What are the roles of <param> tags within the <node> tags in launch file?
Hi everyone, I wanna know what the roles of tags within the <node> tags are. Let's take a common example:
<node pkg="robot_state_publisher" type="robot_state_publisher" name="robot_state_publisher">
<param name="publish_frequency" type="double" value="30.0"/>
</node>
Please explain to me. Any answer is appreciated.
Have you checked the wiki ?
Yes, I did check the wiki. But I still can't comprehend the concepts of the naming rules about parameters in ros, so that I am disable to understand what the
<param>
tags within the<node>
tags mean.
