Picker
The picker moves the cartridges from one location to another. One motor rotates 
the picker platform to position the picker arm in front of the drive, mailslot, or 
desired magazine. Another motor positions the picker arm to retrieve or replace 
the cartridge. The rotation motor engages the arm on a notch of the cartridge, and 
the translation motor moves the cartridge from the picker to the drive (or 
magazine or mailslot) or from the drive (or magazine or mailslot) to the picker.
