Abstract

In this paper we described a new kind of a powered knee and powered ankle prosthesis for individuals who have suffered a complete or partial lower limb amputation. Our prototype prosthesis consist of two modules, the ankle module and the knee module. The first contains a unidirectional spring configured in parallel with a force-controlled actuator. This spring is intended to store energy in dorsiflexion, and then released it to assist power plantar flexion. The knee modules consist of a series of elastic clutch actuators and a unidirectional spring positioned in parallel to the motor. Preliminary results show two modules designs and ankle module prosthesis prototype almost complete. Two modules working together will enhance the performance of amputee individual, producing more natural gait and reducing the metabolic cost at walking in level-ground.
