Abstract
The present invention provides a dynamic searching device for toys, having at least two optical sensors to sense a target and a control circuit to compare the sensed signals of the two sensors and control a driver to move the toy, thus giving the toy dynamic movement.
Claims8
A dynamic searching toy comprising:
- a) a toy base having a plurality of wheels to movably support the toy base on a surface;
- b) a rotary stage rotatably mounted on the toy base so as to rotate with respect to the toy base;
- c) a plurality of spaced apart sensors on the rotary stage;
- d) a first motor for rotating the rotary stage relative to the toy base;
- e) a second motor for driving the wheels so as to move the toy base on the surface;
- and,
- f) a control circuit connected to the plurality of sensors, the first motor and the second motor, the control circuit including a comparator for comparing signals from the sensors such that, when the comparator receives signals from the sensors that are different from each other, the first and second motors are both actuated so as to move the toy base while the rotary stage rotates and, when the comparator receives signals from the sensors that are the same, both the first and second motors are deactivated so as to stop movement of the toy base and to stop rotation of the rotary stage.
