URDF unit 2 cannot open RVIZ

Hi there,
I was trying to follow the URDF tutorials but I am stuck on setting up to RVIZ.
The Robot model cannot recognize TF for some reason.
What can I do?


Take a look at the example image in the notebook. You see which frame is set? You have selected the wrong one ( map ). That frame doesn’t exist in that simulation and therefore TF can’t resolve ;).
