ABSTRACT
The purpose of this paper is to describe and evaluate the design and testing of a control system and test platform for an Active Prosthetic Knee (APK). The research scope includes mechanical design, sensing system, and motor (motion) controller of the Active Prosthetic Knee. The main objective is to produce an affordable yet rugged active prosthetic for above-the-knee amputees in developing countries. The main advantage of an active prosthetic is its ability to more accurately mimic the motion of a healthy limb without producing strain on the patient's muscles. The APK needs to be able to decide when to move by analysing the motion of the healthy leg without the use of expensive sensory system.
