The 2007 DARPA Urban Challenge represents a new frontier in autonomous vehicle technology. We were live onsite for the final of this year's event, which saw 11 robot cars compete in a six-hour contest in a simulated urban environment, complete with traffic, intersections, and parking lots. The rolling robots varied from a driverless 12-ton Oshkosh truck to an autonomous Toyota Prius. Check out our video diary from this weekend's event.
