Department of Robot and Smart System Engineering, Kyungpook National University
- Worked with Dr. Yuvaraj and Dr. Bubryur Kim on autonomous exploration and hazard mapping for robotic inspection in unknown environments.
- Developed CRAFT, combining C*-based coverage planning with CUSUM gas anomaly detection. Suspected gas hotspots trigger finer local sweeps to improve concentration mapping and source localization.
- Integrated visual hazard detection with depth measurements and robot pose, locating hazards on the map and updating navigation costs so the rover can avoid them.
- Evaluated gas-triggered refinement in four GADEN simulation environments. Comparisons in three environments showed approximately 10–59% lower mean localization error than coverage without adaptive refinement.
- Deployed the integrated ROS 2 system on an NVIDIA Jetson Orin Nano rover, running navigation, gas monitoring, and visual hazard mapping onboard, with visual processing at approximately 15 FPS during the indoor deployment.
