Performance analysis of 3 DOF Delta parallel robot

Abstract

Parallel robots have inherent advantages for many applications in the fields of robotics. They offer high dynamic capabilities combined with high accuracy and stiffness. There are a lot of performance criteria which have to be taken into account and which are pose dependent. The main idea of this paper is to present the fundamentals for a performance evaluation of the 3 DOF Delta parallel robot. Therefore we discuss a large number of performance criteria dealing with workspace, quality transmission, manipulability, dexterity and stiffness.
