I am back this week with some ground breaking news! So my project has culminated itself in a very different way now. What I was going to do was get EMG Data from my hand, and analyze the forces in play with simulations. Well there is good news and bad news...
So for my project, I was planing on using EMG's and getting Force data from the simulations, but the social aspect and the analysis of social attitudes seen in various papers are interesting me. With the simulations, it would have taken far too much time, and that would mean I could not get enought data. So that is not going to work out. That was the bad news.
Now for the good news! So my new methodology is more straight forward than what I was planning to do. For the new experiment, I will be analyzing the same motor function of grasping, but the slight difference comes in the way it will be observed. I will be using the prosthetic and controlling it with my EMG's. The same EMG's I would put into moving my hand, I would use to move the prosthetic, and that would be done using an EMG sensor and a separate program to translate the EMG's to the prosthetic. I hope that makes sense so far.
Now with three different objects, I would use my EMG's to run the prosthetic and my hand, and grasp the object. With a primary recording of my muscle movement, with a myograph of when I clench my fist, and grasp the objects, I would see if the hand can replicate the movement using the same EMG's.
So this week was essentially my first main trial and error, and it showed me that what I was doing was on a scale unlike the nature of this project. I wanted to do a lot in an amount of time, that I cannot really do. Other than those important developments, I will continue to look through papers, and I will be doing a mid-week update for week 7 about the paper I am currently reading through.
I hope all of that makes sense. I will answer any questions in detail in the comments below and in my mid-week update. Thank you!
Hey Sri! I am so happy that you have found a new facet in prosthetics that really intrigues you. My question is, just to make sure I understand what your new path is, are you basically looking at how similarly the prosthetic works compared to the regular arm using the EMG's? Will you also be looking into how it could affect a prosthetic user? Thank you, and I can't wait to see what you learn next week!
ReplyDeleteHi Saleena! Thank you! So with the new project, I will be using my EMG's to control the arm and pick up objects. And with attached sensors to the prosthetic and my hand, I would get the motion data and then analyze that to see how the prosthetic approaches the different objects. I personally experienced using a prosthetic this week, and it was one of the hardest things, so I am going to also talk about what I felt when doing that. Thank you!
DeleteSri,
ReplyDeleteI an glad that your project is moving along well and that you are able to adapt your project in order to continue. Good luck and I cant wait to read more.
Hi Bianca! Thank you!
DeleteSri, your discoveries are quite fascinating and I'm content with the progress you have made. Good luck and keep up the good work.
ReplyDeleteHi Kayan! Thank you!
DeleteHi Sri! It's great that you recognized some of the necessary adaptations to be made in your own work. I'm glad you could come up with a new way to do this project without losing time or knowledge. How did you propose said shift to your mentors? Can't wait to see how more trials go!
ReplyDeleteHi Julia! Thank you! Yeah, I worked through and realized that with my old methodology I couldn't really get anywhere, so then we talked it over and realized that in the time left, this was the best direction to take the project. Thank you!
DeleteHi Sri! I think it's so great that your project is moving along smoothly. What errors did you encounter during your first trial? How are you going to include the social aspect of prosthetics into your project? I'm looking forward to next week's post!
ReplyDeleteHi Michelle! It wasn't so much that there were many problems with my first trial, it was just that that method was too time consuming and harder to do. So we formulated a new way of obtaining and analyzing the data. My project is an overall analysis of prosthetic design, so for part of it, the social circumstances and situations influenced the design and development, so I want to focus on that too. Thank you!
DeleteIt's amazing that you found a new approach to observing prosthetics and a new, more efficient methodology! How will you change your next "trial" to account for this one's errors?
ReplyDeleteHi Fajr! Yeah, so for the first part of my project, I wanted to analyze the EMG data, but that aspect would take way too long. So now, I am focusing on the motion data that I obtain from my trials with the prosthetic and my arm, both picking stuff up. Thank you!
DeleteHi Sri! I'm glad you didn't lose any time to reroute your project. Will your overall project have any shortcomings that you didn't expect at first? Has your end goal changed? Can't to see what else you do!
ReplyDeleteHi Sydney! Yeah, unfortunately, I won't be able to analyze how the prosthetic does with my EMG data, because that is the aspect that would take too long, but with the new data, I can see how the prosthetic approaches an object and how my hand approaches an object, both using the motion tracking data that I obtained. The end goal is still the same, but I have shifted focus towards looking at more papers, and looking at less data. Thank you!
DeleteHey Sri, I'm glad you're back! How will the EMG data relate back to improving the design of the prosthetic? I'm excited to hear more.
ReplyDeleteHi Anthony! So earlier, I wanted to analyze the EMG data but that would have taken way too much time. Now, I will be using my emg's to control the prosthetic and my hand, and then attach motion sensors to my hand and the prosthetic to obtain the motion data, to see how the prosthetic and my hand respond and move with the different shapes. Thank you!
DeleteSri,
ReplyDeleteThis sounds like a lot of work. It was a little confusing but after reading through the description a few times I think I got it! I hope that although there is a lot more work and studies to be done that you can continue your research outside of this SRP. See you next week!
Audrey
Hi Audrey! Sorry about that, I will explain it in a bit more detail in my next week post, Thank you!
DeleteHi Sri. Sorry to hear that you things didn't go as originally planned, but at least you found a solution. But, I was wondering if your new method of using the EMGs from you hand to transfer to the prosthetic was more efficient for data collecting, then why did you originally plan to go with simulations before? I'm curious as to why it wasn't your first choice to begin with, because this new way sounds like it would be more accurate than a simulation which is just probability rather than concrete data. Anyway, can't wait to hear from what you find in the data collected.
ReplyDeleteHi Jason! So the simulation and real life stuff, would both be used to collect motion data, the x,y, and z movements of my hand and the prosthetic, I just ended up doing it in reality because it was simpler and gave me data quicker. I should have probably put more thought into it, but in the end, it turned out well. Now, rather than analyzing the emg's, which would have taken a lot of time, I am using just the coordinate data to observe the motion of the prosthetic and my hand when I lift the objects. I hope that helps! Thank you!
DeleteHi, Sri! It's great that you were able to find a new way to do your research! Just a quick question: what types of objects did you want to use to study, or in other words, what qualities do you want these three objects to have? Sorry if you didn't think that far ahead yet. Can't wait to see your next post!
ReplyDeleteHi Korina! I ended up using a cylinder, a box, a baseball, and a roll of tape. I wanted the objects to be different shapes and I wanted to see how the prosthetic approached the different shapes. So I ended up using the prosthetic and my hand, both with motion tracking to pick up these objects, and I obtained x,y, and z movement data. Thank you!
