Abstract

This study investigates the synergistic optimization of modular structural design and assembly performance in robotic arms. By systematically elucidating the fundamental principles, classification framework, and interface standardization methodologies of modular design, we establish a comprehensive methodology spanning structural design to assembly integration. The research analyzes optimization strategies for critical processes including precision control, sequence planning, and quality stability during assembly, while proposing a corresponding integrated evaluation system. The study reveals the intrinsic influence mechanism between design parameters and assembly processes, establishing a structure-process collaborative design framework to achieve comprehensive balance among multiple objectives such as module independence, system integrity, lightweight design, and assembly efficiency. Results demonstrate that through lifecycle-wide collaborative optimization, modular robotic arms can significantly enhance reconfigurability, assembly efficiency, and maintenance convenience while maintaining functional and precision requirements. This provides theoretical basis and practical pathways for developing high-performance robotic arm systems tailored to flexible manufacturing demands.
