After 2 regional events, we have found that our color coded bumpers have been very effective. They are easy to see and they are fairly easy to swap, however, in both events we did not have enough time to change them out in any of the quarter-finals, semis or finals matches. We were busy making sure that the robot was totally functional. That is why we decided to do two red and two blue bumpers for the eliminations. Our bumpers were always highly visible in every match. There were plenty of matches where we were gently persuaded
by one or more opponents in a "robot pile up" but one could still discern our robot by its bumpers. However, I am not totally convinced that our color coded bumpers are the best solution. We'll see how they do in Atlanta next week.
