🧠 Can a single robot policy control many, even unseen, robot bodies? We scaled training to 1000+ embodiments and found: More training bodies → better generalization to unseen ones. We call it: Embodiment Scaling Laws. A new axis for scaling. 🔗 embodiment-scaling-laws.github.io 🧵👇

🤔 Have @OpenAI o3, Gemini 2.5, Claude 3.7 formed an internal world model to understand the physical world, or just align pixels with words? We introduce WM-ABench, the first systematic evaluation of VLMs as world models. Using a cognitively-inspired framework, we test 15 SOTA…

Time to democratize humanoid robots! Introducing ToddlerBot, a low-cost ($6K), open-source humanoid for robotics and AI research. Watch two ToddlerBots seamlessly chain their loco-manipulation skills to collaborate in tidying up after a toy session. toddlerbot.github.io

Learning bimanual, contact-rich robot manipulation policies that generalize over diverse objects has long been a challenge. Excited to share our work: Planning-Guided Diffusion Policy Learning for Generalizable Contact-Rich Bimanual Manipulation! glide-manip.github.io 🧵1/n
