Mechanical engineering (B.S.) and about five years of Unity/C# software development.
I connect robot hardware, navigation and task execution, then check the results against real-robot runs and recorded logs.
🎓 Physical AI Semi-Humanoid Engineer Program, Dongguk AI Campus (July 6 to November 4, 2026, in progress)
🚗 AMR: ESP32 firmware, C++ base driver, Cartographer and Nav2. Verified a ~77 m corridor round trip and same-goal resumption after obstacle stops; reran 20 goals after a chassis change.
🥤 Dual-arm serving robot (team): ROS 2 Action workflows and Isaac Sim integration; a planning-based order completed nine stages in simulation. I worked on robot setup and integration; a teammate-trained SmolVLA policy completed one real-robot water-pouring and cup-placement sequence.
🐾 Isaac Lab / Go2: compared rewards and disturbances under fixed training budgets and repeated seeds, recording both trade-offs and experiments with no improvement. Results are from simulation.
🔧 Merged contributions: Navigation2 · MuJoCo Menagerie · small_gicp · Nav2 docs
🏆 NVIDIA Korea Agentic AI Hackathon 2026: Top 5 finalist with Team Mollet. Qualifying-round entry: RL Triage Agent, an Isaac Lab RL training triage agent built with Nemotron, NeMo Agent Toolkit and an OpenShell sandbox.
🧪 BreakTok: IMU device for detecting scrolling rhythms (TOYTHON 2026, top-20 final)
🕹️ Earlier work: mobile game development and operation; 80 WebGL science simulations; Python + Unity CLI parallel builds reduced build time by about 80%.
