Micro-ROS is an embedded framework allowing you to connect low-power, cheap IoT devices into a ROS 2 system. By using Micro-ROS together with Husarnet peer-to-peer VPN your robot doesn't need to be in the same LAN as an IoT sensor.

Thanks to that your robot can be mobile/5G connected and talk directly with IoT sensors or actuators connected over Wi-Fi. Without any proxy server in between.

In this article I present a ready to use GitHub template for ESP32 Wi-Fi microcontroller allowing you to bring your ROS 2 powered IoT sensors to life in minutes.

ROS 2 is rapidly increasing its share in new projects in the AMR (Autonomous Mobile Robots) sector. While the amount of autonomous mobile robots is growing, the robotic fleet becomes less and less efficient. To overcome that, the next gen robots need to operate not as a group of individual devices, but as one, decentralized robotic system. That leads to connectivity challenges.

Classical approach with a standard DDS service discovery mechanism, relying on multicast messages being sent in a single LAN network, becomes a factor limiting a system's scalability.

Fortunately the eProsima Fast DDS Discovery Server combined with Husarnet peer-to-peer SDN solved all those issues by providing efficient way of service discovery and message exchange across devices connected to multiple physical networks.
