Up to 16 LSMs can be interconnected. Cartridges can be passed from one LSM to
another through a pass-thru port/cartridge exchange mechanism (PTP/CEM) in the
walls of adjacent LSMs. If a cartridge is in one LSM and the assigned transport is attached
to another LSM, the robot retrieving the cartridge from its home cell places it into a
PTP/CEM. The robot in the adjacent LSM retrieves the cartridge from the PTP/CEM
and mounts it in the assigned transport, or places it into another PTP/CEM to continue
passing the cartridge to the destination LSM.
When a mount is requested:
1. The servo system moves the robot fingers to within 0.65 cm (0.25 in.) of the center
of the cell location.
2. A solid-state camera vision system fine-positions the robot fingers.
3. The camera makes sure that the VOLSER label on the cartridge is correct.
