This is in URDF for Robot Modeling section 3, 1.4, I am not being able to spawn the mira robot the service times out without the model appearing in Gazebo. I have tried to reload the simulation. The code used is as given in the notes.
"Spawn status: SpawnModel: Entity pushed to spawn queue, but spawn service timed out waiting for entity to appear in simulation underthe name mira"
Update: Gazebo is also not opening in Graphical Tools when running:
cd ~/catkin_ws source devel/setup.bash roslaunch simulation_gazebo main.launch
