L40 and L80
In the L40 and L80, the robot, behind the front door, consists primarily of the:
•
Theta assembly for lateral movement
•
Z drive assembly for vertical movement
•
Hand to mount and dismount cartridges
Most of the robotic components are mounted on the Z shaft. The hand on the Z carriage
moves up and down the shaft to access the cells. The cells are stacked in columns; the
columns are arranged around the robot. The hand rotates about the shaft.
The camera, on the hand, reads the bar code volume serial numbers on the cartridges,
and the library and CAP calibration targets.
