As my blog posts near their end, I thought that it might be nice to take some time to explain a bit about how the hand electronics and code work. This post should give the reader a fair bit of information about what the code actually does, and may briefly touch on how the electronics work with the code. I want this post to be pretty thorough, so if you have any questions or want anything clarified by the end, feel free to ask in the comments!
It’s been two weeks since my last post, and a great deal has happened since then. Most notably, the second version of the handstand has been constructed and set up. Take a look at the video below for a quick demonstration of that and the new and improved debug program (The thing graphing data on my laptop). In the video I demonstrate the new debug program screen, the hand opening and closing with the EMG system, and all of the hand functions that are currently loaded: pinch, peace sign, rock sign, and two types of finger wave. Most of the functions are placeholders, but they’re still fun to see.
There are four things that I have to do in the next few months:
1. Order motors and potentiometers and modify (“hack”) the hand to use them.
2. Set up a meeting with the recipient of the hand (to test EMGs).
3. Begin printing a new hand on the FormLabs printer.
4. Commit the code to GitHub
Oh, hey, that last one’s done! Continue reading
