I am willing to run the simulation provided for Kalman Filter course in my local PC. My os is Ubuntu 18.04 and Ros distro is Melodic
I have downloaded the project files. But It is not working correctly. when I am trying to run roslaunch kalman_filter launch_auxiliary_nodes.launch, it is giving me errors like
[INFO] [1608330989.930892]: Loading model XML from file /home/marzan/kalman_ws/src/kalman_filter/models/brick_box_3x1x3/model.sdf

When I have checked rostopic list, I have found some topics are publishing here. I am really confused about the necessary steps to overcome this situation. It would be really helpful for me if someone suggest me about the necessary steps.
