How to list the parameters of a node and the value of that parameter?
When I read the launch files written by others, I found that the node parameters they used were not listed in the wiki.
I am not sure about the role of these parameters and their initial values.
Is there any way to list these parameters and their values?
Can you please provide more details or even better an examaple what you are looking for ?
I found a way. For example, when I start a node, I can view the parameters of the node through the command
rosparam list.
