move_base not using base_local_planner_params.yaml [closed]

edit

Hi. Could someone please help me control cmd_vel published by move_base. And also get rid of some warnings and errors..

The move_base publishes velocities for x upto 0.55 which would be the default. I am just not able to reduce the velocity. what am I missing here ? Is there anything specific I must do so that move_base honors the base_local_planner_params.yaml, besides including it in the launch file ?

I have the following base_local_planner_params.yaml

 TrajectoryPlannerROS:
  max_vel_x: 0.2
  min_vel_x: 0.05
  max_rotational_vel: 0.7
  min_in_place_rotational_vel: .2
  escape_vel: -0.2

  sim_time: 1.7
  sim_granularity: 0.05
  path_distance_bias: 0.6
  goal_distance_bias: 0.6

  acc_lim_th: 3.2
  acc_lim_x: 1.0
  acc_lim_y: 1.0

  holonomic_robot: false

  yaw_goal_tolerance: 3.14
  meter_scoring: true

  dwa: true

The following is a section of the output.
