1. A method of guiding a vehicle, comprising the steps of: sensing a position of a laser beam using a laser sensor, the laser beam being projected along a guidepath; receiving a signal from the laser sensor, the signal being representative of the position of the laser beam; interpreting the signal; generating a control signal in response to the laser beam 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.
