A robot duck walking through simulated snow! 🦆 MicroDuck from @huggingface walking through a snowy scenery simulated in NVIDIA Newton with a custom snow solver. We all know that this robot duck is quite comfortable on the stage, but right now we can see it's quite capable in the snow too! ❄ The snow is done properly, and it's very important to go more in details here. Flake sizes, masses and fall speeds come from measured snowfall literature going back to the 1970s. Flakes tumble like thin plates. The rate is a real 8 mm/h liquid equivalent, around 290,000 flakes airborne at once. Snow sticks according to the angle of repose at air temperature, rides along in 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. Then checked against Isaac Lab running headless: observations matching to 1e-6, actions to 2e-6, an identical servo model across 4,088 random inputs, walking speed within 0.003 m/s. Twenty-two of twenty-two checks! ✅ Rendering snow is achievable!!! @TheRobotSimGuy 🐐, @NVIDIARobotics ~~ ♻️ Join the weekly robotics newsletter, and never miss any news → http://ziegler.substack.com Media
