PCT No. PCT/SE93/00718 Sec. 371 Date Mar. 3, 1995 Sec. 102(e) Date Mar. 3, 1995 PCT Filed Sep. 3, 1993 PCT Pub. No. WO94/06031 PCT Pub. Date Mar. 17, 1994Apparatus for the automatic fuelling of vehicles. A robot head that carries a fuel filler tube is movable to enable it to be brought into position to engage with a vehicle fuel-tank pipe. The robot head carries an opening device for opening a fuel-tank cover plate of a vehicle. The positioning of the robot head is effected by a positioning system that includes a transceiver unit carried by the robot head and that preferably operates at microwave frequency. A passive transponder is carried by the vehicle and includes a simple code which the transponder is intended to modulate on a signal transmitted by the transceiver and is reflected by the transponder. The signal received by the transceiver from the transponder is decoded and is used to access a robot head movement plan that corresponds with that code, to automatically steer the robot head to the fuel tank pipe and thereby enable the vehicle to be fuelled. |
