Entity pushed to spawn queue but does not spawn in simulation

I’m having an issue with section 1.4 Spawn into Simulation. I have run the following command:

roslaunch my_mira_description spawn_mira_simple_collisions_inertias.launch

and I get the following output:

SpawnModel script started
[INFO] [1574821021.621107, 0.000000]: Loading model XML from ros parameter

The model never appears in Gazebo. I have tried resetting the simulation but I still get the same output. Any help would be appreciated.

Hello @acis.ubc,

May you send me your package/s so that I can check if there’s something wrong? You can send them to aezquerro@theconstructsim.com

Best,

Hello ,
I too have the same issue. I have been trying to figure it out for a whole day. Should I send in my package/s too?

Could you send us the files? duckfrost@theconstructsim.com. Also the command that you use to reproduce this issue and the unit where this happens. Thanks

I also had this problem @staff how can I solve this issue?

Thaks in advance
