About

Wenfei Liu is a robotics researcher whose work spans mobile robot localization, quadruped locomotion control, and computer vision-based positioning systems. Over the course of a research career stretching from the mid-2000s to the present, Liu has made meaningful contributions to two distinct but complementary areas: vision-based self-localization for mobile robots and stability control for legged robotic systems. Liu's early work introduced novel self-localization algorithms enabling mobile robots to recover both position and orientation from a single onboard camera image of identified landmarks — an elegant solution that leverages perspective geometry and inter-landmark visual angles to minimize sensor requirements. This line of inquiry culminated in the 2019 "Single-Camera Trilateration" framework, extending the approach to full 3D pose estimation using classical pinhole camera principles. More recently, Liu shifted focus to quadruped robotics, publishing work in 2023 on trot gait stability control that combines Model Predictive Control (MPC) with Zero Moment Point (ZMP) methods to address real-world terrain challenges. This paper has already attracted 13 citations, reflecting growing interest in robust legged locomotion. Collectively, Liu's contributions offer practical, elegant solutions at the intersection of perception and motion control in robotics.
