DARPA team offers first direct neural prosthetic arm prototype

An international team led by the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., has developed a prototype of the first fully integrated prosthetic arm that can be controlled naturally, provide sensory feedback and allows for eight degrees of freedom—a level of control far beyond the current state of the art for prosthetic limbs. Proto 1, developed for the Defense Advanced Research Projects Agency (DARPA) Revolutionizing Prosthetics Program, is a complete limb system that also includes a virtual environment used for patient training, clinical configuration, and to record limb movements and control signals during clinical investigations.
