About
Dejia Che is a rising researcher in space robotics, specializing in the critical challenge of on-orbit servicing and debris removal. His work focuses on the safe capture and manipulation of non-cooperative, tumbling space targets—a key enabler for future missions to extend satellite life or clean up orbital debris. Che’s major contributions include pioneering a novel detumbling method that uses repeated tentative contacts from a robotic arm to gradually eliminate a target’s rotational motion, a process that relies on precise motion estimation. He has also advanced filtering techniques to handle the complex, unmodeled dynamics of “unfirm capture,” where relative motion persists between the target and robot end-effector after initial contact. His most-cited papers, with 7 and 5 citations respectively, have laid foundational work for robust estimation of target inertia properties and relative motion under highly uncertain conditions. By addressing these intricate coupling problems, Che is helping to make autonomous robotic capture of uncontrolled space objects a practical reality.
