If a central control system controls one or more AGV (Automated Guided Vehicles), one speaks of a AGS (Automated Guided System). The AGVs consist essentially of one or more driverless transport vehicles, a guidance control system, equipment for location determination, position detection and data transmission, as well as an infrastructure and peripheral equipment. A driverless transport vehicle is also subject to the scope of the Machinery Directive in the European Economic Area.
