Hi, im new to Gazebo, would you tell me, How the rexrov find these sensor plugins? I check the source code, but i don't find which codes use the sensor plugins~ Thank you!

when you install gazebo-ros, some default plugins are available to used. The library or .so file is inside the system. But if you create your own plugin from the package itself, you may see it in the .so files in "devel/lib" of your workspace.
