Champion Robot Car Declared

 Carnegie Mellon's computer-laden Chevy Tahoe wins the Urban Challenge and takes home the $2 million prize.

 In the 1880s, the carriage lost its horse. Now, thanks to a car named Boss, the automobile could be about to lose its driver. This weekend, Boss, a Chevrolet Tahoe fitted with sensors and computers by a team of engineers from Carnegie Mellon University, won the most famous of robotic races: the Urban Challenge. With no human assistance, the vehicles competing in the race had to safely and quickly navigate city streets while staying in their lanes and avoiding other moving and parked cars. With the win, the Carnegie Mellon team, called Tartan Racing, takes home a $2 million prize from the U.S. Defense Advanced Research Projects Agency (DARPA), the organization that sponsored the race. The $1 million second-place prize went to Junior, Stanford University's robot; Odin, Virginia Tech's bot, came in third, winning $500,000.
