This invention discloses a modular design method and system for a fully automated inspection robot, relating to the field of automated inspection technology. The method includes: dividing the robot system into multiple functionally independent modules; acquiring the state parameters and operating parameters of each module; and generating module output data based on these parameters. During task execution, the robot optimizes its output at each task stage by dynamically adjusting the combination and weights of the modules. Module selection is based on a comprehensive evaluation of error minimization and inter-module synergy. The optimal module is selected according to real-time task and environmental changes, and the module configuration is adjusted in real-time. This invention addresses the problem that existing robot systems typically employ fixed structural designs, lacking flexibility and adjustability between modules, and unable to quickly switch and adjust between different tasks, thus affecting the overall efficiency and stability of the robot system.
