    The 2nd BEHAVIOR Challenge is here! As embodied AI models advance at a rapid pace, it's more important than ever to understand where the field stands on generalizable solutions. With high-quality teleoperation data and strong pre-trained baselines including π₀ and GR00T, we

    1/N Long horizon, complex tasks that truly matter in everyday life are not solved problems by today’s robotics, requiring planning, object detection, object manipulation, and failure recovery. That's why Stanford's BEHAVIOR Challenge is back for year 2! Last year, the winning

    The world is not just made of words, and spatial intelligence was never just about perceiving and generating worlds. It's about interacting with them. Today, SceniX is joining World Labs. 🌎🤖👇

    I would also like to highlight @EvansXuHan’s remarkable growth in leading StereoPlolicy. He was already trained in machine learning before joining us, but robotics problems are full-stack problems. In this project, he went through a full journey of simulation, robot hardware,

    Excited to introduce StereoPolicy, led by @EvansXuHan. 📷📷🤖StereoPolicy is an effective way to add geometric cues to modern robot policy models while keeping the strengths of pretrained 2D encoders. ⁉️Why stereo for robot manipulation? Monocular RGB often lacks the depth

    RLHF is key for AI alignment, but simple A > B feedback often leads to causal confusion and spurious learning. Our new paper uses natural language rationales behind preference to fix reward misidentification and capture user's true intent! 📄: arxiv.org/abs/2603.04861 🧵👇 (1/9)
