VA Innovation Creation Series Free 3D model

Prosthesic Arm, made for the veterans.

The arm is designed simply, and is based in the lever principle. The finger rotates on the screw axis making the hand able to grip things. The lever is activated with a rubber material that being elastic pushes the finger to grip things(black rubber material ilustrated in two pictures). Based on the 'Keep it simple' filosophy.

When the prothesic arm will be 3D-printed, the fingers can also be covered of rubber in order to improve the grip of the hand.
