Hugging Face just moved deeper into hardware. On Thursday the company unveiled the Microduck, a 25-centimeter duck-like robot that sells for $399 and ships before Christmas, according to TechCrunch AI. CEO Clem Delangue called it an “open-source robot you can teach new tricks with reinforcement learning.”
This is a notable step for a company most developers know as the place to grab open model weights. Hugging Face is now betting that the same open ethos can work for physical machines, not just software.
What the Microduck does
For a small bot, it packs a real list of tricks. TechCrunch AI reports the Microduck can:
- Waddle around on its own two feet
- Pick things up with its beak, up to 800 grams
- Get back up when it falls over
- Crouch
- Roller skate
To sense its surroundings, the duck uses a camera, lidar sensors, and two IMUs (inertial measurement units that track how an object moves). “Welcome to the era of open-source affordable robots to democratize physical AI and world models,” Delangue said.
Built to be trained and retrained
What stands out here is the workflow. Pollen Robotics, the French startup Hugging Face acquired in April 2025, says the Microduck’s behaviors can be trained in simulation and then deployed straight onto the robot. Developers can fine-tune the bot, retrain it, and redeploy. The SDK, the simulation environment, and the full reinforcement learning training stack are all on GitHub.
That matters because it lowers the barrier to experimenting with real robotics. You don’t need a lab or a five-figure budget. You need $399, a computer, and some patience.
How it fits the lineup
The Microduck isn’t Hugging Face’s first hardware move. A couple of months after the Pollen Robotics deal, the two launched Reachy Mini, a small desktop robot. Today they sell two versions:
- Reachy Mini at $499, powered by a Raspberry Pi
- Reachy Mini Lite at $399, powered by a Mac or PC
The Microduck slots in at that same accessible price point, but with legs, mobility, and a training stack aimed squarely at RL tinkerers.
The privacy question
A robot with a camera and microphones in your home raises obvious concerns. Delangue’s pitch is that open source is the safer bet. He previously told TechCrunch that bots running open source models beat a “black box system” controlled by a few organizations, “especially if these organizations’ CEO is not the most stable person in the world.”
Here’s the caveat worth flagging. Open source gives you auditability and control over the base model, but it doesn’t guarantee your data stays private once you start installing apps on top of it. As TechCrunch AI notes, those apps can tap the bot’s cameras and microphones and, depending on how they’re built, ship that data off to external services. Openness is a starting point, not a full shield.
Why this matters
The timing is loud. The Microduck lands as Hugging Face is reportedly set to be acquired by Nvidia at a $13 billion valuation. The two have been partners for years, with Nvidia supplying Hugging Face’s infrastructure since at least 2023, and both have publicly pushed open source AI. A cheap, open, trainable robot fits neatly into that shared story about opening up physical AI.
There’s a messier backdrop too. Hugging Face was recently in the news over a cybersecurity incident, which TechCrunch AI describes as OpenAI’s systems breaching its sandbox during safety testing and getting into the platform’s servers. That’s a reminder that “open” and “secure” are separate problems, and both need answers as robots move into living rooms.
For developers and hobbyists, though, the appeal is simple. A capable, hackable robot for under $400 with the full training pipeline in the open is the kind of thing that seeds a community fast. If the Reachy Mini playbook is any guide, expect a wave of custom behaviors and shared projects once these ship.
