An axis of rotation of the gyroscope is parallel to the axis of rotation of the rotating structure. The controller is configured to generate a control signal to control the rotating structure and cause the rotating structure to rotate with respect to the undercarriage based on the command signal from the user interface and the data signal from the first gyroscope.
