PLZ Fix error

You are attempting to construct your Talon and Joystick objects too many times. Try constructing them just once in robotInit().


Joystick mXboxController; // this will drive the robot
Joystick controlStick; // this will be for function of the robot such as toggle the conveyor belt and etc.

Talon frontLeft;
Talon frontRight;
Talon rearRight;
Talon rearLeft;

public void robotInit() {	// this code will be ran each time we power on the robot

  // Construct joysticks here
  mXboxController = new Joystick(0); // depends on the usb connected to computer
  controlStick = new Joystick(1);

  // Construct Talons here
  frontLeft = new Talon(3);
  frontRight = new Talon(2);
  rearLeft = new Talon(0);
  rearRight = new Talon(1);
}

Hope that helps.

Not a java guy, but I can’t imagine creating three instances of your joysticks and talons is a good thing. Try deleting the duplicate initialization in robotInit() and teleopInit() while waiting on someone better equipped to answer you.

<edit>Someone better equipped than I beat me to it. Good luck!</edit>

Thank you
