About

Young Jae Lee is a pioneering researcher in the intersection of mobile robotics and bio-inspired underwater vehicle design. His work primarily focuses on advancing navigation systems through vision-based Simultaneous Localization and Mapping (SLAM) and distributed filtering techniques, as well as exploring the hydrodynamics of ostraciiform swimming for robotic propulsion. Lee’s most influential contribution, “Improving mobile robot navigation performance using vision based SLAM and distributed filters” (2008, 17 citations), addresses the critical challenge of accurate positioning in GPS-denied environments like tunnels and underground facilities, integrating encoder data with visual SLAM to enhance navigation robustness. He further extended this work by fusing vision-based SLAM with nonlinear filters, providing a practical, integrated navigation solution for simple planar robots. In parallel, Lee made notable strides in biomimetics, experimentally characterizing ostraciiform swimming with rigid caudal fins (2009, 4 citations) and identifying fish-like robot dynamics using inertial sensors (2006, 2 citations). These studies laid groundwork for alternative underwater propulsion methods, demonstrating how turning and thrust can be controlled through fin motion. Lee’s dual focus on robust robot navigation and bio-inspired locomotion highlights his commitment to solving real-world autonomy challenges, making his research valuable for students and engineers developing robots for complex, unstructured environments.
