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.

Research Interests

My ultimate research goal is to build intelligent robotic agents that can operate robustly, adaptively, and autonomously in complex, real-world environments.

• RL with Priors: Reinforcement learning becomes sample-inefficient when the agent's degrees of freedom are high. How can we learn effective priors that reduce exploration space, enabling agents to master complex physical tasks?
• Sim-to-Real Transfer: Simulations provide scalable and safe environments for policy learning, but the reality gap persists. How can we bridge the sim-to-real gap so that policies trained in simulation seamlessly transfer to physical hardware?
• Humanoids & Vision-based Control: Humanoid morphology combined with egocentric vision provides versatile capabilities. How can we scale vision-guided control policies so humanoids can perceive and act autonomously in unstructured environments?
• Vision-Language-Action (VLA) Models: Integrating multimodal foundation models with lower-level robotic control allows agents to understand human intent and visual scenes. How can we leverage VLA models to achieve generalizable spatial reasoning and real-world task execution?

Publications

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.
