Hi

After some nice discussion with the navigation community we figured out a
way how to deal with the shared parameters using roslaunch variables:

Have a look at:


<launch>

  <arg name="robot_name" default="r1" />
  <arg name="room" default="gh25" />
  <arg name="env" default="sim" />
  <arg name="scan" default="front_laser/scan" />


   <!-- Mapserver -->
  <include file="$(find v4r_launch)/launch/map.launch">
     <arg name="room" value="$(arg room)" />
     <arg name="env" value="$(arg env)" />
   </include>

  <!-- Navigation -->
  <group ns="$(arg robot_name)">
    <include file="$(find v4r_launch)/launch/amcl.launch">
      <arg name="scan" value="$(arg scan)" />
      <arg name="robot_name" default="$(arg robot_name)" />
    </include>
    <include file="$(find v4r_launch)/launch/move_base.launch">
      <arg name="scan" value="$(arg scan)" />
      <arg name="robot_name" default="$(arg robot_name)" />
    </include>
  </group>

</launch>

---------------- File: $(find v4r_launch)/launch/amcl.launch
--------------------
<launch>

  <arg name="robot_name" default="r1" />
  <arg name="scan" default="front_laser/scan" />

  <node pkg="amcl" type="amcl" name="amcl" output="screen">
    <remap from="scan" to="$(arg scan)"/>
    <remap from="map" to="/map"/>
    <rosparam file="$(find
v4r_launch)/cfg/amcl/marry_real/amcl_filter.yaml" command="load"/>
    <rosparam file="$(find
v4r_launch)/cfg/amcl/marry_real/amcl_laser_model.yaml" command="load"/>
    <rosparam file="$(find
v4r_launch)/cfg/amcl/marry_real/amcl_motion_model.yaml" command="load"/>
    <param name="odom_frame_id" value="$(arg robot_name)/odom"/>
    <param name="base_frame_id" value="$(arg robot_name)/base_link"/>
    <param name="global_frame_id" value="/map"/>
  </node>


</launch>



---------------- File: $(find v4r_launch)/launch/move_base.launch
--------------------
<launch>

  <arg name="robot_name" default="r1" />
  <arg name="scan" default="front_laser/scan" />

  <node pkg="move_base" type="move_base" name="move_base"
output="screen">
    <remap from="scan" to="$(arg scan)"/>
    <remap from="map" to="/map"/>
    <rosparam file="$(find
v4r_launch)/cfg/move_base/bader3dx/common_costmap.yaml" command="load"
ns="global_costmap" />
    <rosparam file="$(find
v4r_launch)/cfg/move_base/bader3dx/common_costmap.yaml" command="load"
ns="local_costmap" />
    <rosparam file="$(find

    <rosparam file="$(find
v4r_launch)/cfg/move_base/bader3dx/local_costmap.yaml" command="load" />
    <rosparam file="$(find

/>
    <param name="TrajectoryPlannerROS/global_frame_id" value="$(arg

    <param name="global_costmap/global_frame" value="map"/>
    <param name="global_costmap/robot_base_frame" value="$(arg

    <param

    <param name="local_costmap/global_frame" value="$(arg
robot_name)/odom"/>
    <param name="local_costmap/robot_base_frame" value="$(arg
robot_name)/base_link"/>
    <param

value="$(arg robot_name)/front_laser"/>
  </node>
