Hello, gazebo answer.

I have been developing a robot with a projector. So I am using a projector simulation in GAZEBO. But I have a problem that it doesn’t work textureTopicNames.

I tried to change the texture image with the following command.

$ rostopic pub /ubiquitous_display/texture std_ms/String "data: 'pop_gazebo.png'"

However, the projected image by the projector does not change from the initially set “test.png”.

Is there a way to solve this problem?

  
    
      0 0 0 0 0 0
      test.png

      5.0
    
  
  
     
         projector_gazebo_optical_frame/ud_projector
         true

         test.png
         /ubiquitous_display/texture
         /ubiquitous_display/image
     
  

using GAZEBO-9 + melodic Thank you!
