Hugh Herr and his Biomechatronics research group at the MIT Media Lab have developed the first powered ankle-foot prosthesis. The novel prosthesis is capable of propelling the wearer forward and varying its stiffness over irregular terrain, successfully mimicking the action of a biological ankle, and, for the first time, providing amputees with a truly humanlike gait. Herr created the device through the Center for Restorative and Regenerative Medicine, a collaborative research initiative that includes the Providence VA Medical Center, Brown University, and MIT.
