The Arcom Luggage Control System is a functioning model using Fischertechnik Construction Blocks.  The model is comprised of two conveyer belts, joined in an “L” shape.  Each belt is driven by a dedicated motor, a vertical “scanner” driven by a third motor and a pusher device by a fourth.  An object travels along the first belt, is “scanned” and then is moved onto the second belt by the “Pusher”.  The purpose is to simulate a full-scale luggage conveyor system deployed in many airports.  The Arcom Luggage Control System’s user interface can be found here.
