A system and method for determining relative positions of robots constrained to move along a common axis of motion, where a controller of the system has no prior knowledge of the relative positions. The robots are ordered to move in defined directions and distances and report their ability to move in the desired directions. From this information, a controller of the system can determine their relative positions.

Position determination of multiple mechanisms sharing a common axis of motion in a robotic tape library

A system and method for minimizing electromagnetic radiation emissions from a data cartridge handling library employs intermittent operation of the video camera to ascertain correct bin locations and verify automated access between bin locations. This intermittent operation is utilized when an error is suspected or upon a predetermined routine to verify manipulation accuracy.

Method and system for emission suppression in detection of data cartridge labels

An automated media library gathers information about each readable cartridge label using a camera. From the label information, the orientation of the cartridge may be determined. For each cartridge with an unreadable label or no label, the media library attempts a get/put operation. If the get/put operation fails, the cartridge is marked as incorrectly oriented. Alternatively, the tape library may attempt a get/put operation on all removable media cartridges. A similar process is performed when a cartridge access port is closed and the cartridge access port is marked inaccessible to the host when an incorrectly oriented cartridge is detected.
