6.5 Calibrating with Wrist Optimization method
When to run Wrist Optimization
Wrist Optimization routine is run to improve TCP reorientation performance.
Calibrating the robot with standard calibration method overwrites the optimized
positions of axes 4, 5, 6. Re-run the Wrist Optimization routine after standard
calibration to re-achieve the optimized positions of the wrist axes.
Overview of the calibration procedure on the FlexPendant
The actual instructions of how to perform the calibration procedure and what to
do at each step is given on the FlexPendant. You will be guided through the
calibration procedure, step by step.
Use the following list to learn about the calibration procedure before running the
RobotWare program on the FlexPendant. It gives you a brief overview of the
calibration procedure sequence.
After the calibration method has been called for on the FlexPendant, the following
sequence will be run.

1 Choose calibration routine Wrist Optimization.
2 Modify targets for 4-point tool frame definition, in Wrist Optimization routine.
Tip
Select positions with large reorientations around the TCP. For best results,
make sure that axis 4 and 5 have large movements.
a Jog the robot to an appropriate position,
A, for the first approach point.
Use small increments to accurately posi-
tion the tool tip as close to the reference
point as possible.
b Tap Modify Position to define the point.
c Repeat for each approach point to be
defined, positions B, C, and D.
Jog away from the fixed world point to
achieve the best result. Just changing the
tool orientation will not give as good a
result.
3 Improved calibration data to the wrist axes is identified and presented.
4 Optimized positions for the wrist axes are presented.
