ROS user interface for non-ROS machine

Hi, I want to build a application which runs on a non-ROS machine (Windows computer for example) and can communicate directly with ROS so that I can monitor and control my robot remotely. I found that ros-bridge is a usual way to do such applications but I don't really similar to web-based. Is there any other way to so? I would prefer solutions in C++ language. Both ROS1 and ROS2 solutions will be considered since my robot is currently running on ROS1 and I have a plan to switch to ROS2 in the future. Please give me some advice. Thank you!

I would still recommend to use rosbridge, unless you have very big messages and high rates.

For coordination type UIs, there are C++ clients available, see #q385152 fi (which is almost the first result if you search for rosbridge c++). For other languages there are other options (roslibpy fi).

In general this seems to be getting into an XY problem. https://xyproblem.info/ https://meta.stackexchange.com/questi... aka you're asking how to run a ROS interface on a "non-ROS" machine. But as soon as you run a ROS interface on the non-ROS machine it's not non-ROS.

What I think you want to do is run a c++ gui on a windows machine that can interact with the ROS network. You can build applications with ROS libraries inside them that include all the necessary libraries to be distributed as a standard Windows C++ executable to install on a Windows system.

Compiling into a self contained executable allows you to run on a standard windows installation without setting anything else up such as the developer toolchains etc. And this is actually possible on any platform but is particularly useful on Windows where self contained binaries are more expected.

Yes, that is exactly what I meant. But then how can I interact with ROS network as well as read ROS msgs? It seems like this contains a lot of work.

If you've compiled the ROS client libraries into your application it can talk with the ROS network via ROS messages.

But it requires TCPROS/UDPROS to communicate be able to communicate with ROS nodes, doesn't it? And also how can my application present in the ROS network? On ROS machine we easily do that by export ROS_MASTER_URI and ROS_HOSTNAME but what about non-ROS machine? Does it require to include anything else?

TCPROS and UDPROS are implemented in the client libraries. Those environment variables are read and used by the client library. Thus if you compile in the client libraries your application, the application can talk with the ROS network.
