Design of self-avoiding car for disaster relief based on STM32

With the frequent occurrence of extreme weather and various natural disasters caused by global warming, the casualty rate in the face of disasters cannot be underestimated. In today's information age, it needed to reduce the casualty rate in the face of disasters by combining traditional rescue knowledge and modern equipment, so this paper decided to develop disaster relief vehicles. The rescue vehicle is developed based on the STM32 chip, combining the basic requirements of the rescue vehicle and other functions of the chip, capable of autonomous operation of the motor module, with obstacle avoidance function, Bluetooth connection function, pulse-width modulation (PWM) signal input. Finally, after long hours of hard work, field testing and code debugging, all functions can be implemented normally. However, there are still some problems to be solved in the future, such as the operation of cars in extreme conditions, such as sand, dirt. Or the tolerance of the chip under high temperature conditions because high temperature may cause chip damage. The emergence of disaster relief vehicles may provide a new idea for the whole disaster relief team - unmanned rescue. It has also played a leading role in the development of unmanned rescue in the future.
