Design and Realization of Intelligent Wheelchair Based on STM32

Abstract

In response to the market demand of people who need special care, a smart wheelchair based on STM32 is designed. Through the STM32F103ZET6 development board, it uses the smart car (simulated electric wheelchair) as the carrier with the attitude calculation algorithm, GPS positioning, Lora wireless communication, PWM speed control and distance detection, the gesture control of the movement and steering of the car, automatic obstacle avoidance, GPS Real-time transmission of positioning information, one-key call for help, and video recording of unexpected situations. The gesture recognition rate of the system is stable and the safety is high, and it can meet the requirements of wheelchair intelligence.
