With the rapid development of science and technology, modern society is gradually becoming more intelligent. The development prospects of intelligent cars and intelligent robots are getting broader. This design develops an intelligent line-following and obstacle-avoiding car based on the STM32f103C8T6 microcontroller. Taking the STM32 chip as the core control unit, it fully utilizes its advantages such as high performance, low power consumption, and rich peripheral interfaces to achieve various functions of the car. For the obstacle-avoiding function, by installing multiple types of distance detection sensors, such as ultrasonic sensors and infrared sensors, it can perceive the obstacle information in the surrounding environment of the car in real-time. The PID algorithm is used to process and analyze the data collected by the sensors, enabling the car to detect potential obstacles in the front, side, and other directions promptly during the driving process and make reasonable obstacle-avoiding decisions independently, such as changing the driving direction or pausing movement, to ensure the safe and stable operation of the car. This design combines embedded system development, sensor technology, and wireless communication technology. Through practical tests, the car can effectively achieve wireless intelligent control and obstacle-avoiding functions, has certain practical value and application prospects, and can be widely applied in many fields, such as smart home, warehousing logistics inspection.
