/***
 * This command will move the robot forward while lifting the defense arm up.
 *
 * pre-condition: robot is flush against the ramp of the outerworks in front of
 * the portcullis
 *
 * This command has to drive forward at the same time because that's how the
 * robot opens the portcullis
 *
 * post-condition: the robot has passed the portcullis and is in the next zone
