> 1147 We* #> 1148 oh well i didnt know that. kinda behind #> 1149 So Composite, NiCd, SE, Piezo., ROM 4 should be one #> 1150 yea kevin I agree #> 1151 yea kevin I agree #> 1152 sounds good to me #> 1153 I thought the composite material was the best choice #> 1154 I think we are going with Composite for the balanced one. #> 1155 So do we have one of those or are we making a new one? #> 1156 One of my prototypes was exactly that combo so we dont need to make another I dont think #> 1157 One of my prototypes was exactly that combo so we dont need to make another I dont think #> 1158 Kevins balanced design works for that #> 1159 Yep your two are the same. So next prototype #> 1160 since there are 5 internal consultant preferences should we have a prototype of best fit for each #> 1161 since there are 5 internal consultant preferences should we have a prototype of best fit for each #> 1162 I think we should make a design that focuses a minimum of two categories not just one #> 1163 Should it focus on one category? #> 1164 It also has to meet the other requirements so it cant focus too much on one thing #> 1165 no #> 1166 did we all make a balanced prototype for our internal consultant? #> 1167 did we all make a balanced prototype for our internal consultant? #> 1168 oh because I was going to say, our 5 prototypes can be a balanced prototype for each consultant #> 1169 oh because I was going to say, our 5 prototypes can be a balanced prototype for each consultant #> 1170 from* #> 1171 from* #> 1172 We didnt get all the prototypes made so that approach wont work. The best we can do I think is just decide right now for four focus protypes and design them #> 1173 We would also have six final prototypes then and some of the might end up being identical #> 1174 I thought there is only 5 internal consultants #> 1175 I thought there is only 5 internal consultants #> 1176 we already have one design #> 1177 We already decided on an overall prototype above. So four left #> 1178 @Nassim Tehrani: im working on it at the moment #> 1179 I think the best thing we could do was have one main focus category we want, like safety, and then have one protoype also focus on the other four categories, each with safety or whatever top category we picked #> 1180 sounds good #> 1181 sounds good #> 1182 I think we shouldn't just focus on one category but maybe two #> 1183 Then we would have to have prototypes with three categories, Im saying always worry abou one category and tha\\enadd one of the other four categories to the main one. So each design has two main categories #> 1184 yea what happened #> 1185 yea what happened #> 1186 sorry my computer just stopped working #> 1187 That happened to everyone #> 1188 @Joseph H: what you said before was quite confusing, can you give an example? #> 1189 Oh #> 1190 About the four remaining examples? #> 1191 @Amirah: About the four remaining examples? #> 1192 @Joseph H: Yes #> 1193 Oh I see. Understood #> 1194 i think hes saying we have an emphasis on safety throughout all of the prototypes, and then on each one emphasize one of the other attributes as well #> 1195 i think hes saying we have an emphasis on safety throughout all of the prototypes, and then on each one emphasize one of the other attributes as well #> 1196 So if were to pick a main category would it be #> 1197 Yeah Cameron has it. And I think safety would be the best choice to do this four #> 1198 I am guessing we wont all really be able to meet again today so should we just split up the prototypes and have each person make a different one? #> 1199 For example I could do safety and cost and then put that prototypes up there, and then after we have all five we make a batch out of the final designs #> 1200 put that prototype* not plural #> 1201 ok I will do safety and recharge interval #> 1202 I've got safety/payload #> 1203 ill do that #> 1204 ill do that #> 1205 So we still need a safety and agility #> 1206 Okay we will all do those. Put them up in REDD and I will make the batch that we can all attach to our notebooks later, or whoever makes the last one can do that. Doesnt really matter who makes it, but call it Team Final Solutions #> 1207 So there are 4 final prototypes right? #> 1208 ok #> 1209 sounds good #> 1210 does anyone else not have a workspace? #> 1211 does anyone else not have a workspace? #> 1212 Okay so we have the safety and cost and payload and cost prototypes done #> 1213 my workspace still isnt up... #> 1214 my workspace still isnt up... #> 1215 its working now, I messed up my title for the design it should read "Agility and safety final prototype" #> 1216 its working now, I messed up my title for the design it should read "Agility and safety final prototype" #> 1217 whoever is making the 5th prototype can create the batch #> 1218 whoever is making the 5th prototype can create the batch #> 1219 my workspace is still not working so someone else is going to have to do the last one #> 1220 I could get in earlier but now I cant get in again #> 1221 I haven't been able to get in at all #> 1222 I dont know how we can get it done by 9 tomorrow morning #> 1223 Okay I made last one but named it wrong, it is safety and recharge not cost and recharge. I also made the batch and called it final designs #> 1224 I still can't get in so I don't really know what to do...if you have any suggestions that would be great #> 1225 I can easily get in now. I think it was just a timing thing #> 1226 good morning #> 1227 good morning #> 1228 good morning #> 1229 good morning #> 1230 Good morning #> 1231 Good morning. #> 1232 Sorry the recharge and cost is actually recharge and safety. I misnamed it. #> 1233 Yes, I believe a #> 1234 i am almost caught up #> 1235 The REDD designs and notebook entry #> 1236 @Nassim Tehrani: I have not yet received the REDD results yet and in the email Vedant sent he said to ask you if I did not receive them. #> 1237 Yes #> 1238 I just got them, thanks #> 1239 Is anybody else done? #> 1240 I am readuy #> 1241 ready #> 1242 for today, the meeting is about choosing 5 designs right? or are we going to just choose based on last Tuesday's discussion? #> 1243 I just finished #> 1244 If you have time before or during the meeting you should look at the results of the other batch, I dont know why mine was tested but anyways if you look at the device three cost effective I think it actually meets all the requirements #> 1245 ok #> 1246 ok #> 1247 Sounds good #> 1248 We wanted to include one balanced design because we all created one in our individual design processes and the other four we decided should focus on one attribute, in this case safety and one other category. #> 1249 We chose one attribute to be focused on in each of them, and then paired it with each other attribute to get four of the designs. The fifth was just an overall best combination #> 1250 It provided us with insight as to what attributes the company values #> 1251 It provided us with insight as to what attributes the company values #> 1252 We tried to met the requirements of each consultant but we focused more on meeting the requirement of the consultants that we were focusing the attributes on #> 1253 We wanted to at least try to create 5 designs that all touched on one of the categories that the consultants wanted #> 1254 That was the main reason we focused on safety for all of the prototypes #> 1255 Safety in general was our number one priority #> 1256 We figured a higher safety along with a better agility would be the best for the workers #> 1257 the worker's safety is actually the primary concern when we design the exoskeleton. #> 1258 We also thought that a higher payload would also contribute to a greater safety #> 1259 Thats why most of the prototypes ended up using the ROM 4 #> 1260 Some of them were, some werent #> 1261 I think the balanced combination and final recharge interval and cost were the best devices #> 1262 most of the prototypes lack in one attribute #> 1263 most of the prototypes lack in one attribute #> 1264 The recharge interval quota was hard to meet #> 1265 That might just be the case with all Series Elastic actuators though so it might be out of our control #> 1266
