Ben - Prosthetic Hand

> This prosthetic hand still in development

### History

I've been desiging this hand for a local child that was born without one of his hands. Today he is only 5 years old and uses a cosmetic hand, because any other functional hand is almost U$ 3.000.

This hand will fit into his "arm glove" (that is a kind of adapter he uses on the arm the put the hand).

### Description

Currently the hand has only one degree of freedom, where only the thumb moves using a servo motor. This way he can at least grab things. I'm working on use the same servo motor to move the 2 upper fingers, in order to get a better grip.
