About
Hi, my name is Yeonwoo Choi. I am an undergraduate student in the Combined UG-G (Integrated B.S.-M.S.-Ph.D.) program at DGIST (Daegu Gyeongbuk Institute of Science and Technology), South Korea, and a member of the CSI Lab. I work on ROS 2, middleware, and networked robotic systems.
Research interests
- ROS 2 nodes, executors, and deployment on real hardware
- DDS / Zenoh and scalability when the number of participants or topics grows
- Wireless robotic networks - latency, loss, and discovery storms at scale
