The easy way is to put a switch on your bot. Program it in so that it tells what alliance you are on at startup. Example. You have a single position switch on the side of the bot. The people putting the bot in the crater set the switch for the blue alliance (switch closes the circuit on a digital I/O) the initialization code reads the state of that I/O and stores it in a variable called bool alliance (1 for blue, 0 for red). I hope this helps.
