TRAJECTORY OPTIMIZATION ALGORITHM FOR A 4-DOF REDUNDANT PARALLEL ROBOT BASED ON 12-PHASE SINE JERK MOTION PROFILE

Trajectory Optimization Algorithm for a 4-DOF Redundant Parallel Robot Based on 12-Phase Sine Jerk Motion Profile

To improve high motion Thermo Actuator accuracy and efficiency in the high-speed operation of a 4-DOF (4 degrees of freedom) redundant parallel robot, this paper introduces a trajectory planning of the parallel robot in joint space based on the twelve-phase sine jerk motion profile.The 12-phase sine jerk motion profile utilizes the characteristics
