I attached the RGB camera plugin to the px4vision SDF file, and I was able to see the camera in Gazebo when I do **make px4\_sitl gazebo-px4vision** , and when I do ros2 topic list, I cannot see that the camera is publishing data .

> $ ros2 topic list  
> /parameter\_events  
> /rosout

```auto
     <sensor name="camera" type="camera">
        <pose>0 0 0.1 0 0 0</pose>
