Microduck buyers guide: is it worth $399, and who should buy it

Full disclosure first: this guide is written by the team that sells Microduck. That is exactly why it aims to be useful rather than flattering - it exists to help you decide, including deciding that a different robot fits you better. There is no countdown timer here; the pre-order is not going anywhere.

The short answer

• Buy Microduck if you want a real walking robot that also invites you to retrain it - playable in the first hour, open-sourced all the way down.
• Do not buy it if you want a sealed appliance with an app, a talking assistant, or a robot that does the thinking for you.
• Pick something else if your heart is in building (Open Duck Mini), interaction (Reachy Mini), quadrupeds (Petoi Bittle) or manipulation (SO-101). The alternatives tour is the honest map.

What $399 actually buys

One payment, before taxes and shipping - and this is the full list:

• The robot, assembled and calibrated, in one of four colourways: Cream, Graphite, Lavender or Sky.
• A rechargeable battery, a USB-C cable and a game controller - the drive-it-tonight kit.
• Seven trained moves, installed: standing up, sitting and standing, walking, turning, kicking, driving and grabbing - each one explained on the moves page.
• The open-source software stack: Python SDK, browser simulator, reinforcement-learning environments and the sim-to-real workflow, Apache-2.0 on GitHub.

Nothing else is required to use the robot. The three optional packs - Charger $39, Accessory $39, Dev $119 - are covered pack by pack on the accessories page.

What it asks of you

• A little desk space. Hard, flat surfaces are where the walking policies are strongest. Rugs are an experiment, not a home.
• Curiosity about the second act. The first evening is driving; Python, training and modding are where owners say the real value lives.
• A computer for programming - not for driving. The balance loop runs onboard at 50 Hz and the controller works with no laptop at all. The computer is for the first Python session and training your own moves.
• Patience with physics. It is a 25 cm biped; floors, rugs and desk edges all push back. If that sentence sounds like an invitation rather than a warning, this is your robot.

Who Microduck is for

• Reinforcement-learning learners - the full sim-to-real loop on affordable hardware, not a simulator-only exercise.
• Python developers - a desk-sized robot with a real SDK: clone the repo and read the code that moves it.
• Makers and modders - the shell opens, spares exist (the Dev pack), and the DIY guide draws the line between what is published and what is not.
• Teachers, clubs and labs - a visible balance problem, a zero-setup browser simulator and a five-session outline ready to adapt.
• Desk-robot owners who outgrew sealed pets - the same desk presence, but the ceiling is where you take it.

Who should pick something else

• You want interaction, eye contact and an app library - that is Reachy Mini, the same maker's companion robot at $399 Lite / $499 Wireless; read the head-to-head.
• You want the build itself to be the hobby - Open Duck Mini v2 is a project rather than a product; buy or build, compared.
• You want a robot dog for a classroom or a kid - a quadruped like Petoi Bittle is steadier on that brief: biped or quadruped.
• You want to race robots for free, with no hardware - that is Beni, a browser game in the same training ecosystem: two open projects, compared.
• You want to shop the whole category - the alternatives tour sorts nine robots by intent.

The honest caveats

• It is a pre-order. Ordering opened on 27 August 2026 and the first deliveries are targeted before Christmas 2026. The pre-order guide and the shipping timeline describe exactly how that works, step by step.
• The hardware is not open source. The software stack is Apache-2.0 - the retrainable part - but the mechanical and electronic design files are not published. The DIY guide is precise about the boundary.
• The policies are state of the art, not magic. Surface, lighting and wear all matter; a walking robot that never wobbled would be a render, not a robot.
• There is exactly one official store. Microduck is sold direct on this site, not on marketplaces - run the five-point check before paying anyone.
• It is not an assistant. No chat, no subscription, no cloud account required to make it walk. It is a robot duck with a job: locomotion you can retrain.

The total, spelled out

All prices before taxes and shipping, paid once, with no subscription anywhere in the list. If you buy one thing only, buy the robot: it is complete on its own.

The five-minute decision test

1. Watch a robot walk, or hold a robot that reacts to you? Walking, and the answer is Microduck; reacting, and it is Reachy Mini.
2. Do you want to build it, or drive it tonight? Tonight, and it is Microduck; build, and it is Open Duck Mini.
3. Will you open the SDK within a month? Yes means you are the target owner; no means you are buying the most interesting desk toy - which is allowed, but know which one you are doing.
4. Would a robot dog suit the household better? Then compare properly: Microduck vs Petoi Bittle.
5. Is the delivery date critical for you? If yes, read the shipping timeline and write to support before ordering.

Before you pay

Microduck is sold in exactly one place: microduck.homes, direct from the maker. No authorised resellers, no marketplace stores, no second brand shop - the official sources page is the checklist, where to buy explains ordering in detail, and the pre-order page is the checkout itself. Order, shipping or payment questions: support@microduck.homes.

Buyers guide FAQ

Is Microduck worth $399? It is the cheapest route we know to a retrainable walking biped with published training code and a real SDK. If what you want is a companion robot rather than locomotion, Reachy Mini costs the same and does that job better - the reviews page shows how to judge the claim for yourself.

Do I need any pack on day one? No. The robot is complete in the box. The Accessory pack is the most common first add-on because it unlocks roller mode - the pack comparison says which one fits which owner.

Is there a subscription or a cloud fee? No. One-time payment, and the software is open source; updates come from the project on GitHub.

Will it be obsolete next year? The hardware does not change with software fashion, and every move is retrainable - that is the opposite of obsolete by design. What the robot is next year depends mostly on what you train.

I have never trained an AI. Is that a problem? No. Drive first, simulate second, train third - the getting started guide and the training guide are the path, and the browser simulator lets you practise the whole loop before your duck arrives.
