این روزا توی بحث رباتیک خیلیا سر و دست می‌شکونن واسه ابزارهایی مثل آسترا تا دنیای واقعی رو ببرن توی شبیه‌ساز، اما شارون لی اومده وسط و می‌گه شبیه‌سازی فقط قیافه و ظاهر نیست، بلکه فیزیک درست‌درمون و فهم دقیق کارکرد اجسام می‌خواد

Been seeing a lot of Astra for real2sim, but what you need for robotics: physics and affordance. Our SOTA recipe specifically solves for: • Affordance: model object details that convey functionality. • Physics: calibrate simulation dynamics against real-world observations. Our agent has the action space of a “full-stack simulation engineer” and jointly considers geometry, materials, colliders, articulation, and physics. It automatically calibrates physics against real trajectories and matches task-specific dynamics. Simulation environments is useful only if it can provide meaningful policy level signals. Methods, comparisons, and results below.
