ABSTRACT:
The positioning of a robot accessor in an automated data storage library is rezeroed with respect to a home position which potentially avoids moving the robot accessor to the home position in every rezero operation. The robot accessor is moved to the expected location of a reference point in the library. If the reference point is sensed by a robot accessor sensor at substantially the expected location, the rezero operation is completed; else, the rezero operation is continued. Alternatively, if there is an offset between the sensed location of the reference point and the expected location, the robot accessor is moved to a second expected location of a second reference point. If the offsets are consistent, the calibration is updated, completing the rezero operation.
