Hi

I like to connect ROS2 nodes via a wireguard vpn network. Is this possible?

I got it working and prepared an example on github Using Eclipse Cyclone DDS, but one has to set some variables export

Is it possible to run ROS2 via wireguard Hi I like to connect ROS2 nodes via a wireguard vpn network. Is this possible?

Hi I more or less rewrote stage_ros as stage_ros2. It differs from the previous stage_ros interfaces in its modularity.

Hi

I am not happy with the view on my scene after I start gazebo using rosrun with gazebo and my world file.

How can I set the initial view on my scene for the gazebo simulator.

Thanks and Greetings Max

It worked for me on Ubuntu 22.04 with ROS2 Humble.

Hi!
I like to launch gazebo with different environments (world files). But I only want to give as argument the world file name and not the full path. The full path should be created by launch file.

How can I use a LaunchArgument to create a full file name. The following statement in the IncludeLaunchDescription is not working.

launch_arguments={'world': pkg_tuw_gazebo + '/worlds/' + LaunchConfiguration('room') + '.world'}.items(),

Thanks in advance

There's the full code python launch file.

    room_arg    = DeclareLaunchArgument('room', default_value=TextSubstitution(text='roblab'))
    pkg_gazebo_ros = get_package_share_directory('gazebo_ros')
    pkg_tuw_gazebo = get_package_share_directory('tuw_gazebo')
    pkg_tuw_gazebo_models = get_package_share_directory('tuw_gazebo_models')

    if 'GAZEBO_MODEL_PATH' in os.environ:
        model_path =  os.environ['GAZEBO_MODEL_PATH'] \
            + ':' + pkg_tuw_gazebo_models + '/models'
    else:
        model_path =  pkg_tuw_gazebo_models + '/models'

    return LaunchDescription([
        room_arg,
        SetEnvironmentVariable(name='GAZEBO_MODEL_PATH', value=model_path),
        IncludeLaunchDescription(
            PythonLaunchDescriptionSource( os.path.join(pkg_gazebo_ros, 'launch', 'gazebo.launch.py')),
            # This is working, but I like to substitute cave in cave.world with my argument
            #launch_arguments={'world': os.path.join(pkg_tuw_gazebo, 'worlds', 'cave.world')}.items(),  
            # This is NOT working, I don't know how to access the room argument?
            launch_arguments={'world': pkg_tuw_gazebo + '/worlds/' \
                + LaunchConfiguration('room') + '.world'}.items(),
        ) 
    ])

I am getting the Error:

I like to use LaunchArgument to process my xacro file, which contains my robot model for gazebo and the robot_description for my robot_state_publisher.

I found a solution using the OpaqueFunction. Arguments are now evaluated and set in the create_robot_description which
