Abstract
A prosthetic arm apparatus comprising a plurality of interconnected segments that provide the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connected to one another and connectable to a harness mount that may be adorned by the user. Each segment of the plurality of segments includes an actuator providing a portion of the movement capability, and each segment may operate independently of each of the other segments of the plurality of segments. One segment of the plurality of segments includes a non-backdriving clutch that transfers power from the actuator to an output interface of the segment when the actuator is actuated to generate movement of the output interface in either of two opposing directions and prevents backward transfer of power from the output interface to the actuator of the segment in both of the two opposing directions.
