Parallel robot, called Parallel Mechanism in English, or PM for short, can be defined as a moving platform and a fixed platform connected by at least two independent kinematic chains. The mechanism has two or more degrees of freedom and is driven in parallel. Closed-loop mechanism.Parallel robots are characterized by no cumulative error and high accuracy; the driving device can be placed on or close to the fixed platform so that the moving part has lightweight, high speed and good dynamic response.
