Reflected light controlled vehicle

Abstract

The remotely controlled toy vehicle of the present invention is configured to respond to a tracking signal of a narrow beam of non-visible light that is projected onto the surface of the ground in proximity of the toy vehicle. The sensors mounted on the toy vehicle are configured to receive, and respond to, the light energy of the beam that is reflected off the surface of the ground. The controller, which is the source of the tracking signal, is a handheld component configured to project the beam of non-visible light to a location as desired by the user. A beam of visible light is also projected as an indicator of the location of the tracking spot. Operation of the toy vehicle is controlled by moving the tracking spot. Preferably, the control circuitry is configured such that the toy vehicle follows the tracking spot. Alternatively, the remotely controlled toy vehicle of the present invention is configured to respond to an auditory tracking signal.
