High-precision closed-loop motion chassis system for intelligent logistics trolley

This paper is a high-precision closed-loop motion chassis based on Arduino and programmed with C language. According to the application requirements, the chassis can realize omni-directional rotation movement in the field and accurate fixed­point parking and other work. By using advanced sensing technology and control algorithm, the motion accuracy and efficiency of the car can be improved. In this paper, the mechanical design scheme, hardware circuit design scheme and how to realize high-precision closed-loop movement of car chassis are described in detail, which provides reference for preparing logistics car competition and learning automatic control.
