Introducing FRAX: Fast Robot Kinematics and Dynamics in #JAX — to be presented at the 2026 IEEE International Conference on Robotics and Automation (ICRA) Frontiers of Optimization for Robotics (FOR) Workshop. FRAX delivers extremely fast (low-microsecond) execution for common inverse-kinematic and inverse-dynamic control workloads, with a pure Python codebase that can achieve up to 5× faster performance than MuJoCo or Pinocchio Python bindings in several settings. At the same time, FRAX is fully differentiable and seamlessly compatible with CPU, GPU, and TPU execution through #JAX — enabling scalable workflows spanning robotics, control, planning, and machine learning. Our broader goal is to help bridge the gap between modern AI tooling and robotics computation, making it easier to develop scalable #Physical #AI systems. This also makes FRAX a great complement to CBFPY (github.com/StanfordASL/cb…), our package for robot safety and control barrier functions. Kudos to @danielpmorton for leading this effort. If you’ll be at ICRA, reach out! The FOR Workshop is on Monday, June 1, and we’ll have a poster there. 💻 GitHub: github.com/StanfordASL/fr… 📄 Paper: arxiv.org/pdf/2604.04310 #Robotics #PhysicalAI #JAX #DifferentiablePhysics #MachineLearning #AutonomousSystems #GPU #Simulation #ICRA

Most capable generalist robotics models today are closed or at best, open weights. But robotics won’t reach its ChatGPT moment without real openness. That GPT moment was built on years of open tools and datasets such as Python, PyTorch, ImageNet and more, that let researchers inspect, reproduce, and build. Today, we’re introducing MolmoAct 2: a fully open-source action reasoning model for real-world robotics. We rethought and reshaped everything! 🧵👇






We've shipped more than a thousand versions of Zed, but all of them began with zero. Today, that changes. zed.dev/blog/zed-1-0









Scientists often make breakthroughs by synthesizing ideas across papers. In our new paper, we ask whether a language model can anticipate this process: given two parent papers, can it generate the core insight of a future paper built on them? 🧵⬇️


GEN-1 puts plushies into polybags, in a warehouse outside the lab in New Hampshire.

Releasing the Unfolding Robotics blog! Time to unfold robotics: we trained a robot to fold clothes using 8 bimanual setups, 100+ hours of demonstrations, and 5k+ GPU hours. Flashy robot demos are everywhere. But you rarely see the real story: the data, the failures, the engineering. We’re sharing everything: code, data, and details in the blog → huggingface.co/spaces/lerobot…
