ABSTRACT:
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention relates to a dynamic searching device for toys.
(b) Description of the Prior Art
Many toys are often driven by mechanical devices to control the motion thereof, such as toy vehicles. However, the toys are generally controlled by remote control, and lack spontaneous and automatic movement and interactive operation. Compared to the fast development of interactive games, such as computer games, the conventional mechanical toys are relatively dull and cannot attract children.
SUMMARY OF THE INVENTION
The present invention is intended to provide a dynamic searching device for toys, which comprises at least two optical sensors to sense a target and a control circuit to compare the sensed signal of the two sensors and control a driver to move the toys with the sensor, thus giving the toys dynamic movement.
It is another object of the present invention to give the toys dynamic simulation effects by adding more movement or visual effect to the toys when the sensor is sensing the right target.
It is another object of the present invention to provide a dynamic searching device which can use sensors other than optical sensors.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing, in which:
