Abstract We developed a novel control architecture for robotic leg prostheses that adapts online at each step to provide biological accurate function based on the user gait pattern. The user-adaptive control can restore physiological joint energetics and does not require any tuning–the user can don the robotic leg and go. The movement of the prosthesis during […]

Abstract We designed a robotic system that can transform a conventional passive prosthesis into a powered robotic leg, thus allowing transfemoral amputees to perform activities that would not have been possible with their prescribed passive prostheses, such as climbing stairs. The Robotic Retrofit Prosthesis comprises two main functional elements: (1) a powertrain, which includes the motor […]

Abstract We developed a novel hybrid actuation system for robotic knee prosthesis that combines a conventional passive spring/damper system with an innovative variable transmission based on slider-crank design. The Hybrid Knee is as lightweight as a passive device, and as strong as a heavy fully-powered prosthesis, helping subjects to stand up from a sited position and to […]
