DARPA's Grand Challenges have already helped put plenty of self-driving cars on (closed) roads, but it looks like the agency has something a bit different in mind for its next one. As first reported by Hizook, DARPA has apparently set its sights on humanoid robots as its next target -- specifically, robots that are human-like enough to navigate rough terrain, drive a vehicle and manipulate regular tools (the idea being to simulate assisting in an industrial disaster zone). What's more, participants will have to develop robots that can do all of that "semi-autonomously," with only "supervisory teleoperation" permitted. No word on a timeline for the challenge just yet, but DARPA will apparently have more to say when it makes things completely official within the next few weeks.

It looks like DARPA's newly-instated Urban Challenge is shaping up nicely, with this self-driving Isuzu SUV from Austin Robot Technology and the University of Texas now joining the likes of Team LUX's Volkswagen Passat and NC State's Lotus Elise in competing for the top prize. As with those other vehicles, the SUV (dubbed Marvin) is completely autonomous, relying on an array of sensors, video cameras, artificial intelligence, and machine-learning technology to (hopefully) avoid catastrophe as it motors about. As you might guess, the Urban Challenge presents a few different obstacles for the vehicles to deal with than the Grand Challenge does, including intersections, improperly parked cars, and traffic laws that must be followed at all times. Marvin still has a ways to go before it can get a chance to drive away a few million dollars richer, however, with it required to pass a basic driving test this summer and a national qualifier in October before it's allowed to enter the big event in November.
