About

Dr. Su Yong Kim is a leading figure in mobile robotics localization, specializing in the fusion of ultrasonic positioning and inertial navigation systems. His research focuses on overcoming the fundamental challenge of cumulative error in dead reckoning by integrating absolute positioning technologies. Dr. Kim’s most significant contribution is the development of the Pseudolite Ultrasonic System (PUS), a low-cost, high-precision method for estimating a mobile robot’s absolute position without error accumulation. His seminal 2011 work, "The localization of a mobile robot using a pseudolite ultrasonic system and a dead reckoning integrated system," which has garnered 23 citations, demonstrates a robust Kalman filter-based fusion of PUS with gyroscope data. This approach ensures high accuracy even in environments where GPS is unreliable. Earlier foundational work, including his 2010 study on the PUS and gyro integrated system (9 citations), established the core methodology. Dr. Kim’s research is notable for its practical, cost-effective solutions, as evidenced by his 2005 performance analysis of an ultrasonic positioning system using DGPS, which proved that ultrasonic systems can outperform more expensive absolute positioning alternatives. His work remains essential reading for engineers developing affordable, reliable navigation for autonomous ground vehicles.
