Abstract

This design is a 2.4G wireless remote-control car based on STM32, including motor drive module, steering gear module, ultrasonic obstacle avoidance module, OLED screen display module, key input module, camera acquisition module and 2.4G wireless transmission module. L298N motor drive module to realize the forward and backward movement of the trolley; SG90 steering gear can realize the steering function of trolley; HC-SR04 ultrasonic measuring distance achieves obstacle avoidance function. The wireless remote-control module has two remote control modes: NRF24L01 wireless transmission and ESP32WIFI. In this design, the rear wheel is powered by two motors, and each module and the main control unit STM32 single chip microcomputer complete the corresponding functions, which can control the car to move forward, backward, turn and stop, respectively, through the mobile phone APP or remote control. The two remote control methods in this design provide an extra guarantee for solving the problem that the robot is out of control, and the control is safer.
