In order to reduce costs, the circuit board of the entire vehicle is divided into two parts, the front and rear, using the same board. One board has two drives, which are installed on the chassis; the board integrates speed measurement, obstacle avoidance and tracking functions. The main control uses STM8, and the STM8 is used for communication. ESP8266 uses infrared transmitting and receiving tubes for obstacle avoidance and tracking. Attachment 12 is a demonstration video, and the compressed smartcar file is the program and chassis CAD file. The program now has forward, backward, turning and obstacle avoidance functions, and can be controlled using mobile phone WiFi. Other functions are still being improved.
