About

Yousheng Yang is a robotics researcher whose work sits at the intersection of hydraulic actuation, legged locomotion, and biomechanically inspired mechanical design. Best known for his contributions to the development of HyQ — a hydraulically actuated quadruped robot designed for highly dynamic tasks such as running and jumping — Yang has helped establish hydraulic drive systems as a compelling alternative to electric actuation in autonomous legged platforms. His most-cited work, a 2008 paper on the HyQ hopping leg prototype (78 citations), laid the conceptual and engineering foundations for a robot capable of navigating complex outdoor environments with agility and robustness. Yang's research has consistently addressed critical practical challenges in this field, including energy-efficient fluid power systems, precise leg control and modelling, and the comparative performance of water versus oil hydraulics. His 2009 investigation into energy-efficient hydraulic drives reflects a forward-thinking concern for sustainability in autonomous robotics. Additional contributions include novel electro-hydraulic valve design and systematic analysis of leg mechanisms optimized for dynamic performance. Collectively, his body of work — accumulating over 160 citations — has meaningfully advanced the engineering science underpinning next-generation mobile robotics capable of real-world deployment.
