About

Yubai Liu is a robotics researcher whose work centers on the design, control, and safety of two-wheeled inverted pendulum (TWIP) robots. His major contributions lie in addressing the fundamental instability of these compact, zero-turning-radius platforms, particularly in challenging real-world conditions. Liu pioneered methods for enabling TWIP robots to climb and descend slopes while maintaining an upright posture, a critical advancement for operator safety. He further enhanced robot stability through friction compensation techniques and the implementation of Mamdani fuzzy control systems for multi-degree-of-freedom platforms. His most cited work, "A two-wheeled inverted pendulum robot with friction compensation" (2015), has garnered 65 citations, underscoring its influence in the field. Liu has also explored terrain adaptability with a novel wheel-track robot capable of switching locomotion modes, and contributed to robotic safety through fault detection strategies using improved PCA for robots with self-adjusting center-of-gravity mechanisms. His research bridges the gap between theoretical control and practical deployment, making TWIP robots safer and more versatile for applications in personal transport and mobile robotics.
