ros Map_server could not open map

edit

Hi,

Could use some help on this one.

This one works on my robot (I copy the map files manually to the /tmp directory before roslaunching it):

 <launch>

      <!--- Run the kinect -->
      <include file="$(find turtlebot_bringup)/kinect.launch" />

      <!-- Run the map server -->
      <node name="map_server" pkg="map_server" type="map_server" args="/tmp/my_map_waalre.yaml" />

      <!--- Run AMCL -->
      <include file="$(find turtlebot_navigation)/config/amcl_turtlebot.launch" />

      <!--- Run Move Base -->
      <include file="$(find turtlebot_navigation)/config/move_base_turtlebot.launch" />

    </launch>

But this one not and comes with error

<launch>

  <!--- Run the kinect -->
  <include file="$(find turtlebot_bringup)/kinect.launch" />

  <!-- Run the map server -->
  <node name="map_server" pkg="map_server" type="map_server" args="/home/turtelbot/fuerte_workspace/sandbox/robo/my_map_waalre.yaml" />

  <!--- Run AMCL -->
  <include file="$(find turtlebot_navigation)/config/amcl_turtlebot.launch" />

  <!--- Run Move Base -->
  <include file="$(find turtlebot_navigation)/config/move_base_turtlebot.launch" />

</launch>

So same file but just in a different directory. I must be overseeing something simple. error it produces:

process[map_server-8]: started with pid [20619] process[amcl-9]: started with pid [20630] process[move_base-10]: started with pid [20679] [map_server-8] process has died [pid 20619, exit code 255, cmd /opt/ros/fuerte/stacks/navigation/map_server/bin/map_server /home/turtelbot/fuerte_workspace/sandbox/robo/my_map_waalre.yaml __name:=map_server __log:=/home/turtelbot/.ros/log/531236a0-7aaf-11e3-8077-94dbc9f717d5/map_server-8.log]. log file: /home/turtelbot/.ros/log/531236a0-7aaf-11e3-8077-94dbc9f717d5/map_server-8*.log

Any clues?

Thanks
