Parts robots share

Read from the robots' bills of materials: how many robots list each part.

How the atlas is built

  1. Read the source. Each robot starts from its public repository, pinned to a commit, and the README, bill of materials and build guides it publishes.
  2. Render and extract. The 3D model is rendered from the project's own files; parts, costs and licenses are copied with a link to where each one is stated.
  3. Score and link out. A published rubric scores how complete the build documentation is. Code stays on GitHub, models and datasets on Hugging Face.

More on how the data is gathered and checked and how the score works.
