Provide CLI roslaunch with XML <group> tag.
I would like to perform a roslaunch from the command line which replicates the < group> tag from the XML roslaunch syntax.
Is this possible?
For example, say I wanted to run the a launch file, spawnmavrosinstance.launch, which creates the following topics:
/topic1
/topic2
...
With the roslaunch XML format I could create a launch file with the
<launch>
<group ns="uav1">
<include file="$(find ardupilot_gazebo)/launch/spawn_mavros_instance.launch">
<arg name="fcu_url" value="udp://127.0.0.1:14551@" />
</include>
</group>
</launch>
which creates topics with the following namespace:
/uav1/topic1
/uav1/topic2
...
I am using ROS Melodic on Ubuntu 18.04.

are you asking how to
roslaunch
a.launch
file in a namespace?If so: you should be able to do that using
ROS_NAMESPACE=<your_namespace> roslaunch ...

Thank You

Alternatively you could also add an argument to the launch file for the namespace.
You could just do
roslaunch ardupilot_gazebo mavros_namespace_instance.launch name:=uav1
and just replace the argument in the command line.Asked by Reamees on 2019-12-10 03:47:57 UTC
