On the way to achieve autonomous node communication Elixir
summary
Rclex embeds ROS 2’s RTPS/DDS into Elixir to enable brokerless discovery and publish/subscribe; the demo spawns 5 publishers and 3 subscribers as Elixir processes and publishes joystick data. Nerves support uses a Docker-for-arm64 step that copies only the required ROS2 native libraries into the Nerves overlay so Rclex runs on constrained devices. For wide‑area links the team bridges DDS with the General pub/sub router (requires a router IP), and demos show messages crossing the Pacific via an Azure router.
