Aspects on Synthesis and Modeling of the Parallel Mini-robots and Micro-robots

All over the world it can be noticed that the 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 raise of the positioning accuracy by the use of parallel structures. The progress of the industrial production, especially the development of the industrial robotics is more and more based on a new generation of robots based on closed kinematic chains mechanisms, the parallel robots. In the paper are presented a structural synthesis of the parallel robots which leads to some variants of parallel mini-robots and micro-robots with different degrees of freedom. These parallel robots are used for manipulation within the high precision assembling processes. Some parallel robots were developed the geometric virtual models by using the Solid Edge virtual modeling software packages. Based on the corresponding geometric models, the modeled solutions are developed with classical joints and with pseudo-elastic joints.
