About

Si Zhang’s research lies at the intersection of humanoid and quadruped robot locomotion, dynamic interaction, and biomechanically inspired control. His major contributions center on enhancing walking stability and slip prevention—critical challenges for robots operating in real-world environments. He pioneered yaw torque compensation for fast humanoid walking (21 citations), addressing the rotational instability that causes foot slip during high-speed gait. Zhang also developed trot pattern generation for quadruped robots using ZMP stability margin (19 citations), and introduced human-like pelvic rotation patterns to improve walking speed and naturalness (6 citations). His work on ground reaction force features (6 citations) bridges human biomechanics and robot control, enabling more efficient, compliant locomotion. Beyond walking, Zhang designed an anthropomorphic 7-DOF arm for dynamic ping-pong rally tasks (5 citations), demonstrating fast, interactive manipulation. His slip prevention strategies, including coordinated acceleration vector control (2 citations) and simultaneous rotational/translational slip prevention (4 citations), provide foundational solutions for bipedal stability on low-friction surfaces. With over 60 total citations, Zhang’s research offers practical frameworks for students and engineers aiming to build robots that walk, run, and interact as robustly as humans.
