Visitors of Dusseldorf airport in Germany no longer have to worry about parking their cars. A robot valet named Ray will do it for them.
Ray began working this week, and those traveling through Dusseldorf can book his services through a smartphone app. People simply have to leave their cars in the designated area and confirm it's ready to be parked. Ray will then take the car to one of the 249 reserved parking spaces.
The robot valet works like a forklift and carries standard-sized cars to vacant spaces. The cars must weigh less than 3.31 tons and be fully insured.
Ray's services cost 20 euros ($39.43) a day.
