This study focuses on the innovative design and high mobility of intelligent security robot chassis, proposing a design scheme based on independent drive of servo wheel sets. The McNaught wheel omnidirectional motion system is adopted, enabling independent drive of steering wheels and drive wheels to achieve high-speed movement and agile turning in complex environments. The STM32F4 chip is used as the controller, integrating CAN bus communication and power, drive, and sensor modules. Structurally, the wheel system is optimized with expansion sleeves to enhance concentricity, and carbon fiber plates are used for lightweight design to improve stability. The gimbal mounting bracket undergoes finite element analysis to ensure structural integrity under extreme conditions. Functionally, the system integrates multiple sensors and camera devices, utilizing SLAM technology to achieve panoramic perception, autonomous obstacle avoidance, and mapping. Experiments show that the chassis has a minimum safety factor of 15 and a maximum displacement of 0.001932 mm, meeting application requirements. It provides technical support for security patrols in complex environments such as commercial plazas, demonstrating high application and promotional value. Intelligent security robots are equipped with functions such as high-speed movement, agile direction change, flexible turning and in-place rotation, which can meet the needs of various complex working environments.
