About

Lige Zhang is a robotics researcher whose work centers on biomimetic locomotion, soft robotics, and bioinspired mechanical design. Best known for pioneering contributions to underwater robotics, Zhang has dedicated much of his career to developing robotic fish systems that replicate the elegant propulsion mechanisms found in nature. His most influential work, "Design of a robotic fish propelled by oscillating flexible pectoral foils" (2009), introduced a groundbreaking approach to biomimetic fish design, incorporating molding soft bodies and pneumatic artificial muscles to mimic pectoral fin movement — a paper that has garnered 36 citations and remains a foundational reference in the field. Building on this foundation, Zhang extended his research to model the remarkable hydrodynamic properties of cownose rays, producing kinematic analyses and optimized mechanical designs for bionic pectoral fins that prioritize efficiency, stability, and low noise. His 2013 studies further refined flapping foil mechanisms that faithfully replicate natural fish motion. Beyond aquatic robotics, Zhang has also explored unconventional locomotion systems, including tetrahedral rolling robots. Collectively, his body of work reflects a consistent commitment to translating biological principles into practical, high-performance robotic systems, making him a meaningful contributor to the growing field of bioinspired engineering.
