I pulled a random street from Google Maps. Turned it into a 3D world with World Labs. Dropped a Unitree G1 into it and hooked it up to our server-side MuJoCo setup.

Now the G1 is actually walking around a real Malaysian street in my browser. Three.js is doing the rendering. MuJoCo is running the physics and walking policy on the server. A simple WebSocket keeps everything locked together.

Real street → 3D world → server physics + policy → live control in the browser. Kinda feels like cheating. Physical AI is getting wild.

Huge shoutout to @theworldlabs . Marble makes this stuff way too fun.
