I went to this http://feh.osu.edu/competition.htm
tonight. Quite fun! My girlfriend's son was participating. Lessons learned... don't change your environment on the last day of testing. They had a robot built that was working great and they had been downloading the software via one of the campus machines. Today, all the sudden it started misbehaving? Why? Not sure, but they started using one of their own personal laptops and the thinking is one of the libraries in their environment that it downloaded to the robot was outta synch. Their robot stalled after driving forward about 2 inches (the GPS data got all whacked). We were sorry to see that happen, since his robot had performed quite well in the preliminaries.
I use to participate in a Lego Robotics League with a bunch of guys at AOL. I kind of miss those days. We had some great competitions and some great innovation. Sometimes I wish I had gone into robotics, since whenever I play with it, I seem to do pretty well and really enjoy it.
