Robot Not Turning While in Autonomous Mode

[M15onebillion]

Hi, we are having problem with our Autonomous mode. Using the code below the robot seems to stop after going forward for 5 seconds, and does nothing afterwards.

public void autonomous() {
Chassidy.setSafetyEnabled(false);
Chassidy.drive(0.5, 0.0);
Timer.delay(5.0);
Chassidy.drive(0.0, 0.25);
Timer.delay(2.0);
Chassidy.drive(0.0, 0.0);
}


Does anyone know what is wrong with this code?
Much appreciated!
