ESP32 Small Robot Dog (SovGVD)

A small hobby quadruped robot dog with three degrees of freedom per leg (12 DoF total), inspired by the Petoi Bittle. The structural parts are distributed as FreeCAD source files only, and the ESP32 control firmware lives in a separate repository (SovGVD/esp32-robot-dog-code). The author has explicitly closed the project: some dependencies have aged out, not every planned feature shipped, and no PCB was ever produced. It remains a useful reference design but is not actively buildable without significant rework.

What you get

• A standardized, machine-readable robot schema derived from the source repo.
• A limited/simplified source 3D asset is available from body/small_dog.FCStd.
• Source-backed bill-of-materials evidence is linked with per-part provenance where available. Prices marked estimated are not yet verified against a vendor.
• A transparent reproducibility score so buildability is a sortable, first-class property.
• Cross-links to the source repo, datasets, models, and forks.
