Can anyone describe, in detail, the parameters involved in the launch file. I combed through the tutorials and the descriptions are not that adequate?

Is there an example you can point me to as well that call 3 or more packages/nodes? The type and name parameters have me at a slight loss...

I am trying something like: <launch>

<node respawn="true" pkg="joy" type="joy" name="rov_joy" &gt;="" <param="" name="dev" type="string" value="/dev/input/js0"/> </node>

</launch>

@101010 Can you elaborate on what are you trying to accomplish ? If you read a launch file completely then most of the issues are sorted out.

There are a number of launch files in ROS projects on Github. That would likely be a great place to find some real-world examples to help you out:

You can look at this tutorial to see a simple example of several concepts, including the use of launch files for C++ and Python nodes with parameters (launch file links are near the end).

Ah, got it, nevermind, I found the answer. I was using the wrong package name and type.
