After working as a professional design engineer for several years I wanted to try designing a new 3D printed prosthetic arm/hand.

This project aimed to incorporate a relatively high number of motors/degrees of freedom into a the palm and wrist of a bionic hand. Essentially I wanted to create a design that had high dexterity in terms of finger, thumb and wrist movement, yet was still compact enough that it didn’t require a forearm section to house motors and electronics.

The benefit of such a design in my mind was that it would offer a person who has lost their hand and wrist a prosthetic device which still has advanced movements capabilities.

I have written about the current state of this project and my design approach extensively in my blog posts, if interested I highly encourage you to have a look at them.
