Cover Story: The accuracy and repeatability of motion in industrial robots are limited due to joint encoder resolution and uncertainties in the forward kinematics often used to drive applied control systems. To enhance motion precision, a high-resolution prismatic joint is integrated into the industrial robot, and a laser tracker is employed to deliver precise 3D end-effector position feedback to the overall system. The position feedback is then processed using a multilayer perceptron neural network control algorithm to increase the positional accuracy of the system. Statistical tests conducted on selected points from an ISO 9283 trajectory based on 30 measurements demonstrate an 82% improvement in position accuracy using the proposed approach over the original industrial robot controller.
