Hi there, I'm Joo-young 👋

🤖 About Me

Robotics software engineer (junior) — ROS 2 · C++ · Python · Linux

● Mechanical engineering (B.S.) + five years of Unity/C# software (mobile games, 80+ WebGL science sims).
● Robotics is where the two meet — so now I write software that runs on real robots.

🎓 Physical AI Semi-Humanoid Engineer Program, Dongguk AI Campus (2026.06 – 11) · B.S. Mech. Eng., Tech Univ. of Korea
🚗 JD-AMR Cube — real AMR bring-up: firmware watchdog, C++ ROS 2 base driver, SLAM & Nav2 integration
🦾 SO-101 arm — bus-servo bring-up → IK on hardware → depth-camera pick-and-place
🧪 BreakTok — IMU puck that notices doomscrolling from hand rhythm (TOYTHON 2026, top-20 final)
🌱 Write-ups of everything I build and read: hello, robot
🕹️ Before: Hardboiled Express (Google Play Featured, ★4.7) · Dannect (80+ WebGL science simulations)

🛠️ Tech Stack

ROS 2 C++ Python Ubuntu Gazebo C# Unity Claude Codex Git Notion SolidWorks

🧭 Now & Next
📍 Seoul · Physical AI bootcamp (Dongguk AI Campus) until 2026.11, then a junior robotics software role
🔧 Hands-on: Ubuntu 24.04 + ROS 2 Jazzy, Gazebo Harmonic, SLAM Toolbox / Nav2, Feetech bus servos, SO-101, JD-AMR
🧪 Latest build: BreakTok (TOYTHON 2026, top-20 final) → write-up · demo · repo
📚 Start here: gazebo-so101-capstone · robot-dashboard · bimanual-robot · deepthinkcar
