Play with a physics-driven robot duck entirely in your browser

Robotics

What is microduck-simulator?

The Microduck RL playground runs a simulated robot duck with real reinforcement-learning policies directly in the browser, using MuJoCo compiled to WebAssembly. You can toggle between legged walking and wheeled skating, steer with the arrow keys, make it sit, roll, kick a ball and more, all without a server.

Who it is for

Developers and robotics hobbyists can experiment with on-device RL control loops and showcase physics-based demos without any installation.
