Parking cars appear to be one of the problems solved in Düsseldorf airport where a robot called RAY working hard to provide the best parking service inside the airport. The travelers have to leave their car in a specific area and confirm using a controlling kiosk that the car is empty and ready to be parked. The robot lifts the car and let it on one of the 249 parking spaces reserved for the premium parking valet.
To take back the car, you have to call the robot valet using a simple smartphone application.
RAY can park safety any standard car with a maximum weight of 3.3 tons. Any premium service has premium prices. Opened for everyone, this service will cost travelers up to 29 Euros ($39.43) for only one busy day.
