I am a Master's student in Artificial Intelligence at Sogang University, advised by Prof. Changjoo Nam. My research interests include multi-robot systems, path planning, and autonomous exploration. I did my Bachelor's degree in Software Convergence (Robot Vision track) at Kyung Hee University.

Research

I'm interested in multi-robot systems, autonomous exploration, and multi-agent path planning.

Submitted
Multi-Robot Exploration
Decentralized Multi-Agent Exploration without Communication under Budget Constraints
Janghyun Cho*, Jimmy Chiun*, Guillaume Sartoretti , Changjoo Nam
Submitted, 2026

A decentralized budget-aware exploration framework for communication-free teams with directional sensing. Rather than exchanging maps, goals, or messages, each robot coordinates through its incidental observations.

Multi-Agent Path Finding
Scalable Multi-Robot Path Planning in Continuous Space
Joonyeol Sim, Joonkyung Kim, Janghyun Cho, Changjoo Nam
Submitted, 2026

Two-level approach in which the low-level is a sampling-based single-robot path planner, Safe Interval RRT* (SI-RRT*), that finds a collision-free spatio-temporal trajectory for an individual robot.
