why didn't the cartographer published /map?
Hi! I want to use google's cartographer in my turtlebot3 robot.but no /map published. print following warnning:
[ WARN] [1501071021.570063704]: W0726 20:10:21.000000 14280 tf_bridge.cc:51] Invalid argument passed to lookupTransform argument source_frame in tf2 frame_ids cannot be empty

^CWarning: Invalid argument passed to canTransform argument source_frame in tf2 frame_ids cannot be empty

why?
I may not be able to help much, but if you could post more information it would help others debug this issue. Could you post your tf tree, your configuration file (.lua) and launch file that you've used?
Also, it may be worth creating an issue in the Cartographer google groups, and linking back to here.
