1. A method of guiding a vehicle, comprising the steps of:

  • determining a sequence of directions in which to sequentially point a laser beam to delineate a curvilinear guidepath;

    sequentially projecting the laser beam in the sequence of directions to delineate the curvilinear guidepath;

    sensing a position where the laser beam strikes a laser sensor;

    receiving a signal from the laser sensor, the signal being representative of the position where the laser beam strikes the laser sensor;

    interpreting the signal;

    generating a control signal in response to the position where the laser beam strikes the laser sensor being greater than a predetermined distance from a predetermined reference position relative to the laser sensor, the control signal being configured to control the vehicle to track the position of the laser beam; and

    sending the control signal to a drive actuator.
