Hugging Face can’t make its viral $400 robotic duck fast enough.
The Brooklyn-based company, often described as the GitHub of open-source AI models, launched Microduck in four colorways shortly after news broke that Nvidia was buying the firm for $12.9 billion. The robot, developed in collaboration with Hugging Face’s subsidiary Pollen Robotics, instantly became a surprise hit.
Hugging Face reported more than 10,000 Microduck preorders in the first week, which amounts to over $4 million in revenue. The launch was unusually strong by consumer robot standards.
It doubled the number of units that Sony sold in 1999 when the Japanese tech giant launched its first AIBO robotic dog. However, Aibo was pricier starting over $2,000, so it generated more revenue. A fairer comparison is JIBO, which was also marketed as a relatively affordable companion when it launched via crowdfunding in 2014. JIBO reached about $1 million in the first 6 days, about a fourth of what Microduck generated.
Whether robot ducks have lasting power is an open question. While AIBO, Jibo, and others proved that demand for consumer robots exists, they’ve also shown that launch day excitement and long-term viability are two very different things.
The Microduck idea goes back at least two years. It began as a side project called Open Duck Mini by Antoine Pirrone, an engineer at Pollen Robotics, the French startup Hugging Face would later acquire. The Bordeaux team had developed Reachy, a cartoon-like, research-grade humanoid robot that rolled on wheels instead of walking. Its second generation version sold for about $70,000 to places like Cornell University and Carnegie Melon University.
As Pollen became known as one of the few companies outside China actually shipping humanoid hardware, Pirrone was trying to make a small build-it-yourself version of Disney’s walking BDX droids. The small bipedal Star Wars characters had begun wandering around Galaxy’s Edge in late 2023, first at Disneyland in California and later at Disney’s Hollywood Studios in Florida.
They resembled baby versions of BD1 from the video game Jedi: Fallen Order. Walt Disney Imagineering and Disney Research developed the robots to move and behave more like animated characters than theme park robots. They stand 66 cm (2 feet 2 inches) and weigh around 15.4 kg (34 lbs). Fourteen powered joints control their legs, head, and neck.
The team reportedly used commercially available motors from the Chinese company Unitree Robotics and South Korea’s ROBOTIS. Their onboard artificial intelligence is powered by Nvidia Jetson hardware.
Disney animators created the behaviors for the robots to learn with reinforcement learning. In a physics simulation, thousands of the robots’ digital twins practiced staying balanced while copying the animators movements. The AI mainly handles balance, walking, and physical control, while Disney keeps human control over their personalities and actions.
The Open Duck Mini project published to GitHub in early 2025. Its repository links to a public Google Sheets bill of materials (BOM) listing the parts needed to build it with a targeted total cost under $400. It also links to the full OnShape CAD model for the mechanical design. The Open Duck Mini uses 14 serial bus servos by the Chinese company Feetech that are relatively inexpensive compared to the motors used by Disney.
Hugging Face announced its acquisition of Pollen Robotics for an undisclosed price in April 2025. The deal was meant to combine Hugging Face’s open-source LeRobot software with Pollen’s hardware to make capable robots more affordable and accessible.
Within a few months, they launched Reachy Mini, a small desktop robot marketed as a relatively low-cost entry into physical AI. Standing 28 cm (11 inches) and weighing 1.2 kg (3.3 lbs), the Reachy Mini is designed for expressiveness rather than mobility.
It uses a 6-degree-of-freedom head, full-body rotation, and two animated antennas to communicate through movement. The robot comes equipped with a wide-angle camera, four microphones, and a 5-watt speaker so it can see, hear, and respond to users. The entry model is priced at $399 while a wireless version goes for $449.
Within a year of its debut, Reachy Mini had reached about 10,000 units in the wild. Pollen’s new duck-like companion hit that number in less than a week.
Microduck is clearly part of the same design lineage as the Open Duck Mini, but it looks much less like Disney’s droids. Pollen Robotics redesigned it to look more like an original character with a rounded body, shorter proportions, a movable beak, and a friendlier toylike aesthetic.
Priced at $399 before taxes, it’s marketed as an affordable platform for learning physical AI. It stands 25 cm (9.8 inches), weighs under 800 grams (1.8 lbs), and has 15 degrees of freedom (DoF) in its legs, head, and neck. Its beak can pick up small objects and optional wheels makes it move faster.
The Microduck perceives its surroundings with a front camera and a small LiDAR depth sensor. Two motion sensors help it stay balanced and react to its surroundings. A Chinese Rockchip RK3566 processor powers its onboard AI with 8 TOPS of compute. The system supports 1 GB of memory and 32 GB of storage. According to its developers, the Microduck can do basic moves out the box, while users can teach it new tricks in simulation.
Pollen and Hugging Face initially said orders would ship before Christmas. They’re now warning customers that the overwhelming demand means there’s a 4 to 6 month wait.
They’re working with the Chinese company Seeed Studio to ramp up production. The Shenzhen-based firm is also the official manufacturing partner for the Reachy Mini.
The mechanical design appears to use Dynamixel XL series smart servos that are priced around $27 a piece. Even with factory pricing, Hugging Face and Pollen are likely selling the Microduck at near cost. The memory alone is reportedly more than 10 percent of the robot’s cost. Instead of turning a profit, they’re trying to get thousands of open-source robots into Hugging Face’s ecosystem to upsell them later.
People who don’t want to wait half a year for a Microduck may have another option if they’re willing to build it themselves.
Andrea Espazito, a former Tesla Optimus engineer who’s now developing a dexterous hand for Foundation Future Industries, says he reverse-engineered the duck’s design. He set up a website with a signup form and a message saying he might open source the bill of materials, CAD files, and assembly instructions if there’s enough interest. He calls the project Macroduck.
Though Microduck is made largely from Chinese components, the FCC’s new restrictions of foreign-made robots do not apply because it falls below the weight threshold of 2 kilos or 4.4 lb.
