Arduino open-sources RouterBridge_ROS: real-time MCU I/O talks directly to ROS 2
kscottz · x · 2026-11-10
At ROSCon Global 2026 in Toronto, Arduino's R&D team unveiled ArduinoRouterBridgeROS, an open-source library that lets real-time microcontroller I/O on dual-brain boards like the VENTUNO Q publish and subscribe directly to ROS 2 topics on the Linux MPU.
- Built on MsgPackRPC: the Linux side (Python) and the MCU side (a Zephyr-based Arduino sketch) expose functions via Bridge.provide() and invoke them via Bridge.call(), eliminating custom serial protocols and heavy middleware wrappers.
- A technical blog post, GitHub repo, and documentation are available to get started with ROS 2 on the UNO Q.
