Revision history [back]

From rosgraph.png, it looks like the cost map of move_base is not linked to the map image.

If you change the global costmap yaml to the following, it should improve the problem.

global_costmap:
  global_frame: world
  robot_base_frame: base_link
  update_frequency: 5.0
  static_map: true

  resolution: 0.012270416 
  plugins:
    - {name: static_layer, type: "costmap_2d::StaticLayer"}

  static_layer:
    map_topic: "map"
