New development of parallel robots and microrobots with three, four and five degrees of freedom

Abstract

Abstract All over the world it can be noticed that product miniaturisation is a central theme in product development for different application areas. In robotics scientific research, one of the most important approaches is concerning the increase of the positioning accuracy by the use of parallel structures [3], [4], [5]. In this paper some variants of parallel robots and micro‐robots with three, four and five degrees of freedom are presented, which are used for manipulation within high precision assembling processes. The corresponding kinematic models have been developed. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
