+ * 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
