The Open Duck community

Huey stands on a lot of open work. Open Duck Mini by Antoine Pirrone and Microduck by Pollen Robotics started this family of small walking robots, and hundreds of people have built on them since: new bodies, trained networks, simulators, tools and videos. Here are 515 of their projects, each credited to the people who made it.

Huey is our own robot, made in Shenzhen. It is not a Pollen Robotics product and not endorsed by any project below. Every project belongs to its author and keeps its own licence; "none stated" means the author has not given a licence, so ask them before reusing it. Details as fetched on 2026-10-05.
