DARPA Creates “A New Hope” for Amputees

US military veterans Fred Downs and Nardi McCauley lost their arms during service to their country. As participants of a Department of Veterans Affairs (VA) research study, they have become the first individuals to receive the Defense Advanced Research Projects Agency’s (DARPA) LUKE arm system. The LUKE (Life Under Kinetic Evolution) arm is a novel robotic prosthesis that attaches to the amputee’s limb and replicates many functions of a human arm with the help of sensors and an easy-to-use controller.

This device allows users to control multiple joints simultaneously and performs a variety of grips with adjustable grip forces. This technology was made possible by the Army Research Office and funding assistance from the US Army Medical Research and Materiel Command (USAMRMC). The working prototypes were designed by the DEKA Research and Development Corporation and built by Mobius Bionics, a commercial-scale manufacturer borne out out of the VA’s development efforts after years of research and testing.
