I need to include a small box (static) object in a .world file that has a **picture** in it. (I have .launch and .world file that works fine) I am new to ros and gazebo. I am little bit confused with all the model files (.dae, .model, .urdf, etc). How can I create a small box shape with a picture in it and how to include that in a .world file? Do I need to create a model in blender or sketchup and export it to .dae? I don't have a clear idea of how .dae, .model, .urdf files works together.
