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

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. 🧵

I still believe you need to know robotics to solve robotics. At the very least, that should be a prerequisite.

People making grand claims about #robotics really need to spend time with actual robots. Debug the controller yourself. Deal with contact, latency, calibration, failures. And before declaring old problems obsolete or rebranding long-standing robotics ideas around foundation

Really great discussion with @bgxc! Learned a lot about the deeper reasons behind @LightwheelAI’s focus on egocentric data collection, and how it all connects back to simulation. Highly recommend watching this episode!

Robotics has a data problem, and egocentric data is a compelling way to solve it because egocentric data is (1) scalable — it’s cheap to collect — and (2) easily captures the breadth and diversity of real human tasks, while (3) being true to real physics. Lightwheel recently

GPT-6 Astra is really cool. It can solve the task using an LLM harness and even turn the result into this awesome video. Sim env using this: github.com/allenai/molmoa…
