About
Ulrich Walter is a leading authority in space robotics, with his research fundamentally advancing the autonomous operation of free-floating and dual-arm space manipulators. His work is critical for the future of on-orbit servicing (OOS), addressing the unique challenges of repairing and refueling satellites in the harsh environment of Earth orbit. Walter’s major contributions include pioneering the use of Particle Swarm Optimization (PSO) for trajectory planning, as demonstrated in his most-cited paper (150 citations), and developing non-linear model predictive controllers for obstacle avoidance (109 citations). He has also made significant strides in coordinated control for dual-arm systems (103 citations) and in the complex task of detumbling and capturing non-cooperative, tumbling targets—a key challenge for active debris removal. His foundational 2009 paper on “On-orbit servicing” (76 citations) remains a seminal reference, while his work on telepresence for OOS (37 citations) explores the feasibility of human-in-the-loop control from the ground. With over 600 total citations, Walter’s research is not only highly cited but also directly applicable to future space missions, ensuring safer and more efficient operations beyond Earth.
