rosout node and rosout topic
According to wikiros tutorials and my ros textbook, the node rosout
subscribes to the topic /rosout
, takes the messages, records them in a textual log file.
My inference from this explanation is some nodes publish some messages to the topic /rosout
, and the node rosout
records them in log file. In this point, a question comes to my mind:
which nodes publish messages to the topic /rosout
?
Can any node publish a message to the topic /rosout
?
