The Luke Arm, created by Dean Kamen's DEKA R&D Corp., was a project initiated by DARPA to develop a prosthetic arm for wounded warriors more advanced than those previously available. The Arm can be configured for below-the-elbow, above-the-elbow, and shoulder-level amputees. The full arm has 10 powered degrees of freedom and has the look and weight of the arm it replaces. (more info here) Through trials by DEKA and the Dept. of Veterans Affairs, the Arm has been used by dozens of amputees for a total of many thousands of hours. Commercialization is still pending.
