Self-driving cars: Where do they go from here? (pictures)
The road to the future is unmanned. Here are some of the robo-vehicles that have helped to pave the way.
Google's self-driving car
One of Google's self-driving cars maneuvers through the streets of in Washington, D.,C., in May 2012. The system on a modified Toyota Prius combines information gathered from Google Street View with artificial intelligence software that combines input from video cameras inside the car, a LIDAR sensor on top of the vehicle, radar sensors on the front of the vehicle and a position sensor attached to one of the rear wheels that helps locate the car's position on the map.

Stanford's self-driving Audi TTS, Shelley
Stanford's self-driving Audi TTS, Shelley, hit 120 mph on track test seen here in August 2012. Using new research on professional drivers' brain activity, Stanford hopes to improves the car's self-driving abilities.
A 2006 Volkswagen Passat Station wagon diesel, heavily modified and robotized by a team from Stanford University, begins the second stage of the DARPA urban challenge in Victorville, California on November 3, 2007.
