Abstract
This document discloses twenty technical solutions for hydraulic drives, structural frameworks, and diagnostic systems of legged robots, unified by the design principle of a single physical element performing two or more functions simultaneously. These solutions encompass: self-diagnostic valves and seals utilizing impedance, piezoelectric, and NiTi mechanisms; damping and energy-recuperating structures based on magnetorheological fluids and liquid crystal elastomers; parametric metamaterial cells combining elastic, valving, and resonant functions; architectural designs for hardware-level hydraulic network survivability operating independently of electronics; cartridge interfaces with integrated opto-acoustic and electrochemical diagnostics; and a comprehensive structural joint architecture featuring three-level passive clamping and hydraulic lines routed internally through the load-bearing elements of a tensegrity framework.
