Research on motion capture technologies to develop a bionic leg

Abstract

This paper explains how motion capture technology can effectively be used to detect, analyze and quantify human activities such as walking, standing, sitting and climbing stairs. This technology is expected to be used for active (eg: motor driven) knee replacements used by above knee amputees. A motion capture system is implemented using inertial sensors and force sensors which quantify gait parameters. The results are used to design a finite state control system for an active above knee prosthetic.
