Robotics Unit

The robotics unit provides movement of cartridges among the storage slots, tape

drives, and cartridge access ports (CAPs). The three main robotic components are:

Z drive assembly

X table assembly

Hand assembly

The Z drive assembly uses the Z drive pulley to move the X table up and down to the

desired slot or tape drive. At the same time, the X carriage assembly (containing the

hand) moves the hand forward and backward; the wrist motor rotates the hand right

and left.
The hand assembly contains the wrist hub assembly, gripper assembly, and bar-code

scanner. The gripper assembly has fingers that grasp the sides of the cartridge. If the

library loses power while a cartridge is between the fingers, the manual release screw

is used to remove the cartridge. A worm gear can be used to rotate the hand to the

correct position to access the manual release screw.
For safety purposes, the robotics will be parked in the robotics unit when the front door

is opened or when the

Open Door

button is pressed on the keypad. Parked means

that the robotics components are fully retracted into the robotics unit at the top of the

library. To verify the robot is parked, look at the lever in the cutout beneath the facade

and to the bottom left of the keypad, the lever should be to the left.
The robotics unit is accessible from the front of the rack.
