Perform the following:
1. "Removing a Drive Sled" on page 8-43
2. "Replacing a Drive Sled" on page 8-44
Calibration completes and the coordinates of each storage and I/O element
are calculated. The calculated values are determined to be outside travel
limits that have been established for the robot.
Calculated element positions fail validity check against travel limits.
1. Calibration targets not in position.
2. Calibration sensor detects edges but is not correctly finding calibration
target edges.
