About

Lifeng Shi’s research focuses on humanoid robotics, with a particular emphasis on motion planning and state classification for bipedal machines. His major contribution lies in decoupling the complex motion-planning problem into two tractable sub-problems: topological state planning and detailed motion planning. By proposing a systematic classification of basic robot states—including lying, sitting, and standing—Shi provided a foundational framework that enables humanoid robots to transition smoothly between postures and recover from falls. His most-cited work, “Classification of Lying States for the Humanoid Robot SJTU-HR1” (2009, 12 citations), exemplifies this approach by specifically addressing the challenge of lying-state recognition, a critical capability for autonomous fall recovery and safe operation. Though his citation counts are modest, Shi’s ideas have influenced subsequent research in humanoid locomotion and state-based control, particularly for robots operating in unstructured environments. His work on the SJTU-HR1 platform represents an early, systematic effort to bridge the gap between high-level task planning and low-level motion execution, offering a clear, modular methodology that continues to inform the design of more adaptive and resilient humanoid systems.
