Hi I make a autonomous differential robot. In kinetic devel navigation stack works fine. Robot can get position, goes goal, escape obstacle....However i upgrade my linux and ros base to melodic devel.

In melodic devel i get the error. My robot doesn't avoid from obstacles.I cant solve this... Is there any solution?

Warning: Invalid argument "/laser" passed to canTransform argument source_frame in tf2 frame_ids cannot start with a '/' like: at line 134 in /tmp/binarydeb/ros-melodic-tf2-0.6.5/src/buffer_core.cpp

I solved the problem. In laser scanner package, frame name is "/laser"... I ommit the "/" then it works

I have the same issue. Could you please elaborate a little bit more on this. I get issues while I'm trying to run the TEB local planner.

You are somewhere defining the frame as /frame_name. But, since ROS Melodic (probably, I'm not sure) you have to define it as frame_name. Just change your configuration file and will work properly
