Abstract: This paper proposes an intelligent road maintenance robot system, focusing on its mechanical structure design and performance optimization. The system adopts a modular design concept, achieving structural streamlining through a lightweight aluminum alloy frame and a carbon fiber shell. Innovatively, a differential transmission system and a three-axis articulated robotic arm structure are designed, utilizing a symmetrical bevel planetary gear set to achieve torque distribution, and reducing weight through topological optimization of the thin-walled structure and aluminum alloy casing. Comprehensive finite element analyses were conducted on critical components of the system, including static structural mechanics, transient dynamics, and fluid dynamics simulations. Experimental results show that the system demonstrates excellent mechanical performance, with collaborative operation efficiency reaching 2.3 times that of traditional separate equipment, and total energy consumption reduced by 40%, providing a reliable solution for intelligent urban road maintenance.
