Walking cycle control for an active ankle prosthesis with one degree of freedom monitored from a personal computer.

This paper proposes a fuzzy control algorithm for human walking cycle of an active ankle prosthesis for people who have suffered amputation of the lower limb, the system has one degree of freedom in the sagittal plane. Also, a biomechanical analysis of foot and ankle is shown to define the phases of plantar support and swinging. The used actuator is an intelligent servomotor, Dynamixel MX-106T which has torque, current and position feedback, among others, allowing real-time telemetry of the prototype implemented in a microcontroller system.
