I found the problem. Turns out it was a problem with the code.
Code:
myRobot = new RobotDrive(0, 1, 2, 3);
myRobot.setExpiration(0.1);
xbox = new Joystick(0);
xbox2 = new Joystick(1);
LF = new Victor(0);
LR = new Victor(1);
RF = new Victor(2);
RR = new Victor(3);
FARM = new Talon(4);
RARM = new Talon(5);
lintake = new Talon(6);
rintake = new Talon(7);
I didn't know that RobotDrive constructed/declared/identified (I don't know what the term is... oops) the motors, and then I constructed the motors later, so I constructed them twice and the builder didn't like that. Thanks for taking the time to respond though.
