Im trying to use nav2d package with turtlebot and kinect to map an unknown room. But I couldn't recieve /map from Mapper node.

as you can see on my rqt_graph: image description

tf frame: image description

I can't use /StartMapping 3 and /StartExploration 2. These are the /map and the /Operator/local_map/costmap in RVIZ. image description image description

It has costmap, but has no map.

Here is my launch file:

<!-- Some general parameters -->

<param name="use_sim_time" value="false" />

<rosparam file="$(find nav2d_tutorials)/param/ros.yaml"/>

What does echo $TURTLEBOT_MAP_FILE give?

Sorry that didn't have anything to do with nav2d package. However I see that you have done remapping from scan to base_scan even though your laser topic is scan in ros.yaml. Would you please comment out the 3 remappings in the launch file and try it again?

I have commented out the 3 remappings in the launch file, but it still has no map. I really don't know where is the problem caused in this way, thank you for your answer
