A Prototype for Smart Prosthetic Legs-Analysis and Mechanical Design
In this paper, we designed a prototype of powered above-knee prosthesis. Compared with other prototypes available in the literature, our designed prosthetic leg employs a redundant actuator concept to overcome the challenge faced by the single-motor transmission systems. The redundant actuator also enables the prosthesis to be partially functional when the prosthesis loses power. Finally, in order to provide optimal control parameters for designed above-knee prosthesis to perform a smooth level-ground walking task, an inverse dynamic model based on Kane’s method is constructed.
