I assume that you could somthing wrong to add publisher on your code.

Can you attach your code?

I launched roscore on my Laptop running Ubunutu 16.04. Then I login to my turtlebot (RaspberryPi 3b (no plus)) and run following:

$ roslaunch turtlebot3_bringup turtlebot3_robot.launch

The code for turtlebot3_launch is in updated description above.

Is this what you are looking for?

For everyone else - I found what the problem was. I did not have nav_msgs package installed. By downloading it from github into src folder and re-running catkin_make on turtlebot3, the problem was solved. This issue can be closed.

Hi, I'm having the same problem. Could you tell me where you downloaded the nav_msgs file? I looked at github but couldn't find it.
