About

Yijun Chen is a researcher specializing in space robotics, autonomous systems, and spacecraft dynamics and control. Their work focuses on the complex challenges of robotic manipulation in space environments, where the absence of gravity and the presence of dynamic coupling between mechanical systems create unique engineering difficulties. Chen's most influential contribution, "Dynamics and control of capture of a floating rigid body by a spacecraft robotic arm" (2014), has garnered 43 citations and addresses one of the most technically demanding problems in on-orbit servicing — the controlled capture of uncooperative or free-floating objects, a capability critical for satellite servicing and debris removal missions. Their follow-up work examining the role of joint friction in space robot dynamics (2015, 38 citations) further refined modeling approaches for robotic systems operating in space, where accurate dynamic models are essential for precise control. Together, these contributions reflect Chen's dedication to bridging theoretical dynamics with practical control strategies for next-generation space robotic systems. Their research holds significant relevance for advancing autonomous in-orbit assembly, satellite repair, and active debris removal technologies.
