BUILD. CONTROL. UNDERSTAND.

Your robotics lab.
One browser tab.

Robot simulation that runs in your browser. Build a scene, drive it from Python, and see what your robots are doing.

MuJoCo runs locally on your machine. No remote physics server, and no simulator installation.

An actual Sim2Bot robotics scene with viewport editing and control tools in the dark interface. — Scene editing, robot control and telemetry in one place.

ONE CONNECTED WORKFLOW

01 Build a scene

02 Control from Python

03 Inspect the result

01 / BUILD

A scene that fits
your experiment.

Bring your own robot, or start with a model from the catalog. Add objects, cameras, lights and sensors; lay out a room; save and reload.

A scene tree and familiar editing tools keep the setup within reach.

Start with a robot Catalog examples

Or import your own MuJoCo robot package.

from sim2bot import Robot

# Connect through your local bridge.
with Robot() as robot:
    info = robot.describe()[0]
    robot.move_to(info.home)

    state = robot.state()
    print(state.q, state.tcp)

Run the local bridge and connect the simulator before running this example.

02 / CONTROL

Your code.
Your development tools.

Drive the robots from Python over a local bridge. Use WebSocket, TCP or UDP, with per-robot addressing for multi-robot scenes.

A starting point for sim-to-real

Prototype your controller in simulation before adapting it to a physical robot. A sim-to-real (sim2real) workflow still needs a compatible hardware adapter, calibration and real-world safety validation. Sim2Bot is the simulated endpoint, not a safety-certified robot controller.

Plan a sim-to-real workflow

03 / OBSERVE

See more than
a moving robot.

Inspect joint position, velocity, torque and TCP pose. Add cameras and sensors to see the experiment from another angle.

Telemetry reflects the rates your browser can sustain. Simulation timestep is not a guarantee of real-time performance.
