Successful walking with a biologically-inspired below-knee prosthesis

In this paper, we present the results of walking experiments with a below-knee amputee fitted with a biologically-inspired prosthesis. The design of the prosthesis is described together with the characteristics and working principle of its actuators. First experimental results with an amputee are presented that demonstrate the encouraging performance of the prosthesis in restoring ankle torque to the user during level walking.
