move_base extracts the current position from tf. what is the name of the frame it subscribes to relative to /map frame?
move_base
actually gets the current position from the costmap (see here).
Thus, you specify the the frame_id
in the costmap config file via the ~<name>/robot_base_frame
parameter, which defaults to base_link
.
As you write correctly, it uses tf to get the current position, so it does not subscribe to a topic other than tf
for this.
