Stack bases are used to accurately place the stack and racks in the work area of the robot.
The stack bases are mounted with a sprung loaded clip that ensures that the racks/stacks are located correctly, and therefore can be accessed by the robot reliably.
The stack bases can be fitted with a number of modifications:
- blue lights that confirm that the rack/stack is located correctly (blue light on = correctly located)
- switches that have a signal that can be fed back to the controlling computer for Overlord3 to determine that the rack/stacks bases are located correctly.
