20. Final Project

Summary

An open source, robotic hand that plays Jokenpo using buttons and a PC interface. Made completey with Fab Lav components

The idea was born because of several reasons.

FIRST- I get a very nice feedback of my tutors and weekly global evaluation about the machine week assignment. They love it.

SECOND- I have all the components that I need to improve and make this project better.

THIRD- Everybody love a robot hand.
