movebase: choose local path planner

edit

hi, all,

to choose local path planner for move base, i.e. DWA or trajectory rollout. is it sufficient to make the choice in local path planner parameters, like

TrajectoryPlannerROS:
  dwa: false
  heading_scoring: false

is it necessary to make the choice in move_base parameters it self?

  <node pkg="move_base" type="move_base" respawn="false" name="move_base" output="screen">
    <param name="base_local_planner" value="TrajectoryPlannerROS"/>
