Lightweight and Integrated Design of Tubeless Hydraulic Quadruped Robot Based on Additive Manufacturing

ABSTRACT Hydraulic quadruped robots exhibit exceptional terrain adaptability, offering significant potential for environmental exploration and military transportation. However, conventional hydraulic architectures are often plagued by excessive weight, complex pipeline network and mechanical interference, which restrict the improvement of its compactness and flexibility. To address these issues, this paper proposes a tubeless limb leg unit (LLU) featuring an electro-hydraulic hybrid drive and topologically optimized structural components. By exploring the relationship between moti
