Panoramica, BOM e risorse
Overview
Open Duck Mini is built by Antoine Pirrone and the community, sponsored by Hugging Face and Pollen Robotics. Walking policies are trained in MuJoCo Playground and run on a Raspberry Pi Zero 2W.
Five joints per leg, four in the neck and head, and two antennas. The community has added shell, e-stop panel and head mods, and there is a Chinese build guide.
