Automatic calibration method for robot systems using a vision sensor

摘要

An automatic calibration method for a robot system is disclosed. The automatic calibration method for a robot system includes the steps of calibrating a sensor and a sensor coordinate system of the sensor with respect to a world coordinate system, controlling a robot under the guidance of the sensor to move a point of a tool mounted on the robot to reach a same target point with a plurality of different poses, the point of the tool in a tool coordinate system, and calculating a transformation matrix ^tcpT_t of the tool coordinate system with respect to a tool center point coordinate system based on pose data of the robot at the same target point.
