Abstract
The present invention is a control apparatus for guiding toy vehicles on a roadway. Preferably, a remote control hand unit is employed that is most preferably optoelectric. The hand unit includes a plurality of direction keys that transmit signals from the hand unit based on their electronic interconnection with an infrared LED and a laser transmitter in the hand unit. The hand unit transmits directional commands to control movement of a toy vehicle through the intersection of a roadway. These control commands are transmitted via a modulated infrared signal that is received by an infrared sensor adjacent the roadway. Additionally, the hand unit transmits a location laser signal to one of many reception points, i.e., laser detectors, located adjacent each road at an intersection.
