Robot calibration is the process of identifying the real geometrical parameters in the kinematic structure of an industrial robot, i.e., the relative position and orientation of links and joints in the robot.

A calibrated robot has a higher absolute positioning accuracy than an uncalibrated one, i.e., the real position of the robot end effector corresponds better to the position calculated from the mathematical model of the robot.

Absolute positioning accuracy is particularly releveant in connection with robot exchangability and off-line programming of precision applications.

Besides the calibration of the robot, the calibration of its tools and the workpieces it works with can minimize occurring inaccuracies and improve process security.
