Sangwoo Han

I am an undergraduate student majoring in Artificial Intelligence Software at Cheongju University and an undergraduate researcher at VICA Lab (advised by Prof. Hyunguk Choi). Currently, I am working as a research intern at ROBIN Lab in DGIST, advised by Prof. Yongseok Lee, and will join the DGIST graduate program as an incoming graduate student.

Research Interests

My research goal is to advance Physical AI by combining real-world robot learning, realistic simulation, and robot foundation models to build agents that can interact robustly and autonomously with the real world.

  • Reinforcement Learning for Dexterous Manipulation: How can robots learn robust, adaptive skills for complex physical tasks through interaction with the real world and scalable reinforcement learning?
  • Real-to-Sim-to-Real Transfer: How can real-world interaction data help build accurate digital twins, so robot behaviors can be developed and refined in simulation before being transferred reliably to physical systems?
  • Humanoids & Vision-based Control: How can vision-based policies enable humanoid robots to perceive, manipulate objects, and act reliably in complex environments?
  • Robot Foundation Models: How can robot foundation models leverage diverse interaction data to perform long-horizon tasks and generalize across environments, objects, and real-world situations?

paper (DOI)

In this work, we propose a robotics-oriented evaluation protocol (ROEP) designed to systematically assess deployment-facing Vision-Language-Action (VLA) manipulation policies under real-world perturbations and operational conditions.
