Absolute Accuracy Calibration - ABB IRB 1200 Product Specification

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.
