About

Ji-Ho Lim is a researcher specializing in autonomous robotic systems, sensor fusion, and human-robot interaction. His most-cited work introduces a novel human-following robot system that leverages Ultra-Wideband (UWB) technology with a moving anchor configuration. In this system, the target person wears one UWB sensor as a moving anchor, while the robot is equipped with two UWB tags. By modeling triangulation based on inter-sensor distances, the robot can calculate both the angle and distance to the target without requiring fixed reference points—a significant advantage for dynamic environments. The system also incorporates obstacle avoidance to maintain safe, seamless tracking. Although his citation count is currently modest, this work represents a practical contribution to mobile robotics and indoor localization, with potential applications in service robots, assistive technology, and industrial automation. Lim’s research addresses key challenges in real-time person following and sensor-based navigation, laying groundwork for more adaptive and infrastructure-free robotic systems. His focus on moving anchor UWB positioning offers a scalable solution for human-robot collaboration in unstructured settings.
