About

Liwei Ni is a robotics researcher whose work centers on the design and control of advanced wheel-legged robots for operation in unstructured, off-road environments. His primary contributions lie in the development of novel suspension systems that integrate active and passive elements to simultaneously achieve precise posture control and superior ride comfort. Ni’s most influential paper, “Parameters uncertainty analysis of posture control of a four-wheel-legged robot with series slow active suspension system” (2022, 36 citations), addresses the critical challenge of maintaining stability despite system uncertainties. His earlier foundational works, including “Posture Control of a Four-Wheel-Legged Robot With a Suspension System” (2020, 21 citations) and “Design and Posture Control of a Wheel-Legged Robot With Actively Passively Transformable Suspension System” (2020, 19 citations), introduced the concept of an actively-passively transformable suspension—a key innovation that allows each leg to adapt to terrain irregularities while isolating vibrations. Collectively, his research has garnered over 79 citations, establishing him as a notable figure in mobile robotics. Ni’s work is particularly relevant for students and engineers interested in mechatronics, robust control, and the practical deployment of all-terrain robots.
