3D printable Exoskeleton arm design

Exoskeleton arm design

This is a preliminary work in progress design for an open source 3D printable exoskeleton arm brace to assist the disabled to raise their arm.  As someone with a form of muscular dystrophy called SMA, I have significant difficulty lifting my arms.  Similar devices exist, but they are cost prohibitive for most people and not covered by insurance.  I wanted to create an open source, inexpensive exoskeleton arm brace that utilizes both springs to offset arm weight and a motor to raise the individual’s arm that would be free to download and modify.  Please note that for legal reasons, this is not intended as a medical devise and I make no warren tees nor can I vouch for the safety of this device as it is purely for experimentation.  Part of the concept is that this arm brace will allow additional snap on attachments or modifications.
