UAVCAN is an open lightweight protocol designed for reliable intravehicular communication in aerospace and robotic applications over CAN bus, Ethernet, and other robust transports. It is created to address the challenge of deterministic on-board data exchange between systems and components of next-generation intelligent vehicles: manned and unmanned aircraft, spacecraft, robots, and cars.
The name UAVCAN stands for Uncomplicated Application-level Vehicular Communication And Networking.
A quick introduction can be found in the UAVCAN crash course. A high-level overview is provided in the article "UAVCAN: a highly dependable publish-subscribe protocol for real-time intravehicular networking".
UAVCAN is a standard open to everyone, and it will always remain this way. No licensing or approval of any kind is necessary for its implementation, distribution, or use. Voluntary monetary donations are welcomed via Open Collective.
First, read the short UAVCAN crash course or the full UAVCAN specification. Familiarize yourself with the regulated DSDL repository. If you have questions or feedback, bring them to the discussion forum.
Pick one of the free open source implementations (MIT licensed) for use in your application:
None of the implementations suit your needs? Write your own! UAVCAN is a very simple protocol; an experienced developer can easily create a custom implementation from scratch to address the unique needs of their application.
The open source tools will help you design, develop, and maintain your UAVCAN-based application:
Please reference UAVCAN in scientific or technical publications.
