Microduck Review: Pollen Robotics’ Open-Source Biped Robot Under Hugging Face

What Is Microduck?

Microduck is a small biped robot from Pollen Robotics, the robotics team under Hugging Face. It is about 25 cm tall, looks like a compact duck-like robot, and is designed for more than simple remote-control play. Its real point is giving developers and robotics learners a small open-source platform for movement learning, reinforcement learning, and sim-to-real experiments.

According to Pollen Robotics, Microduck includes 15 motors, a camera, an 8×8 ToF LiDAR, two IMUs, microphones, a speaker, NFC, Wi-Fi, Bluetooth, and a beak-like gripper. The company shows it walking, crouching, sitting, grabbing small objects, recovering after falls, and moving in playful skating-like motions.

Why we built a small biped robot, how it complements Reachy Mini, and where we hope it can go.

The important framing is that Microduck is not just a finished toy. Its SDK, simulation environment, and reinforcement learning stack are published on GitHub, so developers can study how it works and build new behaviors.

Quick Summary

What is Microduck?

  • A compact open-source biped robot from Pollen Robotics under Hugging Face
  • About 25 cm tall and roughly 780-800 g
  • Equipped with 15 motors, a camera, 8×8 ToF LiDAR, two IMUs, microphones, a speaker, NFC, Wi-Fi, and Bluetooth
  • Ships with a gamepad for out-of-the-box control
  • Built around an SDK, simulation, reinforcement learning, and sim-to-real workflows
  • As of August 29, 2026, it is a pre-order product, with first deliveries targeted before Christmas 2026

What's good

  • A rare low-cost entry point for biped robotics and reinforcement learning
  • Strong open-source alignment through Hugging Face and Pollen Robotics
  • Gamepad control makes the robot approachable before writing code
  • Public GitHub resources make it easier to inspect before buying
  • Small enough for a desk, home lab, classroom, or robotics club setting

What to watch out for

  • It is still a pre-order product, so long-term user reviews are not available yet
  • Walking stability, durability, support quality, spare parts, and repairability still need real-world confirmation
  • Buyers in Japan should check shipping, tax, warranty, radio compliance, and support language
  • It looks friendly, but it is closer to a developer robot than a child-focused toy
  • Battery life is listed around one hour, so it is not a always-on companion robot

Who it may suit

  • Developers who want to learn reinforcement learning, robot control, and sim-to-real deployment
  • People following Hugging Face, LeRobot, and open robotics
  • Robotics learners who want a small physical biped robot rather than only a simulator
  • Makers who enjoy tuning behaviors and experimenting with real hardware
  • Users who value building and testing more than polished companion features

Bottom Line

Microduck is interesting because it makes physical AI feel more accessible. It packages biped walking, fall recovery, a gripping beak, gamepad control, sensors, and an open-source learning stack into a 25 cm robot.

The official pre-order price is listed as $399 before tax and shipping, which is about 63,600 yen using the August 27, 2026 reference estimate of roughly 159.4 yen per dollar. The Pollen Robotics store also shows €340.00 EUR, about 63,100 yen using roughly 185.6 yen per euro. Those numbers put Microduck far below most serious legged robots, while still giving developers real hardware to experiment with.

That said, Microduck should not be treated as a Japanese conversational pet robot, a family monitoring device, or a low-maintenance toy. Its core value is movement learning, robotics development, and open-source experimentation.

Price, Availability, and Buying Notes

Price

The Pollen Robotics store lists Microduck at €340.00 EUR. Using the European Central Bank reference rate from August 27, 2026, roughly 185.6 yen per euro, that is about 63,100 yen before any additional fees.

The official Microduck page and launch materials also describe the pre-order price as $399 before tax and shipping. Using the same date's derived estimate of roughly 159.4 yen per dollar, that is about 63,600 yen.

These yen figures are only rough references. The actual amount paid from Japan can change with card exchange rates, payment fees, shipping, import duties, and taxes.

Shipping timing

As of August 29, 2026, the official store says the first deliveries are targeted before Christmas 2026. That should be read as a target, not a guaranteed arrival date.

Pre-order hardware can slip because of manufacturing, certification, logistics, and customs. If someone wants Microduck specifically as a Christmas gift, it is safer to treat the timing as uncertain.

Sales regions

The store lists Japan among the initial regions, alongside the US, Canada, EU, UK, Norway, Switzerland, and South Korea. That is a positive sign for Japanese buyers.

Still, buyers in Japan should check radio compliance, warranty handling, return policy, replacement parts, and whether support is available in a language they can use comfortably.

What Microduck Can Do

Gamepad control

Microduck ships with a gamepad, so users can start by driving built-in behaviors before writing code.

That matters because biped robotics is easier to understand once you see the robot deal with balance, friction, floor surfaces, and falls in the real world.

A gripping beak

Microduck is not a humanoid with arms, but its beak acts like a small gripper. Pollen Robotics shows it grabbing and carrying lightweight objects.

This does not make it a home chore robot. It is better understood as a small physical AI platform where walking, approaching, gripping, and recovering can be studied at desk scale.

Fall recovery

Falls are part of biped robotics. Microduck is shown recovering from common fall positions, which is important for experimentation because real floors, battery levels, timing, and foot friction can all change the outcome.

Reinforcement learning and sim-to-real

This is the most important part of Microduck. The official materials describe a workflow with MuJoCo simulation, PPO reinforcement learning, ONNX export, and deployment to the real robot.

In plain terms, Microduck is meant to let people train a movement policy in simulation, then bring that behavior onto real hardware. That is a much deeper idea than simply choosing canned motions from an app.

Open-source learning

The official GitHub repository explains the software architecture, including daemons on a Rockchip RK3566 system and a 50 Hz control loop for 15 servos.

Even before buying, the repository gives developers a way to inspect how the robot is built and how much of the stack is likely to be accessible.

Buying Risks to Check First

It is still a pre-order product

Microduck was announced in August 2026. Official videos and press photos are useful, but broad user reviews, long-term durability reports, support experiences, and repair stories are not available yet.

Legged robots can look smooth in demo clips but behave differently on a home's actual floor. Early buyers should be comfortable with some first-batch uncertainty.

It is not mainly a children's toy

Microduck looks cute, but it has 15 moving motors and a removable battery. It should not be treated like a soft plush toy.

For use with children, check the target age, pinch points, charging safety, floor space, fall behavior, and whether an adult can supervise operation.

It is not a Japanese chat companion

Microduck includes microphones and a speaker, but its current positioning is movement learning and robot control. If the goal is Japanese conversation, daily voice prompts, or emotional companionship, a robot designed around speech and daily interaction will be a better fit.

Battery life is around one hour

The store lists about one hour of use with a removable NP-F550 battery. That is reasonable for a moving robot, but it is short if someone imagines an always-present pet robot.

Summary

Microduck is a strong product to cover because it represents a bigger shift: AI is moving from screens into small physical bodies that individuals can actually buy and program.

The best angle is not just "a cute duck robot." It is that Hugging Face and Pollen Robotics are trying to make open-source robotics, reinforcement learning, and sim-to-real experimentation accessible at a much lower price point than traditional research robots.

The caution is just as important. Microduck is still a pre-order product, and real-world quality, shipping reliability, warranty handling, Japan-specific compliance, and long-term support still need to be confirmed.
