How to write rosrun rviz rviz -f velodyne into my launch file?
I'm trying to run rviz with my velodyne lidar puck and I'm confused how to write the code, specifically the argument to connect rviz to the velodyne.
I know that it is set up like <node pkg="rviz" type="rviz" name="rviz" args="___________________"/>
Thank you
