Robotheca in numbers

Last updated: 21 October 2026.

How complete the library is today, measured with the rules the site uses everywhere. We publish these every week, good or not, because quality comes first.

The library

• 410 robots, 646 software projects and 72 AI models.
• 26 robots are Ready to build (see how we score), and 3 of them cost €200 or less.
• 53% of robots show a photo (218 of 410). A photo is shown only when its license allows it.
• 16% show a cost (66 of 410): the total of a complete parts list, or the figure the creator states.

Mission tests

Every week, four visitors with a goal use the site and say whether they would start a build: a beginner with a 3D printer and €200, a teacher who needs ten robots under €100 each, an AI builder who wants an arm, its software and a model that fit together, and an experienced maker who wants a humanoid or a robot dog. What stops them becomes the next week's work.

Latest (21 October 2026): 3 of 4 would start a build. Two of the three started only after checking the robot's repository themselves.
