Design, development and realisation of an active driven knee-prosthesis with bevel helical gearbox

This paper presents the development of an active driven prosthesis for transfemoral amputees. At the beginning of the development process gait parameters are analyzed. Defined boundary conditions help to get the right technical parameters for a structured development process. During the following development process, different concepts for active driven knee prostheses are discussed. Essential components for active driven prosthesis systems are presented. The focus during the scientific work is the development of an active drive system for an active driven knee prosthesis. A first prototype of an active driven knee prosthesis is shown.
