To nhill95 and others having issues,
Please, if you think you're experiencing a problem, take note of all of the LEDs on your joystick at the time of the problem AND look at the LEDs on the alliance field controller (the black box that your joystick connects to on the field). Provide this information when reporting a problem. Also, please indicate what was happening with the other robots on the field - were any of them nonfunctional as well?
We need more information than "our robot stopped working" to help you diagnose your problem. Thanks!
