This would be a great robot to enter in the Intelligent Ground Vehicle Competition (IGVC). This competition is sponsored by DARPA and is similar to the Grand Challenge though on a smaller scale. The website for the competition is
www.igvc.org. The website is down right now, but hopefully it will be back up soon. The competition has two main challenges: the autonomous challenge and the navigation challenge. In the autonomous challenge, the robot must drive between two white lines painted on a grass field while avoiding traffic cones, barrels, sand traps and other obstacles. In the navigation challenge the robot must drive to some GPS waypoints. There are fences, traffic cones and other obstacles in the way. The competition is May 30-June 2, 2008 at Oakland University in Rochester MI. If you throw a LiDAR or sonar array, video camera, and some hardcore software on that robot you will be good to go. I am on the IEEE Robot Team at UW-Madison and this is the main competition we enter in. You can check out our team website at
