Abstract
A vehicle having four LDRs (light dependent resistors) on the upper surface thereof has a first motor for driving the vehicle in a forward or reverse direction and a second motor for turning the vehicle in a rightward or leftward direction. Selective light illumination on LDRs causes the vehicle to be propelled in a forward or reverse direction or to turn in a right or left direction. A selected LDR pair may be illuminated simultaneously to cause the vehicle to move forwardly and rightwardly; to move forwardly and leftwardly; to move rearwardly and rightwardly; and to move rearwardly and leftwardly. The LDRs may all be sensitive to the same radiation frequency range or may be responsive only to radiation frequencies in mutually exclusive ranges. A manually operated radiation frequency generator is used to illuminate the LDRs and control the car direction movement. The generator may have a single band of frequency ranges or may have specific limited and mutually exclusive radiation frequency bands. Each vehicle may have all of its LDRs sensitive to a given frequency range which range is mutually exclusive from the ranges of other vehicles.
