METHOD FOR CALIBRATING ROBOTIC PICKER MECHANISM IN AUTOMATIC STORAGE LIBRARY SYSTEM, ROBOTIC MECHANISM FOR TRANSPORTING STORAGE DEVICE, AND STORAGE LIBRARY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method and a system performing discrimination more accurately and/or with smaller mark about accuracy of a position of a robotic mechanism in an automated storage library.;SOLUTION: In one aspect and one example, a method for calibrating robotic picker mechanisms in automated storage library systems includes a step in which a calibration mark is detected with at least one sensor from a first position and a second position, where the first position and the second position are separated by an offset distance. Further, this method includes a step in which a shift in the calibration mark between the first position and the second position is determined and a step in which distance between a reference position and the calibration mark is determined based on the shift in the calibration mark, the offset distance, and the focal length of the sensor.;COPYRIGHT: (C)2005,JPO&NCIPI
