How to detect when move_base is executing recovery behaviors
Hi all,
My problem is the following. When a robot is stuck and move_base
is not able to find a valid plan I can see on rqt_console
the corresponding ERROR and WARN messages:
In this case, there's no path to the goal and move_base
starts its recovery behaviors.
My question is: if I want to write a simple subscriber that is able to detect this situation (e.g. so that it can warn somehow the user) to which topic should I listen and how can I intercept this message?
Thanks.
