Elements of Synthesis and Experiment for Parallel Robots

Parallel robots have received special interest due to their advantages over conventional serial mechanisms: high rigidity, high load capacity, high velocity and high precision. The parallel robot is a mechatronic system and requires to be designed in the spirit of the mechatronic philosophy. The use of a parallel robot in a given application requires a careful analysis of the structure and of the indispensable parameters. Structural synthesis of mechanisms for parallel robots is addressed in detail. This paper proposes a method of structural synthesis of the parallel robotic mechanism according to the concept of the mechatronic philosophy and of the kinematic connections. The authors offer a system for analyzing the robot performances based on the3D CompuGaugeequipment.
