turtlebot3_gazebo package not publishing on /scan
I am launching a Gazebo
world using roslaunch turtlebot3_gazebo turtlebot3_world.launch
. However, when I run the command rostopic echo /scan
in the terminal window, I get the following message -
WARNING: no messages received and simulated time is active.
Is /clock being published?
How can I make Gazebo
publish to /scan
?

Did you change any thing on turtlebot repo or it is orginal because if you changed something on urdf maybe you can deleted scan options

I deleted the entire
turtlebot3
package, and re-built it from source. Same issue. It is weird because everything was working fine a couple of days ago.Asked by skpro19 on 2020-12-27 10:10:50 UTC
Firstly you can check tf tree. Also I want to ask one more question. Does your simulation work or it gives some error ?
