The <arg>
XML tag syntax is sometimes confusing. Note that it can be either a declaration or an assignment.
To declare an <arg>
, put it almost anywhere in the file before using the $(arg)
substitution variable.
To assign a value, nest it within the <include>
tag, or pass it to the top launch file via a parameter to roslaunch
.
