Robot collision avoidance control using distance computation
Jih‐Gau Juang · 2002
Control of robot collision avoidance is studied. A repulsive force is artificially created using the distances between the robot links and obstacles which are generated by a distance computation algorithm. Control gains are selected w.r.t. the ranges of the angular velocity and angular acceleration of a PUMA 562 manipulator. In this paper, the computational time of the distance computation algorithm has been proved to be acceptable for robot collision avoidance applications. Two two-link robots are assumed in simulation. The control scheme is able to drive these robots to their destinations without collision.
