The environment for developing RumiCar. Learn from the basics with sample programs and the simulator.

⚙

The library (such as the RumiCar GitHub) is where the programs and materials needed to run RumiCar are hosted.

⚑

Events and community gatherings, where you can build RumiCar vehicles, drive them, and learn how to program them.

We aim to provide an environment where anyone in the world can create autonomous driving programs. We will bring RumiCar not only to Japan but also to the rest of the world. Our goal is to make it possible for anyone to write autonomous driving programs for cars on public roads. In the future, we intend to turn RumiCar into a company.

RumiCar 35The core platform, including sample programs and exercises. MIT licensed, with documentation in both English and Japanese.RumiCar-Simulator 0A browser-based simulator reproducing the same sensor setup as the real car. Works with C/Python/JS, with zero external dependencies.RumiCar-PhotoStrip 0A bandwidth-friendly photo strip for any website, born on this very homepage. Zero dependencies, MIT licensed - commercial use welcome.RumiCar-VideoLoop 0Its sibling, also born here: a video digest window playing silent teasers in random rotation - click through to the full video. Zero dependencies, MIT.RumiCar-AutoPost-Guide 0Not code but a how-to: publish one WordPress post and the front page and Facebook Page update automatically. Bilingual, with the pitfalls and log-based checks we learned in operation.🎉 Now in the Arduino IDERumiCar-lib can now be installed directly from the Arduino IDE Library Manager.
