Carnegie Mellon wins the robotic Urban Challenge
Stanford relegated to second
Carnegie Mellon University has redeemed itself by winning the $2m first place prize in the DARPA Urban Challenge. Stanford University took second and $1m, while Virginia Tech took $500k for third.
Six vehicles of the 11 vehicles finished the sixty-mile course with Stanford, Carnegie Mellon and Virginia Tech all closing within a few minutes of each other. The robots had to complete a number of different missions, returning to the starting point each time to collect a new task. Meanwhile, teams from University of Pennsylvania, MIT and Cornell finished as well, although after the alloted six-hour limit.

Individual winner aside, the contest proved a success for DARPA and for the advancement of robotics technology. Just three years ago, similar vehicles failed to travel more than a handful of miles along a desert course. In that race, the systems were hand-fed GPS points and needed only focus on speed while avoiding stationary targets such as ditches and trees. One year later, the vehicles mastered those tasks but were unprepared for facing more demanding tasks.
Stanford won the second race, beating out a pair of vehicles produced by longtime robotics powerhouse Carnegie Mellon. The Stanford victory proved tough for Carnegie Mellon to swallow since the Stanford team is led by Sebastian Thrun - a former student of Carnegie Mellon lead Red Whittaker. This time Red got his revenge.
In addition to the money, the winning teams received cheesy, giant eagle statues.
Carnegie Mellon had to overcome a bit of adversity to take the victory. A jumbotron screen near the starting line crippled its GPS receivers. So, Carnegie Mellon had to replace its receivers and started about thirty minutes late.
DARPA officials said that Carnegie Mellon averaged about 14 mph with Stanford and Virginia Tech slightly under that.

Over the span of two years, the university teams have been the ones to show the most progress. Boosted by millions of dollars in government and corporate aid, the academics have crafted systems that can share the road with human drivers. The robots know how to take their turn at a four-way stop. They know how to follow traffic laws such as flashing their indicators when passing a slower car, and they can, for example, mimic the task of taking off from a garage to pick up a jug of milk and then return home.
Would these robots fare well on the busy streets of a real city? No.
In fact, even the winning teams suffered from the repeated stops and starts generated by confusion. Some cars would perform great, weaving through one way streets and intersections only to come to a complete halt in the middle of an open road.
Happy Carnegie Mellons
We'll be damned though if the day when you could flip your car into automatic mode while stuck in bumper-to-bumper traffic isn't far off. You'd still be lodged in the hell that is rush hour, but at least you could watch some TV or read a book during the process.
Such a practical use of robotics technology could serve as a great boon for an industry that has relied more on fantasy than practical application for its charming aura.
DARPA too benefits from this endeavor. The agency looked the clown in 2004 when it bumbled through the Grand Challenge, allowing too many teams to participate, changing rules at a whim and celebrating a $1m first-of-its-kind race that resulted in a stream of negative press reports.
The organization must look better in the eyes of Washington officials now that it's figured out how to control the qualification events and overall structure of the race to almost ensure some sort of victory.
Six teams finishing this more complex event beats out the five finishing the 2005 challenge by a significant margin.
DARPA used various criteria to determine the winner, looking at how quickly the robots completed the course and how many traffic violations they endured. The organization collected this data from the vehicles and by watching the robots from the sky with an airplane. That plane sent back video with up to .5m resolution of the event, allowing officials to replay incidents in slow motion as needed to determine who was at fault.
Still, some of the criteria seemed iffy. For example, vehicles were punished if they were caught in traffic caused by another vehicle, since that would replicate real life circumstances. We saw Stanford's car Junior suffer as Cornell delayed for 10 to 20 minutes.
Weird Victorville drink called Chelada. Beer and Clamato - Ew.
DARPA officials revealed the winners during a ceremony today here in Victorville, California - a small town outside of Los Angeles.
Will there be another Grand Challenge? Maybe not. The government has taken away DARPA's ability to offer cash prizes for these types of events without federal approval.
"I don't know why they did it, but they did it," DARPA Director Anthony Tether said. "I don't have the authority to say, 'Yes'.
"We never really finish anything (at DARPA). We just show that it can be done. We take the excuse off the table. I think we are close to that point. "
Red Whittaker has called for something like a 24-hour race that force the vehicles to deal with different terrains, weather and day/night conditions.
According to Thrun, these events prove crucial to US technology development. They help encourage youngsters' interest in robotics.
"We are going to build a whole new student force for the next thirty years to come." ®
