1. Apparatus for automatically refuelling vehicles, primarily cars, said apparatus comprising:

  • a robot which includes a robot head that is movable relative to said robot to enable the robot head to be brought from a rest position to a predetermined position relative to a vehicle fuel-tank pipe, wherein the robot head includes an outer tube and an inner tube housed within said outer tube and movable axially out of said outer tube, wherein the outer tube is adapted to be docked with an adapter attached to an inlet orifice of the fuel-tank pipe so that subsequent to docking of said outer tube, a free forward end of the inner tube is extended into the fuel-tank pipe to deliver fuel through the inner tube and into the fuel-tank pipe, the robot head including a fuel-tank flap opening device to open a fuel-tank pipe cover flap in response to movements of the robot head, an optically readable movement plan code carried on the vehicle, a robot head positioning system including a computer having a memory for storing a plurality of movement plans corresponding with respective movement plan codes, wherein the computer is programmed to control the robot head to carry out a movement plan corresponding with an optically-read movement plan code after receiving said code, the positioning system including an optical sensor disposed adjacent the robot for detecting optically the position of the fuel-tank flap of a vehicle parked for fuelling purposes, relative to the rest position of the robot head, wherein the optical sensor senses said movement plan code, and wherein the computer is adapted to guide the fuel-tank flap opening device into abutment with the fuel-tank flap and to open said flap and effect said docking in accordance with said movement plan, and also to carry out said movements in reverse order and thereby close the fuel-tank flap when fuelling has been completed.
