Costs are the maker’s documented figures, with their original scope. Stars are recorded GitHub snapshots, never a quality score. Active: activity within 90 days of the snapshot. Quiet: within a year. Dormant: longer. Read between the files
02 READ BETWEEN THE FILES
A public repository is a start. A buildable robot takes more. We look at six parts of every project, so you know what’s there before you get your hands busy.
Design files and printable parts. See what you can make, modify, and put together.
A bill of materials. The shopping list behind the build, with costs where documented.
Circuit designs, boards, and wiring. Custom hardware or off-the-shelf components.
The software that brings it to life. Check the stack before you start building.
A digital model to test, train, and explore before the hardware meets the real world.
Assembly instructions. Because a folder full of files isn’t the same as a finished robot.
Those are different questions. Hardware and software can carry different licenses. Every listing explains what’s available and what the documented licenses allow. If we don’t know, we say so.
