Absolute Accuracy option is integrated in the controller algorithms for compensation
of this difference and does not need external equipment or calculation.
Absolute Accuracy is a RobotWare option and includes an individual calibration of
the robot (mechanical arm).
Absolute Accuracy is a TCP calibration in order to Reach (m) a good positioning in
the Cartesian coordinate system.
