Introduction

Welcome to AOS's main code repository. It contains two things:

AOS ("Autonomous Operating System") is an open source event-loop based framework for realtime robotic systems. You can learn more about it here.
A collection of software useful for robots, particularly the kind used in the First Robotics Competition.

Pleaes note: AOS moved here fairly recently and we are still cleaning up a few things, especially documentation.

Contributing

All development of AOS is done on our gerrit instance at https://realtimeroboticsgroup.org/gerrit with github being a read-only mirror. We are happy to add external contributors. If you are interested, reach out to Austin Schuh and he will help you get access. In case of disputes over if a patch should be taken or not, Austin has final say.
