Abstract
A light responsive remote control vehicle is operated in response to a beam of colored control light eminating from a hand operated and handheld controller. The vehicle is operative on a track having confining side walls and includes a pair of light sensors which respond solely to the illumination of the vehicle by the colored light beam. Electronic circuitry controls the operation of the vehicle in response to the relative illuminations of internal photosensors. A diffuser and light filter configuration is interposed between the controlled light and the photosensors to provide color selectivity.
