As most of the people at UCF can probably testify to, we were one of the fastest 'bots there, and the more I think about it the more I think that may have been our problem. We could easily stall the motors by putting our robot against a wall and we occasionally managed to do it while turning.
As Andy144 said, we had many fewer problems by Saturday. My guess is that our treads finally got worn down enough to the point where they would start slipping before we reached stall torque.
As a side note, it got to the point where we replaced the 40A breakers after every round, just to be on the safe side. This eliminated many of our problems, but we did still trip the 120 once more. Unfortunately, our 120 wasn't exactly in an easy to replace position, so we couldn't really change it out easily.
Side note #2: does anyone have any data on how much current it takes to trip the 120? Last year I remember FIRST releasing a spec sheet on the 60A stating that you could easily put 110A through it for a short time without tripping it. Was there something similar this year?
