I don’t understand what you mean. Can you describe this in more detail with some image if necessary?

i have a video submitted above(.webm).here are two more image.in the first ,when global path has two right-angle corner,robort will stop.in second is a provided gazebo map with two small change(added two walls). when i set a goal behid walls,which will make a global path with two right-angle,as image 3 robot will stop at the first corner.as 4 but when i break the whole global path into two,one goal at the first corner,one at the final goal.it works well.as 5&6&7 and then i set goal at origine point,it still stop.as 8&9 i have try to change the parameters in cost map and controller_server yesterday.it makes no use .above situation in images i changed nothing in code and parameters.

Have you made an attempt to tune the controller? Which are you using and what are its parameters?
