Info about /rosout topic and rosout node
Dear Members,
Hi Hope you guys are having a good one. I am very new to ROS and trying to understand the architecture. Until now I found it very fascinating and the community is doing a great job. I was looking at different nodes and topics and where I am stuck currently in understanding properly the /rosout topic and rosout node. I have been through the wiki.ros.org but did not understand it completely. That would be great if anyone here can shed some light on it and explain it to me in a more simpler way.
Sincerely, muscles
Hey, welcome! Have you seen this? http://wiki.ros.org/rosout Sorry, I re-read your question. Now I understand you went through that specific page, didn't you?
Dear Javier,
Yes I have been through this specific page wiki.ros.org/rosout , but still did not completely understand why do we need rosout and what's the purpose of using it .
Sincerely,
Well, I haven't used it at all, but I can imagine an use case: usually you print info on terminal. What if you cannot see this terminal? Then you store it to a file. If you publish to rosout, this is done transparently, and you have timing info, can store it in a rosbag, reproduce it, etc.
