422's pit stops
We actually have a sturdy 'bot, so we're not always doing repair jobs and the like. But this is usually the routine:
Before a match:
1) Run a systems check to determine if both drives can move easily and the goal grabber... grabs.
IF (systemscheck == good)
{
2) Sit around for 10 or 15 minutes because we did the check
far too soon.
}
else
{
2) Scramble like mad to tighten things, crimp things, electrical
tape things, and wire-tie things to state of functionality
}
After a match:
1) Pick up the panels that have fallen off the robot and onto the field. Try to rub off the tire marks left by other robots driving over them repeatedly. Replace panels by leaning them against the robot and velcroing them back down.
2) Call down our engineer and reassure him by saying "The drive train still works, no chains popped, the motors are cooling, everything will be all right"
3) Run another systems check and fix whatever electrical problems we might have. Mechanical has never broken down (goal grabber and the motor mounts/chains/motors themselves have never needed serious adjustment)
That's about it. The only serious problem we've ever had was our left drive random stopped working electrically one match, and when we took it back to the pits we found 3 different reasons the circuit couldn't complete on it (PWM cable, victor-to-plug wire, plug-to-motor wire).
