A measure of capability in a prosthetic arm is "degrees of freedom," an engineering term that defines the ways a body or system can move, such as rolling, pitching, or swaying. With 10 powered degrees of freedom, this arm—created by Deka and funded by the Defense Advanced Research Projects Agency and the U.S. Army Research Office—has far more available capability than anything on the market. Moreover, the light-weight arm hits the scale at the same level as the average female arm—roughly eight pounds. Still undergoing development, the prosthetic does not yet have a release date or price. The arm is the brainchild of inventor Dean Kamen, creator of the Segway and founder of Deka.
