Thank You dear [hippo5329] !. I did the ultrasound sensor data publishes and also got range sensor cone on RVIZ. Only issue is costmap_2d is not forming when place any obstruction in front of USS. only the cone size is increasing / decreasing. what is next.
my navigation.yaml is as under, please guide further:

Indentation is very important in YAML. Please check your indentation. To show your code here, please fence your code blocks with three backticks (```) or three tildes (~~~) on the lines before and after the code block.

But the costmap is not forming on rviz with USS (RangeSensorLayer).
I need your help to complete my project please..., Thank you.

The order of plugins is important.

Dear sir, Thank you for your response .
I'm getting this warning on terminal continuously.:

the sequence is changed, however the message continuously on terminal is :
"No range readings received for --- seconds, while expected at least every 1.00 seconds" as in my code "no_readings_timeout: 1.0 " is there.
Further help please .
The topic must not be relative. topics: ["/ultrasound_FL"]
Please revert to "no_readings_timeout: 0.0".
And check "ros2 topic hz /ultrasound_FL".
Thanks for the tip!
I did : no_readings_timeout: 0.0
every thing is ok, no messages, but no costmap for sonar obstruction.
May I ask you please, your "sonar.launch.py" and sonar.node / package file /urdf file etc. etc .
Regards, Hem

What is the rate of "ros2 topic hz /ultrasound_FL" ?
Hi, Dear Thomas sir,
bringup.launch.py: Node( package='tf2_ros', executable='static_transform_publisher', output='screen', arguments=['0.0', '0.0', '0.0', '0', '0.0', '0.0', 'base_link', 'range_link' , '20' ]
if you permit I will post my hardware and ws directory.
thank you.

It might be a bug. I will look into this later. Thanks.
Hi ,
The bug is located on my .ino file .
changed Frame_id : "/range_link" to Frame_id : "range_link" in .ino hardware file, Now the costmap is working.
Thank you.
If anyone made a sonar range sensor with linorobot2 , please share the code to avoid obstacles. Regars, Hem.
