I need help for using the spawn_model within the rxgraph. My launch, my urdf. My simulation. Unfortunately, spawn_model node is not created within the rxgraph.

I'm not sure about this, but I guess the node is destroyed right after the model is published to gazebo... This launch command probably only makes a single ros service call...

Hi evilBiber, this is it, but is it normal? For you also happen this?

I have also this error: Warning [] No <sdf> element in file[data-string] Warning [] parse from urdf. Could this be my problem?

As @evilBiber suggests, spawn_model is intended to exit right after creating the model. That's probably happening too quickly for the spawn_model node to ever appear in rxgraph.

It looks to me like it's operating properly.
