Similar to an old conveyor system on an Eshed Robotech system. There were 5 bits for each carriage encoded using magnets which rode the conveyor giving you 32 addresses. As the carriage passed into a station a pneumatic cylinder extended to trap it so it would stop above the sensors. If that carriage was to be processed at that station it would be picked off by a robot and placed in a dock.
