Bare minimum driving XRP Robot (blank template for Robot.java):

package frc.robot;

import edu.wpi.first.wpilibj.TimedRobot;

/** The methods in this class are called automatically corresponding to each mode, as described in the TimedRobot documentation. */
public class Robot extends TimedRobot {

  /** This function is run when the robot is first started up and should be used for any initialization code. */
  public Robot() {}

  /** This function is called once when teleop is enabled. */
  @Override
  public void teleopInit() {}

  /** This function is called periodically during operator control. */
  @Override
  public void teleopPeriodic() {}

  /** This function is called once when the robot is disabled. */
  @Override
  public void disabledInit() {}

  /** This function is called periodically when disabled. */
  @Override
  public void disabledPeriodic() {}

}

To get into a good spot to use the template, the following is the recommended approach:

1. Create a new XRP Timed Template project
2. Delete the default XRPDrivetrain class
3. Open the Robot.java file, delete all contents, and paste the above code in place of it

This approach is needed because the XRP libraries are not a part of the regular VendorDeps that you can install in a normal blank FRC project. This is one of the shortest paths to a blank project with the correct libraries for XRPMotor, XRPServo, etc to be available within the project.

From there we can walk through the build-out of a simple single-file robot program (no autonomous, etc.)

See the next section (if unlocked) for the completed example.
