In the beginning of one of our matches, our human player accidentally threw a ringer onto our robot's team designation flag. We drove around for a little while trying to defend. (because we couldn't legally pic up another tube) About a minute in, the tube got stuck under our wheel... And jammed up our drive train. Our driver continued to try to break free but could not.
At the end of the match, when he was trying to remove the tube from the robot so that he could remove the robot from the feild, he said the tube looked like someone shot it with a shotgun. The friction from the wheel had melted a huge hole in it.
