roslaunch can't find 'resource' and says file doesn't exist
Working through this tutorial on navigation package: http://wiki.ros.org/navigation/Tutori... I built the launch files as directed. The first one launches OK. The second one fails.
Launch file with issue:
<launch>
<master auto="start"/>
<!-- Run the map server -->
<node name="map_server" pkg="map_server" type="map_server" args="$(find catkin_ws)/map.pgm map_resolution"/>
<!--- Run AMCL -->
<include file="$(find amcl)/examples/amcl_diff.launch" />
<node pkg="move_base" type="move_base" respawn="false" name="move_base" output="screen">
<rosparam file="$(find my_robot_name_2dnav)/costmap_common_params.yaml" command="load" ns="global_costmap" />
<rosparam file="$(find my_robot_name_2dnav)/costmap_common_params.yaml" command="load" ns="local_costmap" />
<rosparam file="$(find my_robot_name_2dnav)/local_costmap_params.yaml" command="load" />
<rosparam file="$(find my_robot_name_2dnav)/global_costmap_params.yaml" command="load" />
<rosparam file="$(find my_robot_name_2dnav)/base_local_planner_params.yaml" command="load" />
</node>
</launch>
