Subsequently, the third ‘hand’ grabs the fuel nozzle, inserts it in the fuel slot and fills the reservoir. Afterwards, the fuel nozzle is put back in its position, the robot screws the cap back on and shuts the fuel valve. The robot retreats behind the sliding wall, and the instruction display indicates that the car is ready to depart. The driver checks out without having to exit the car.
