I'm trying the mir100 mobile manipulator simulation using this package:

https://github.com/dfki-ric/mir_robot

The issue occurs when I type the following commands to simulate the mapping of an unknown space in gazebo:

### gazebo:
roslaunch mir_gazebo mir_maze_world.launch
rosservice call /gazebo/unpause_physics   # or click the "start" button in the Gazebo GUI

### mapping:
roslaunch mir_navigation hector_mapping.launch.xml

So far so good, this is where it goes wrong:

# navigation:
roslaunch mir_navigation move_base.xml with_virtual_walls:=false

I get the following error:

RLException: [/home/beau/catkinws/src/mirrobot/mirnavigation/launch/movebase.xml] requires the 'local_planner' arg to be set

This is what the file mentioned in the error contains:

  1 <launch>

 24         <remap from="marker" to="move_base_node/DWBLocalPlanner/markers" />
 25     </node>
 26 </launch>

So I thoughts there must be something wrong with line 11:

$(arg local_planner)_local_planner_params.yaml

So I went to look in the yaml files: https://github.com/dfki-ric/mirrobot/tree/melodic/mirnavigation/config

The one named: mirlocalplanner_params.yaml contains a line:

  dwa: true

Should I set the argument manually somewhere?
