Science Nation: Cars Without Drivers

Meet Boss - the car that can drive itself! Boss is the invention of Carnegie Mellon researcher Raj Rajkumar and his team. It has 18 sensors, including a three dimensional laser and onboard computers that connect to GPS and mapping software. When it comes to knowing the rules of the road, Boss rarely makes a mistake. With support from the National Science Foundation, it was built for a Department of Defense competition called the DARPA Urban Challenge. Boss negotiated the roads, including traffic, and was the hands down winner in 2007.
