Research Focus – Core Components of Humanoid Robots

Engaged in long-term research on the design theory, experimental study, and engineering application development of core components for humanoid robots. Applied research focuses on areas such as multi-degree-of-freedom dexterous hands, electrically driven robotic joints, planetary roller screw mechanisms, and miniature ball screw mechanisms. The work systematically addresses key engineering challenges including reliability during long-term service, degradation of accuracy retention, and fatigue life prediction of core components, aiming to provide a solid foundation of parts for independently developing high-performance humanoid robots in China.
