Optimal Motion Planning for Robotic Manipulators

Abstract

This paper presents a time-optimal path planning scheme for a robot manipulator to track a specified geometric Cartesian trajectory. It considers actuator constraints, the full robot dynamics. In order to make full use of the motors capacity, the bound torques are determined by considering the bound of the generated heat. The velocity limit and the bound acceleration (deceleration) are determined by combining with dynamics. We utilize the phase plane analysis technique to generate the minimum time trajectory.
