while building the agentic mode in SimArena, I kept thinking about the UX problem most GenAI platforms have: you fire off a prompt and wait minutes for the entire scene to load before you can interact with anything I worked with @itsdamnvinci this week to make SimArena's workflow smoother. Instead of blocking operations, jobs run concurrently. scene objects stream in as lightweight placeholder boxes, then swap to final @NVIDIARobotics SimReady assets now you can keep working while your scene renders. no more waiting

We release Wuji MJLab, an open-source MuJoCo environment for dexterous hand manipulation. It includes a cube reorientation task, a sim2real pipeline, and the setup needed to reproduce the system. We will be at ICRA booth 121 with a live demo and welcome discussions on dexterous manipulation. Code: github.com/wuji-technology/w… Contributors: Jielin Wu, @yaoshzh, @BergerHunger, Li Chengmeng. This project is based on @kevin_zakka’s mjlab project.

We are back again :) After three weeks of quiet building. Introducing Genesis World 1.0, our latest simulation platform, the second release in our full-stack suite. Open-sourced. Robotics is still bottlenecked by the 1× speed of the physical world. Every model, checkpoint, and data recipe eventually needs to be tested on physical hardware, slowly, expensively, and with limited coverage. One hour in reality can become 100 days in simulation. That is how robotics model iteration moves from a wall-clock bottleneck to a compute problem. To make this work, simulation has to be both fast and trustworthy. Over the past year, we rebuilt the entire stack: a GPU-accelerated cross-platform compiler, penetration-free multi-physics contact solvers, unified rigid and deformable physics, and a photo-realistic renderer purpose-built for physical AI applications. We built Nyx, a high-performance path-traced rendering engine for robotics application. Genesis World 1.0 achieves near realtime performance with our latest development for penetration-free IPC solver, supporting various types of deformables beyond rigid bodies. It supports contact-rich, dexterous manipulation simulation across different embodiments: unitree, sharpa, wuji, genesis hand and various types of grippers. Under the hood is Quadrants, our effort in pushing forward cross-platform GPU-accelerated computation. Quadrants started as a fork of Taichi, and we rebuilt most of the critical parts for optimizing simulation workloads, giving 10x faster launch time and up to 4.6x runtime performance compared to the initial Genesis release. Together, they bring us to an unprecedentedly low sim-to-real gap, enabling zero-shot real-to-sim model evaluation and much faster iteration of GENE. All available today.
