Novel solutions for actuation of an above elbow prosthesis

Abstract

The above elbow prosthesis must provide the movement of the elbow, which naturally is composed by a flexion – extension movement. The mechanical system must fulfil a set of conditions regarding kinematics, dynamics, precision, size and load. The paper describes two novel solutions to generate the flexion – extension movement of the elbow. The description contains the kinematic scheme, elements of calculus and the CAD generated constructive solution.
