On highways of California, Google started testing robot cars, in order to map the streets. So far seven cars are on the road and the have completed 140,000 miles with rare human intervention. The car finds its way through a rotating camera at the top which continuously creates a 3D view of the car’s environment, as well as motion sensors and a front camera in the front which spots the other moving objects or people. There are also GPS devices on the car which helps the navigation. The autonomous car concept had been tried and tested in DARPA grand challenges before, which was a competition of robot cars.
