To meet the navigation needs of intelligent mobile robots in simple environments, an intelligent mobile platform control system based on the STM32F103C8 microcontroller was designed. This system integrates ultrasonic sensors, four infrared sensors, and photoresistors, and uses a TB6612FNG driver chip to control four-wheel DC geared motors. Remote control via Bluetooth is achieved through a mobile phone, enabling functions such as autonomous obstacle avoidance, infrared tracking, light source tracking, and Bluetooth remote control. Test results show that the obstacle avoidance success rate reaches 90%, the tracking accuracy is controlled within 5 cm, the light tracking response delay is less than 0.5 s, and the Bluetooth control delay is less than 0.3 s. This system provides a low-cost verification platform for the development of environmental perception modules in automotive driver assistance systems.
