    Excited to share MolmoAct 2, a fully open robotics foundation model for real world deployment! This model can handle bimanual tasks like making coffee, bussing tables, and assisting with lab workflows. It’s fully open, with our model weights, code, 700+ hours of real-world

    Robotics models often struggle outside controlled environments. Ours is built to work in real ones. Today we're launching MolmoAct 2, which can assist with a host of chores & lab tasks, plus the MolmoAct 2-Bimanual YAM dataset—the largest open robotics dataset of its kind. 🧵

    Unveiling Tether: autonomously scaling robot data using a novel few-shot imitation learning method! Our robot performs autonomous functional play with the environment for 26+ hours and produces 1000+ expert level trajectories—1 every 86 seconds—which improves downstream policy

    Introducing Tether 🪢, a fun little idea to scale data by having our robot “play” in the real world for over 24 hours, throughout the day and overnight—improving policies from zero to mastery with minimal supervision! But play is messy, with out-of-distribution scenarios that
