IRV (Indiana's Robotic Vehicle) has still not completed the entire course after a second attempt today, but he improved significantly from yesterday's run. Flawlessly through the 35 foot long tunnel, then successfully past several more obstacles, but stopped by an old car placed on the course when he didn't quite get turned fast enough. He had slowed to maneuver around the car so the only damage was a busted tail light on the junker.
According to preliminary scoring IRV is about in the middle of the pack with more improvements expected and several more course runs scheduled (each team is supposed to get 6 scored runs).
As others have said, more info (including an informative brochure) is available at
