Um...Really? Here are a couple of reasons why *we* don't let the motor run. I'm not sure what Mr. Neun's reasons are.

1. Don't want to stall the motor. Stalling the motor = BAD. During the finals at Palmetto, our sensor wasn't tripping as well, and the window motor was stalling. We could smell it from the drivers station. 343 was nice enough to spray their freezing blast onto our window motor before each match, or we would've been more toast. (pun intended )

2. In some instances with a particularly-not-well-inflated ball, the ball will get sucked into the robot further than 3". (That is of course if you're not using a hard backing). Which, if you are facing a physical backing, then you'll more than likely stall the motor, and then you're back to reason 1.


Our method is that the backing for the ball is hinged, so when the ball comes in, the backing goes in with the ball. And then at the appropriate 3", the backing trips a switch, which turns off the motor.
