UAVCAN

Zubax Robotics is the main developer and maintainer of UAVCAN – an open lightweight data bus standard designed for reliable intravehicular communication in aerospace and robotic applications via CAN bus, Ethernet, and other robust transports.

UAVCAN is an integral part of the Dronecode core infrastructure (the Dronecode project is maintained by The Linux Foundation) and is used by numerous vendors and companies all over the world.

Features

• Democratic network – no bus master, no single point of failure.
• Publish/subscribe and request/response (RPC) data exchange semantics.
• Efficient exchange of large data structures with automatic decomposition and reassembly.
• Lightweight, deterministic, easy to implement, and easy to validate.
• Suitable for deeply embedded, resource constrained, hard real-time systems.
• Supports dual and triply modular redundant transports.
• Supports high-precision network-wide time synchronization.
• The specification and high quality reference implementations in popular programming languages are free, open source, and available for commercial use (MIT license).
