Design and stability analysis of a solar‐powered versatile patrol robot

In order to effectively solve the problem of energy autonomy of patrol robots in open‐air working environment and free them from the limitation of power lines on their activity range. In this article, a solar‐powered patrol robot based on a robot operating system is designed. The system adopts a modular design, using a master–slave distributed controller to control the robot's motion, and building an intelligent sensing system for the robot with various sensors. Meanwhile, flexible thin‐film solar cells and lithium batteries form a folded multi‐mode power supply system, which solves the problem of timely power supply. In addition, a simple and practical human–computer interaction interface is designed to facilitate viewing the robot's status. Finally, in order to verify the performance of the robot, the stability of the designed solar‐powered patrol robot is verified through different experiments, which has a reference value and practical significance for the development of patrol robots. The development of a patrol robot that uses thin‐film solar cells is an innovative approach that improves the practicality of the robot for outdoor use. The robot also features a variety of inspection functions and improves the performance and stability of the solar‐powered patrol robot from multiple perspectives.
