Open-source mobile robots
Wheeled robots: small differential-drive bases, holonomic bases and mobile manipulators, rovers and RC-car racers.
The atlas lists 17 open-source mobile robots. 11 publish a URDF or MJCF model for simulation. 13 publish a build cost; the US-dollar figures run from $50 for OpenBot (DIY vehicle body; smartphone not included) to $5.4k for TidyBot++ (mobile base for the Kinova reference design, arm not included). 11 carry a hardware license that permits commercial use, and 2 are licensed for non-commercial use only. The most-starred source repository here is JPL Open Source Rover's, with 9.7k GitHub stars.
Compare the mobile robots
Sorted by reproducibility score. A cost is the figure the source publishes, in its own currency, with its basis and what it covers.

Mobile robots in 3D
Renders come from each project's own source files; a card says so when there is no model yet.
