This bionic hand uses an arduino nano V3 to controll 7 servo's. The hand is modelled after my hand so I could make a mold that fits over it.
All stl-files are free to download and can be found on thingiverse. The link to thingiverse is on this page somwhere left down.
I made the mold using plastigel10.

I like this project very much! I'm a left hand amputee myself, and I'd like to build this and try it out. Are there assembly instructions? The video moves much too fast to follow.
Hi, My son and I built a very similar project for a prosthetic hand competition. We found several advantages to using gear motors (strength, torque, size ..) similar to this: https://www.ebay.com/i/311900465658?chn=ps
And we were able to use back EMF to measure force / speed using the method outlined here: https://robidouille.wordpress.com/2009/09/20/back-emf/
I'm not and EE but it was very effective and worked well for us.
Very nice and thank you very much for the links. They are quite usefull.
