The manufacturer frames Microduck around action and locomotion, and Reachy Mini around human–robot interaction. Start with the kind of project you want to build.
Choose a question before a robot
“How can a robot keep its balance?” and “How should a robot respond during a conversation?” are both interesting questions, but they need different experiments. The first puts physical motion at the center. The second emphasizes communication and interaction. Buying based on a shared brand or a cute appearance can obscure that difference.
When Microduck is the closer fit
Choose the Microduck path when you want to investigate walking, contact, recovery or the transfer of a learned behavior from simulation. Your notebook might track initial posture, surface, commands and success across repeated runs. A useful first project is deliberately narrow: compare one behavior under two conditions and document what changed.
When Reachy Mini deserves a closer look
The launch article describes Reachy Mini as a platform for expressive interaction and conversational AI. If your project begins with a user saying something and the robot responding through voice or expression, study that platform’s current documentation. Do not infer that Microduck provides an identical interaction stack just because the same organization is involved.
A comparison that stays useful
Rather than making a universal winner table, compare your own requirements: physical movement, interaction model, supported development workflow, space, total cost and delivery timing. Read each product’s current documentation independently. We do not reproduce a Reachy Mini price here because variants and purchase terms need their own current check. A clear project goal will eliminate more uncertainty than a long list of loosely comparable specifications.
