Design of intelligent car with self-tracing based on STC89C52 MCU

In view of the tracking requirements of the intelligent car in the driving process, the control circuit with the STC89C52 MCU as the core is designed. The modular design scheme is adopted, and the color code sensor, metal detection sensor, ultrasonic sensor and Hall sensor are used to form different detection circuits to detect the car's track, detect embedded metal chips, avoid obstacles, measure speed and other problems, The circuit is analyzed theoretically and tested practically. The results show that the intelligent car has good identification and detection capabilities, and has the characteristics of positioning accuracy, stable and reliable operation.
