Abstract: Articulated industrial robots are widely used in modern industrial automatic production with their good flexibility and high efficiency, such as handling, palletizing, welding, cutting and so on. Trajectory planning is the basic research field of motion control on industrial robot, which determines the operating efficiency and movement performance. Trajectory planning of industrial robots combining operational requirements and robotic performance, guides the trajectory of end effector for robots in Cartesian or joint space. The concept and classification of trajectory planning of industrial robots are expounded in this paper. Various kinds of algorithms for trajectory planning are summarized comprehensively, including basic trajectory planning and optimal trajectory planning. The problems existing in various algorithms for trajectory planning and some future development trends are pointed out.
