Car terminals might well prove to be a future test ground for autonomous security and inventory robots. Equipped with navigation, RFID, communication and sensor modules the robots cooperate with each other and a central mission control. Continuously patrolling the terminal vehicles are identified while passing them (using RFID), their position established (using GPS or Galileo) and security relevant anomalies are recorded and transmitted (using cameras, sensors). The design of the robots provides for both active and passive damage prevention.
