Abstract: Starting from the kinematic model of a mobile robot, this paper analyzes the implementation principles of its various motion states and develops a hardware platform for the system using a DSP chip as the main controller of the motion control system. To ensure that the robot's motion meets the requirements of high control accuracy, speed, and stability, a fuzzy PID algorithm is used as the system's control algorithm, and a specific implementation method for the algorithm is proposed. Finally, the system's software design architecture is introduced. Keywords: Motion control; Fuzzy PID; DSP 0 Introduction Research on mobile robots began in the late 1960s. With the development of computer technology, sensor technology, and information processing technology, mobile robots have been widely used in industries such as manufacturing, agriculture, medicine, and security patrol. Faced with unstructured working environments, mobile robots perceive the environment through their own sensors, acquire the necessary environmental information, and, combined with their own motion, plan the next motion requirements through specific control algorithms, which are then implemented by driving the motion mechanism. It is through continuous environmental perception, dynamic decision-making, and motion control that mobile robots can smoothly avoid various obstacles and move quickly and accurately from the initial point to the target point. Environmental perception and dynamic decision-making constitute the upper-level subsystem of the mobile robot control system, providing control decisions for the lower-level motion control. The lower-level motion control subsystem is the foundation for the robot to successfully complete its tasks, and motion control is also one of the important factors affecting robot performance. This paper mainly focuses on the motion control system of a mobile robot. To achieve high precision, no overshoot, and fast and stable control, a fuzzy PID control algorithm is used as the motion control algorithm for this robot. Simultaneously, to meet the real-time requirements of the system and to keep the system as simple as possible, a TMS320LF240A DSP chip is used as the microcontroller for the mobile robot's motion control system. The hardware platform composition and software design architecture of the system are introduced. For details, please click: Research on the Motion Control System of a Wheeled Mobile Robot Based on DSP
