Hi. I'm trying to load the libCameraPublisher.so into gazebo5 but it gives me this error while spawning my robot: Actually I want to publish the camera's data into a ros topic.

[Err] [Model.cc:770] Model[MyName] is attempting to load a plugin, but detected an incorrect plugin type. Plugin filename[libCameraPlugin.so] name[camera_controller] Here you can see my .launch and model.sdf files:

Launch File:

<launch>
<!-- We resume the logic in empty_world.launch, changing only the name of the world to be launched -->
<param name="robot_description_sdf" textfile="$(find bring_up)/models/pioneer3at/model.sdf" />
