About

Guoyan Xu is a robotics researcher whose work focuses on the design, modeling, and control of mobile robots capable of navigating complex, unstructured terrains. A central theme in Xu’s research is enhancing robot mobility and stability through novel mechanical design and intelligent control. Xu’s most impactful contribution is the design and kinematic modeling of a passively-actively transformable mobile robot (56 citations), a system that combines passive and active mechanisms to traverse rough and uneven ground. Building on this, Xu analyzed the lateral stability of such robots using an active adjustable suspension (29 citations), addressing a critical challenge for climbing slopes and obstacles. Xu has also explored autonomous navigation, applying reinforcement learning for obstacle avoidance in self-driving vehicles (24 citations). More recently, Xu has investigated robots with variable-diameter wheels (3 citations), enabling attitude adjustment to improve terrainability in cluttered environments. Through these works, Xu has advanced the field of field robotics by developing practical, mechanically innovative solutions for locomotion on challenging terrain, with a combined citation count exceeding 110, demonstrating a growing influence in mobile robot design and control.
