Abstract

A method for real-time three-dimensional control of position and attitude of an end effector of a manipulator relative to a moving workpiece. Angles of revolute joints of the manipulator are controlled by harmonizing a first control methodology, wherein the z-axis coordinate of the end effector and the attitude of the end effector are controlled based on input target values for the position and attitude of the end effector, with a second control methodology, wherein the x-axis and y-axis coordinates of the end effector are controlled responsive to image data captured by a camera mounted to the manipulator.
