only one button? "Launch" or "shoot" would be good.

"Fire" on a robot is usually a bad thing - or do you mean to trigger the Halon system?

BTW: over the years I have seen robots catch fire during a match. Sometimes a motor does a pyrotechnic show billowing smoke. A few times wires have shorted and circuit breakers where not where they should be and stuff caught fire.

If this happens quickly look in the bleachers. You can actually see all the team scouts, crossing that team number off their list of potential alliance partners :^)
