Automated guided vehicle robot “Ray” lifts up an Audi car during a pilot project at the parking area of the Audi plant in Ingolstadt, Germany, May 13, 2015. The robot has been designed to help make work more efficient and more comfortable for employees, some whom walk up to eight kilometres a day, while coordinating the finished cars for the subsequent train transportation. “Robot Ray” technology, currently being used at Dusseldorf International Airport in Germany, claims to be able to park 60 per cent more vehicles in one area compared with a human driver.
