Optimal planning of Robotic Trajectories
Proceedings of the 8th International Conference on Advanced Manufacturing Systems and Technology AMST '08, Udine, June 12-13 2008

Abstract: A technique for optimal trajectory planning of robot manipulators is presented in this paper: an objective function composed of two terms is minimized: a first term proportional to the total execution time and another one proportional to the integral of the squared jerk (defined as the derivative of the acceleration) along the trajectory. This latter term ensures that the resulting trajectory is smooth enough. The proposed technique enables one to take into account kinematic constraints on the robot motion, expressed as upper bounds on the absolute values of velocity, acceleration and jerk. Moreover, it does not require the total execution time of the trajectory to be set a priori. The algorithm has been tested in simulation yielding good results.
