About

Yongqiang Xu is a pioneering researcher in space robotics, with a focus on the control and planning of walking robots designed for extravehicular operations on space stations. His most cited work, "On control and planning of a space station robot walker" (2002, 17 citations), introduces a novel five-degree-of-freedom robot with two lightweight, flexible links arranged in an inverted V-shape. This robot can autonomously step from one node of a space station trusswork to the next, addressing critical challenges in mobility and stability within microgravity environments. Xu’s contributions lie in developing advanced control algorithms and motion planning strategies that enable precise, adaptive locomotion on complex truss structures, enhancing the feasibility of robotic assistants for maintenance and assembly tasks in space. His work has influenced subsequent research in flexible-link robotics and space-based automation, laying groundwork for future autonomous systems on orbital platforms. Though his citation count is modest, Xu’s research represents a foundational step in the evolution of space-walking robots, demonstrating practical solutions for in-orbit robotic mobility.
