Building the "App Store" for Robots: Hugging Face's Thomas Wolf on Physical AI
Hugging Face CSO Thomas Wolf argues robotics is at the same inflection point LLMs were a few years ago, and explains why affordable hardware plus open-source software is the unlock.
- Hugging Face acquired Pollen Robotics and launched its $100 robotic arm (SO-100) and $300 Ricky Mini consumer robot in mid-July 2025.
- LeRobot community has grown to 6,000–10,000 members across 100+ locations in 6 continents within roughly 18 months.
- Humanoids are hard to get below $10,000 because actuators alone are ~70% of the bill of materials; Wolf prefers a galaxy of cheaper form factors.
- Data diversity, not volume, is the core bottleneck in robotics — a robot trained in one room fails when wall color changes in the next room.
- World models (video generation fine-tuned to react to inputs) may be the first meaningful breakthrough in simulated training data for robots.
- Wolf visited China recently; Chinese AI teams open-source aggressively because they cannot sell APIs to Western markets anyway, giving them nothing to lose.
- LLMs are currently bad at asking the right scientific questions — they accelerate hypothesis testing but cannot yet identify what is worth studying.
- Wolf sees Anthropic as the last major Western lab yet to open-source a model and called it time to push them publicly.
