Sadly I know very little about about ROS considering I'm personal friends with one of the maintainers. One of the more exciting things about nerves is that they are making it "easy to do the right thing" in terms of using end to end encryption for all of the parts of your nerves network when you deploy. I would say that ffi on elixir is... Hard. Not impossible. (I'm currently writing a zig ffi library that aims to make it as painless as inlining the ffi code) If you're an abject beginner at both elixir and robotics I don't recommend going beyond what nerves has to offer off the shelf. If you're an expert in one of either the underlying robotics c interfaces or elixir, I think writing your own ffi might be neat and worth giving a go. The documentation on how to do things isn't terrible.
