Error when running rtabmap_ros with turtlebot3

Hello everyone, I had a problem when I tried running rtabmap_ros with turtlebot3, my terminal existed a warning:

I couldn’t launch rtabmap_ros (mapping mode)

Hello @nguyenphucvuongcdt ,

You are trying it with Turtlebot3? So, are you outside the course? In that case, make sure that the topics are updated to match the ones for Turtlebot3 (since the regular Turtlebot used in the course uses different topic names).


thank you for your replying, I am outside the course. I want to apply the course into my project with turtlebot3. I checked my topics and found that they were like with topics in the course.
