Actuated leg prosthesis for above-knee amputees

摘要

An actuated leg prosthesis for above-knee amputees comprises a knee member (12), an elongated trans-tibial member (14) operatively connected to the knee member to allow relative rotation, and a serial elastic actuator (16) set between the knee member and the trans-tibial member to cause a relative rotation between the knee member and the trans-tibial member. The serial elastic actuator comprises a motor coupled with an elastic device
