Grand Challenge Update

We're only two hours into the Grand Challenge, and it's already not looking good. One team (Team TerraHawk) has withdrawn, and seven robots are now listed as disabled, including Carnegie Mellon University's roboticized Humvee which was considered the odds-on favorite. Team DAD, which entered a driverless Toyota pick-up (pictured), has managed to get the furthest of any of the robots — about six miles.
