Enevitable- Trackball popped

[ALIBI]

Has anyone out there had a practice match with six robots on the field? The kids have abused the trackball in our shop and have not managed to pop it. We have moved it around with proto-types etc. etc. and never had a problem. However, now that the robot has come together, the very first time the trackball was at a height at or above the overpass, when it came down onto another robot, well, let's just say, where's the repair kit? Looking at the videos of several launchers, if the trackball were to hit a robot instead of the floor/wall, things that are safe for human contact on the robot may become hazards for the trackballs. Simply rounding metal corners etc. may not be enough to protect the trackball in competition.
