Hugging Face robot duck walks in simulated snow with 290,000 physics-simulated flakes

Hugging Face's MicroDuck robot duck walks through a snowy scene simulated in NVIDIA Newton with a custom snow solver — and the physics is surprisingly rigorous: flake sizes, masses and fall speeds come from snowfall measurement literature dating back to the 1970s, flakes tumble like thin plates, and the 8 mm/h liquid-equivalent snowfall keeps 290,000 flakes airborne at once.

Snow sticks according to the angle of repose at air temperature, rides along each link's own frame as the robot moves, and the feet press footprints into a 2 mm-resolution snowpack. The walking policy was trained in Isaac Lab and reimplemented in pure Newton without the Isaac Lab runtime.
