Re: Interesting Q/A's

This one bugs me a little, because of the reasonably elegant solution that the team has proposed, and the silly response that was received:

There would be no exposed wiring that would be cause for concern of a short. These additional leads on the motor would not be connected during the match. The RC car battery will always be kept charged and be kept with the driver and never installed on the robot.

Who hasn't connected a battery directly to a motor, to advance it, or to test it? The match is over, let the team do as they see fit—it's absolutely clear in the question that there is no possibility of the extra battery being used in a match, and it seems unlikely that the extra battery will hinder efforts to remove the robot from the field—indeed, it appears to do quite the opposite.

Of course, the best solution would be to design a system which doesn't need any extra power to release balls....
