  • ROBOT CALIBRATION SYSTEM AND CALIBRATING METHOD THEREOF
    Publication number: 20110320039
    Abstract: A robot calibration system includes a robot, a calibration tool, a plane calibration board, a camera, and a controller. The calibration tool is assembled to the robot and is controlled by the robot to move along a preset trajectory. The plane calibration board is located under the calibration tool and has a plurality of characteristic corner points on one surface thereof. The camera is configured for capturing an image of the plane calibration board. The controller electrically connects with the robot and the camera respectively, the controller predefines a preset control program for controlling the robot and the camera to operate, and the controller is configured for calibrating the robot. The disclosure also discloses a method for calibrating a robot for use with a robot calibration system.
