1.6.3 Absolute Accuracy calibration

Purpose

Absolute Accuracy is a calibration concept that improves TCP accuracy. The

difference between an ideal robot and a real robot can be several millimeters,

resulting from mechanical tolerances and deflection in the robot structure. Absolute

Accuracy compensates for these differences.

Here are some examples of when this accuracy is important:

The option Absolute Accuracy is integrated in the controller algorithms and does

not need external equipment or calculation.
