ROS2 course project: Unable to run the simulation

I’m starting the course project but in step 2, it tells me to execute the following commands:

source /opt/ros/noetic/setup.bash
source ~/simulation_ws/devel/setup.bash
roslaunch realrobotlab main.launch

However, it throws this error many times
Missing model.config for model [and here it specifies all the locations of the missing models].
How can this problem be solved?

Hi @MMartinez-HAW ,

It looks like a warning that gazebo uses to output when models don’t follow a specific definition in its files.

Although, this should not prevent you from having the simulation running.
Have you checked if gazebo opened normally?


It opened but it didn’t load anything.

Hi, one more important thing.

In the notebooks there should be the instruction that the zoom is too close to the floor, sometimes.

Please, could you try zooming out from the simulation window?

If that is not the case, maybe gazebo is not running properly.
Could you send a screenshot to help me understand what is happening there?
