This is my Grade 10 Passion Project. This year, I decided I’m not going to make the same mistakes as last year: namely, working on two projects due at the same time at once. Thus, I’ve finished my nestbox and am now focusing exclusively on this (Well, almost. I am still working on my other classes, any side projects that might be fun, Solar Max, STEAM Ambassador stuff, and all that other stuff. I want to focus, not completely burn out my interest in this project like I did last year.)

Handsy is a working prosthetic hand. It has a force sensor in the armpiece, and those sense muscles in the forearm contracting and relaxing and send what they sense to an arduino board. This board decodes these signals and sends commands accordingly to two servo motors that open and close the finger by tensing and relaxing strings.

There are still some problems:

1. The thumb doesn’t work
2. the armpiece doesn’t hold very well unless there’s a lot of tape, which leads to:
3. The arm piece is not very smooth, as I didn’t have time to sand it. That means it scratches up the forearm pretty badly, and
4. the fingers are not very strong, because the servos are not very strong

I am still deciding whether I want to continue this project next year, but if I do, I already have some ideas about how to fix these. For now, though, this is Handy.
