Robot simulation that runs in your browser.
Sim2Bot runs MuJoCo locally in the tab — nothing to install, and no cloud machine stepping your physics. Build a scene, then drive the robots from your own Python over a local bridge.
Runs on your machine
The simulation is MuJoCo compiled to WebAssembly, stepping in your browser on your GPU. Hosting serves the page; it never runs your physics.
Control it from Python
A local bridge speaks WebSocket, TCP or UDP, with multi-robot addressing. The same code that drives a simulated arm can drive a real one.
Works offline
No account required. Scenes save locally in the browser, and cloud sync is additive — turn it off and everything still works.
Bring your own robot
A catalog of arms, mobile bases and drones, plus MJCF and mesh upload for models you already have.
Real telemetry
Joint position, velocity, acceleration and torque, TCP pose, cameras and sensors — streamed at rates the browser can honestly sustain.
Scenes you can build
Add objects, cameras, lights and sensors; lay out rooms; save, reload and share. A CAD-style tree with keyboard shortcuts.
