Real trained RL policies for the Microduck robot, running fully in the browser: MuJoCo compiled to WebAssembly steps the physics, onnxruntime-web runs the policy network at 50 Hz. No server, no backend. Two locomotion variants of the same robot are included: legs (walking, the default) and rollers (the wheeled skating variant). Press M (or hold D-pad up ~1 s on a gamepad) to switch; the roller model, meshes and policies are lazy-loaded on the first switch. | Mode | Checkpoint | What it does | |--------|-----------|--------------| | Run (legs) | BESTalphawalking.onnx | Velocity-tracking locomotion (arrows / WASD to steer) | | Sit | BESTalphasitstand.onnx | Sits down on its hull, stands back u...

Why It Has Market Pull
Officially published by a Hugging Face-owned robotics company, this browser sandbox runs the real trained walking and skating policies for a $399 open-source robot via physics-in-WebAssembly and an ONNX runtime in the browser, and has already spawned independent community forks.
- 510 Hugging Face likes, last updated just days before this evaluation
- Published under the official robotics-company org, the maker of a well-known open-source robotics platform
- Tied to a real $399 hardware preorder covered by Engadget, MarkTechPost, and Interesting Engineering
- Eight community discussion threads, including a full community fork that a team member praised directly
- Runs genuine reinforcement-learning policies client-side via an ONNX web runtime plus a physics-to-WebAssembly build — a real sim-to-real workflow, not a rebranded demo
