Unable to run the RVIZ visualization

[GiulioRomualdi]

I'm trying to run the RVIZ visualization located in whole-body-estimators/devices/baseEstimatorV1/ros
The command I'm using is roslaunch fbeViz.launch
An I'm getting the following error.

roslaunch fbeViz.launch 
... logging to /home/gromualdi/.ros/log/8762f73a-50ca-11ea-ab11-9cb6d0f6860f/roslaunch-iiticublap109-23145.log

RLException: Invalid <arg> tag: iCub

ROS path [1]=/opt/ros/melodic/share. 

Arg xml is <arg default="$(find iCub)/robots/$(env YARP_ROBOT_NAME)/model.urdf" name="model"/>
The traceback for the exception was written to the log file

I'm pretty sure I'm making some mistakes (I'm not a ROS user 😢 )

Can you help me? cc @prashanthr05

@GiulioRomualdi please excuse for the lack of documentation on the visualization using RViz. I will update it.

However, I feel rusty with the code as well. I need to look into it and try to fix it if its missing some crucial parts.

I suppose, the solution depends on where the repository icub-models is installed. Could you make sure that ROS_PACKAGE_PATH points to where icub-models is installed?

Probably we need to add ROS_PACKAGE_PATH to the env variables exported in the superbuild's env variables scripts.

I think the issue is with the command you're writing, try using this command:
roslaunch <package name> <launch file>

@GiulioRomualdi one quick check is to use roscd to check if ros can correctly discover your ros-package, in which you have the launch file. Let me know if you need a hand to run rviz.
