Abstract: A calibration system for a robot and its peripheral includes an emitter attached to the robot or its peripheral and emits a laser beam and a receiver also mounted to the robot or its peripheral at a point to permit calibration and for receiving the laser beam and to permit calculations to determine the dimension between the emitter and the receiver.

Abstract: An improved system (20) for the calibration of a robot system. The system (20) comprising a linear displacement measurement device (32) in conjunction with a robot calibration system. The linear displacement measurement device (32) comprising an elongated member (34), a drum, a shaft, a drum displacement mechanism and a drum rotation sensor. The drum is displaced axially upon the shaft as the drum rotates when the elongated member (34) is moved. The drum rotation sensor provides accurate information regarding the distance the elongated member (34) travels. The displacement measuring device (32) is used in an iterative manner with the calibration system (20) for the purpose of the calibration of a robotic device (22).

Abstract: A system for calibrating a robot used for inspecting a workpiece to maintain the accuracy of the robot during inspection of workpieces on a production basis, the system including means for storing a mathematical model of the robot, means for measuring the position of a target and then calibrating the robot based upon input from the mathematical model and the position of the target.
