UAVCAN is a lightweight protocol designed for reliable communication in aerospace and robotic applications via CAN bus.

Zubax Robotics employs UAVCAN as a primary communication interface for its products.

Key Features

  • Democratic network - no single point of failure.
  • Publish/subscribe or request/response exchange semantics.
  • Allows to efficiently exchange large data structures.
  • Lightweight, easy to implement protocol.
  • Supports network-wide time synchronization with microsecond precision.
  • Doubly-redundant or triply-redundant CAN bus.
  • Can be used in deeply embedded, resource constrained, hard real-time systems.
  • The specification and the reference implementation are open and free to use (MIT License).
