[ros-users] Costmap_2d_tutorials without stageros?

[Daniel Maier]

Hi!

I think about using costmap_2d in one of my projects so I played around  
with the costmap_2d_tutorials.
Is it possible to run the costmap without stageros?
Here is a launch file I use for bringing up a costmap:

<launch>
   <param name="/use_sim_time" value="true"/>
   <node pkg="costmap_2d_tutorials" type="costmap_test" respawn="false"  
name="costmap_test" output="screen">
     <rosparam file="$(find nav)/costmap_params.yaml" command="load"  
ns="costmap" />
   </node>
   <!--
   <node pkg="stage" type="stageros" name="stageros" args="$(find  
2dnav_stage)/worlds/willow-pr2-2.5cm.world" respawn="false" >
     <param name="base_watchdog_timeout" value="0.2"/>
   </node>
   -->
</launch>

If I include the stageros node everything works as expected (I guess).
If I don't, the laserScanCallback in costmap_2d_ros.cpp is not being  
called.

Here is my costmap_params.yaml file:
