Photos: Robot race in 'DARPA city'

The Defense Advanced Research Projects Agency, or DARPA, raised the green flag Saturday on 11 driverless cars to maneuver through a 60-mile course at the former George Air Force Base in Oro Grande, Calif., or what race officials dubbed DARPA city. It was part of DARPA's $3.5 million robot race, the Urban Grand Challenge.

Stanford's robot, Junior, was the first to cross the finish line in Saturday's Urban Grand Challenge, a six-hour test of autonomous vehicles with three separate missions. But the robot ultimately lost to Carnegie Mellon University's driverless car, Boss, which was faster overall.

Carnegie Mellon's team, Tartan Racing, won the $2 million first prize. Stanford took second place and snagged $1 million.

Correction: The length of the course was listed incorrectly. It was about 60 miles.
