    <xacro:ray_sensor sensor_name="${name}" gazebo="${gazebo}" 
                  update_rate="62.0" visualize="1" 
                  h_samples="640" h_res="1.0" h_min_angle="${-pi}" h_max_angle="${pi}" 
                  r_min="0.164" r_max="12.0" r_res="0.01">
                  <plugin name="dummy" filename="dummyfile"></plugin>

  </gazebo>

Should we correct plugin name and filename?

Hi @AltinayGrass Can you please confirm the PC hardware you are running the simulation on? do you have a GPU?  Please provide package versions, an example of data and/or error and screenshot from Gazebo including the visualization of the lidar rays.

Thank you, Rusty

Hi RustyCPR,

Thank you for your questions, I think that these are for solving my problem. However I still haven't got an answer to my question. Can you please confirm whether "dummy" means nonfunctional or need to be filled?
