Hi, I have created a node in gazebo about logical camera

so when i type gz topic -l in terminal.

there is /gazebo/default/my_p3dx/base_link/logical_camera/models.

and i want to use this values in ros.(When i type rostopic list in terminal, there ins't /gazebo/default/my_p3dx/base_link/logical_camera/models message)

I guess that send from gazebo topic to ros topic, How can i do that?

Hi @Colin you get a solution to this?

I am trying to do a similar thing with python library named pygazebo with combination of rospy. The straightforward solution is probably writing a gazebo plugin for this purpose.

For my understanding you would like to republish a topic in Gazebo to ROS. If this is what you are trying to do, see this example.

The official way make Gazebo and ROS interact is implementing a Gazebo plugin, there are different types of plugins in Gazebo depending on what you are trying to publish (model, sensor, etc.). However, in case that you have some problems to implement that the other approach could be used. Explanation of how to create a plugin could be see here.
