- Abstract
This paper presents the kinematics analysis of a 3-RRR(4R) parallel mechanism. A new approach of motion planning based on the planned trajectory is proposed and demonstrated on parallel mechanism 3-RRR(4R). Both forward and inverse kinematics relationships are derived. Based on the structure analysis and inverse kinematics analysis of the parallel mechanism, the movement law of the three input motors can be derived from the equations of the planned trajectory. The approach is verified by simulation results, which are consistent with the planned trajectory. Coupling analysis was performed for the output–input of the parallel mechanism and was significantly simplified by using the simulation software relative to the conventional mathematical method.
