Thank you stefan,
after detecting Qrcodes i need to mark objects in map by hector_object_tracker.
i have added object_tracker in my launch file, and i am using your rqt_rescue plugin in this address:
irrw2012/source/browse/trunk/rqt_rescue_control_plugin/lib/RescueControlDialog.py#59
but when i click on "Add victim in front of robot" button, in running launch file terminal, it prints this line:
[ INFO] [1370900109.430975931]: add_object service called for new victim object in frame base_link
and in rqt termianl it prints:
service call failed
and after saving maps, no mark added to the map.
what should i do in this situation?
