Robot Intelligence Lab

Any sufficiently advanced technology is indistinguishable from magic.

Robot Intelligence Lab (RILAB)

RILAB focuses on the following research directions, among others:

- Motion retargeting for humanoid and quadruped robots
- Natural motion generation for legged systems
- Human-robot interaction for socially and physically interactive companion robots
- Embodied AI for robotics using multimodal foundation models
- Dexterous manipulation with robotic hands

Our lab is co-advised by Sungjoon Choi (Department of Artificial Intelligence) and Kyungjae Lee (Department of Statistics)

(notice) We are actively seeking undergraduate interns!

Sungjoon Choi (Dept. of AI)

My passion lies in the future of robots that coexist with human beings.

I am an Associate Professor at the Department of Artificial Intelligence at Korea University and a Principal Scientist at RLWRLD. Before joining Korea University, I was a Postdoctoral Researcher at Disney Research, Los Angeles, from 2018 to 2020, and a Research Scientist at Kakao Brain, Korea, in 2018. My research interests include, but are not limited to, the following areas: human-robot interaction (HRI), conditioned motion generation, and foundation models for robotics.

I previously received my Ph.D. degree in Electrical Computer Engineering at Seoul National University in Seoul, Korea, advised by Songhwai Oh. Before that, I received my Bachelor's degree in Electrical Engineering and Computer Sciences at Seoul National University. During my undergraduate years, I worked at Hanool Robotics in Bucheon, Korea, as a software engineer for three years.

Kyungjae Lee (Dept. of Statistics)

I am on a journey to explore the principles of intelligent decision-making.

I am currently an assistant professor in the Department of Statistics at Korea University, Seoul. Previously, I was an assistant professor in the Department of Artificial Intelligence at Chung-Ang University (2021–2024). I completed my B.S. in Electrical Engineering and Computer Science at Seoul National University in 2015 and earned my Ph.D. in Electrical and Computer Engineering from the same institution in 2021 under the supervision of Prof. Songhwai Oh.
