I turned the @vibe_robotics A1 humanoid into an interactive 3D anatomy lesson. My DIY kit just arrived, so I asked Claude Opus 5.5 to explain how it works by building an interactive @threejs model from Vibe’s real CAD files, joint data and open-source SDK specs. Cut it open. Follow the power and data. Watch how it balances while walking. Look inside one of its 25 servos. I open-sourced the whole thing: https://21nemus.github.io/vibe-a1-explainer/
