About

Je Won Lee is a leading researcher in indoor mobile robot localization, with a particular focus on radio-frequency identification (RFID) tag floor-based systems. His work addresses the critical challenge of enabling robots to navigate precisely in indoor environments where GPS is unavailable. Lee’s most influential contribution, “Improving position estimation on RFID tag floor localization using RFID reader transmission power control” (2009, 31 citations), introduced a novel method to enhance accuracy by dynamically adjusting reader power, significantly reducing localization errors. He further advanced the field with “Mathematical formulation of RFID tag floor based localization and performance analysis for tag placement” (2010, 8 citations), providing a rigorous theoretical framework for optimizing tag layouts to maximize system reliability. Lee’s research is notable for its practical scalability, leveraging super-distributed RFID tag infrastructure (SDRI) to create cost-effective, easily expandable solutions for service robots. His work has been instrumental in bridging the gap between theoretical localization models and real-world deployment, influencing subsequent studies in sensor fusion and intelligent control. With a clear focus on solving fundamental navigation problems, Lee remains a key figure in the evolution of autonomous mobile robotics.
