Intelligent tracking trolley

The utility model provides an intelligent tracking trolley which comprises a photoconductive resistor A, an LED (light emitting diode) A, a motor A, an LM393 comparator integrating module, a motor B, an LED B and a photoconductive resistor B which are connected by a power in sequence, wherein the LED A is connected with the photoconductive resistor A, the LED B is connected with the photoconductive resistor B, the photoconductive resistor A and the photoconductive resistor B are connected with the LM393 comparator integrating module, and the LM393 comparator integrating module is respectively connected with the motor A and the motor B. By using the LM393 comparator integrating module, light can be reflected onto the photoconductive resistors by the ground, resistance values of the photoconductive resistors can be compared by the LM393 comparator integrating module, and when the values are unbalanced (for example, one side presses a black track), a motor at one side can be controlled to stop, and a motor at the other side rotates in a way of accelerating, so that the direction of the trolley can be corrected so as to go in the correct direction again. The trolley can automatically run according to an established route without manual control, is high in tracking accuracy and can be promoted to carry out practical application.
