About

Liu Lei is a robotics researcher whose work centers on autonomous navigation, nonholonomic control, and multi-agent systems, with a particular emphasis on wheeled mobile robots and competitive robotics platforms. His most influential contribution is the 2005 paper "Discrete Trajectory Tracking Control of Wheeled Mobile Robots" (5 citations), which introduced a novel discrete controller for nonholonomic vehicles. By integrating kinematic-model-based velocity control laws with backstepping technology, Lei's approach enables robust tracking of both continuous and discrete trajectories—a critical advancement for real-world robotic deployment where digital controllers must handle sampled data. This work provides a foundational framework for practitioners designing control systems for differential-drive robots. In parallel, Lei contributed to the RoboCup domain with "Key Techniques in RoboCup Middle-Sized Soccer Research" (3 citations), detailing the development of a SmartROB2-based middle-sized robot team. This paper addresses practical challenges in vision-based identification, localization, path planning, and decision-making, offering a systems-level perspective on autonomous soccer robots. Lei's research bridges theoretical control design with applied multi-robot coordination, making his work valuable for students and engineers working on mobile robot autonomy, embedded control, and competitive robotics.
