Story highlights Germany's Dusseldorf airport has installed a robotic parking system called RAY

It can be controlled via an app and retrieves cars based on flight arrivals data

It can park 60% more cars than a human operator and costs $5.50 an hour

(CNN) Throwing your keys at the parking valet as you sashay onto a flight may seem like the stuff of James Bond films, but already a robotic valet is taking the sweat out of getting on a plane at Germany's Dusseldorf airport.

Rather than getting behind the wheel, however, this robotic valet physically lifts your three tons of road machinery and slots it into pre-designated robot parking bays.

Nicknamed RAY by its creators, the automated forklift truck is the brainchild of Germany's Serva Transport.

Aimed at business travelers in a hurry, the automated parking system can be controlled and booked via an app. All travelers have to do is drop the car off in a designated area, go to a nearby touch screen to confirm the car is empty, and RAY does the rest.

RAY uses sensors to measure and photograph the car, it then gently lifts it and takes it to one of 249 parking spots reserved for the robot forklifts.
