01 Profile
I study how to collect high-quality, physical interaction-aware data and use it to help robots learn human movements more effectively.
I have built a force-feedback leader-arm teleoperation system
designed specifically to collect high-quality demonstration data,
alongside a separate VR-tracker teleoperation system.
I evaluate multiple policies and refine their internal architectures
to improve learning performance, while extending vision–proprioception
policy architectures with force as an additional modality for
learning-based control of dexterous dual-arm robots with hands.
I also developed a ROS 2 visual-servoing package
during an internship with the Robot Control Team at Doosan Robotics.
02 Projects
Featured · Teleoperation
Developed a leader–follower system with gravity compensation and operator force feedback for contact-rich manipulation, designed to improve the quality of demonstrations for force-aware imitation learning. The same leader-arm interface also supports teleoperation of robot models in NVIDIA Isaac Sim.
Robot Learning
Evaluated and customized multiple policy architectures, collected teleoperation demonstrations, and deployed policies across single-arm, dual-arm, and dual-arm-with-hands setups. Current work extends vision–proprioception inputs with force.
Robot Control
Developed a Python-based ROS 2 visual-servoing package, built an SDF/Gazebo simulation, and ran the system in simulation and on physical hardware.
Built a VR-tracker teleoperation system for demonstration collection with transformation-matrix-based safety limits and a SLAM-enabled variant.
Integrated Robotics
Designed a manipulator-and-AMR workflow that verifies patient information, prepares prescribed medication, and delivers it autonomously.
Autonomous Systems
Built a custom AMR and compared four navigation configurations combining GMapping and Hector SLAM with TEB and DWA local planners.
03 Experience
Jul — Oct
Seongnam, Korea
Developed a visual-servoing example package for Doosan robot systems.
