I am currently in Chapter 3 in the URDF course. I am facing problems with trying to visualize my robot mira in the rviz for some reason.
I tried copy and pasting the solution but the GraphicalTools are completely black screened and nothing pops out. Here’s a flow of what I did so you could possibly see what I did wrong;
# Execute in shell #1 roslaunch my_mira_description spawn_mira_geometric_collisions_inertias.launch # Output in terminal ... logging to /home/user/.ros/log/270bd63a-cf7d-11eb-945c-0242ac1c0008/roslaunch-3_xterm-11843.log Checking log directory for disk usage.

However, nothing emerges from the gazebo.
I also checked if mira is really spawned or not using :
rosservice call /gazebo/get_world_properties
…and mira is indeed there.
Can you point out what I did wrong?
