hi , i'm trying to launch move_base backage and i used this launch file :

<launch>
<node name="map_server" pkg="map_server" type="map_server" args="$(find flo_navigation_rviz)/maps/couloir_hopi.yaml" output="screen"/>

<include file="$(find amcl)/examples/amcl_diff.launch" > </include>
<node pkg="move_base" type="move_base" respawn="false" name="move_base" >
<rosparam command="load" file="$(find flo_navigation_rviz)/param/costmap_common_params.yaml"  />
<rosparam file="$(find flo_navigation_rviz)/param/costmap_common_params.yaml" command="load" ns="local_costmap" />
<rosparam file="$(find flo_navigation_rviz)/param/local_costmap_params.yaml" command="load"/>
<rosparam file="$(find flo_navigation_rviz)/param/global_costmap_params.yaml" command="load" />
<rosparam file="$(find flo_navigation_rviz)/param/base_local_planner_params.yaml" command="load" />
</node>
</launch>

i get this error :

error loading <rosparam> tag: 
    file does not exist [/home/kesuke-pc/catkin_ws/src/flo_navigation_rviz/param/costmap_common_params.yaml]
XML is <rosparam command="load" file="$(find flo_navigation_rviz)/param/costmap_common_params.yaml" ns="global_costmap"/>

The traceback for the exception was written to the log file

i put "costmap_common_params.yaml" in the folder named "param" i dont understand why rosparam can't find it ?? thanks in advance for all your answers

Have you "sourced" your workspace when you opened a new terminal/tab?

Sorry, but I have no idea why roslaunch can't find your file... Maybe is a silly question, but, is the whole path correct?

roscd find it so i don't think there is a problem with the path

Just to be sure, try:

gedit <the-whole-path-to-the-file>/<file-name>.yaml

Does it find it?
