Robot does not show up on gazebo

I am going through the first robot course and I have got to the point where you can should see the robot in gazebo. I cannot see it. I can see it rviz though. I haven’t modified anything - I was following the course and when it all works, I will modify.

Here is the message :

If I go into graphical tools I see nothing.

What stupidity have I done ?

Hi, welcome to the community! Are you getting errors inside the course or a rosject? You shouldn’t have to launch simulations in the course, they are available for you when you open them. If you are in a course, which unit is it?

If there are no errors in the simulation, maybe it’s a visualization issue, so try to see if by moving the camera around and see something. If not, try restarting your rosject. But again, I don’t know if you are doing this in the course or a rosject.
