I think you're on the right track. But I wouldn't say that the action server "disables" the subscription, as much as it

I can't answer this question generally, but I will talk about what we do, which seems to be working pretty good for us.

The only time I see this is when I repeatedly use ctrl-c on my launch process. Typically if I use it once and let launch

If you only need to specify the order, then launch will already respect the order you specify nodes in. But if you need

The nmea_navsat_driver has already been ported to ros2. I've been using it under galactic just fine.

While I'm not the one who wrote this example code, I can still speculate. I think the demo is to show two main points:

RVIz in and of itself doesn't really know how to display the angle of an arbitrary joint. Typically you have a robot_sta

Not really a ros question... but you should always back-up your data prior to any major upgrade.
