Make your disable button very, very big. And always have it plugged into the OI. Earlier today I had a robot start running away because the joystick was out of calibration... I was literally holding onto the transmission mount panel, and hoping that someone would come hit the circut breaker.
Last year I had the robot come full speed in reverse at me. That wasn't too fun.
I think I may want to put a large EStop button on the robot itself this year..just tell it in code to zero all pwm's when its pressed
