What computer are you running rviz on?

I'm sorry, I don't quite understand what you mean, Are you asking how to improve localization during SLAM or how to do l

AMCL needs a map in order to localize the robot. A common tactic is using gmapping to create this map, save it using map

I've copied your setup and it works fine for me. Maybe you're not setting up rviz correctly? What do you mean by "only s

My /map -> /base_link transform is provided by AMCL. Changing the origin didn't fix the issue. I tried out your test

I suggest you start with the ROS tutorials: http://wiki.ros.org/ROS/Tutorials to get the hang of how the workspace works

Have you been able to follow the steps in the readme up until the compile step? Do you have a catkin workspace? If so,

With regards to the import error, you'll have to post the code you're tying to run.

Having to source the workspace is not a bug, it's intended behaviour. Say you have multiple workspaces, you only want to

Just in case, do you have a RobotModel display active in RViz?

After switching to the plugin implementation of costmap_2d in order to be able to work with layers, the layers load extremely slowly and in chunks, it's a bit difficult to explain, so I've included pictures:

Using pre-hydro configuration:

Using plugins:

It's a problem since it also affects the planners.

Here are my config files:

costmap_common_params.yaml:

  obstacle_range: 3.5
  raytrace_range: 4.0
  robot_radius: 0.4
  inflation_radius: 0.7

  obstacle_layer:
    observation_sources: laser_scan_sensor
    laser_scan_sensor: {sensor_frame: /sensor_link, data_type: LaserScan, topic: /navbot/scan_data, marking: true, clearing: true}

global_costmap_params:

global_costmap:
  global_frame: /map
  robot_base_frame: /platform
  update_frequency: 5.0
  static_map: true
  plugins:
    - {name: inflation_layer,   type: "costmap_2d::InflationLayer", output: "screen"}
    - {name: static_map,        type: "costmap_2d::StaticLayer"}
    - {name: obstacle_layer,    type: "costmap_2d::ObstacleLayer", output: "screen"}

local_costmap_params.yaml:

local_costmap:
  global_frame: /map
  robot_base_frame: /platform
  update_frequency: 8.0
  publish_frequency: 4.0
  rolling_window: true
  static_map: false
  width: 6.0
  height: 6.0
  resolution: 0.05
  plugins:
    - {name: inflation_layer,        type: "costmap_2d::InflationLayer", output: "screen"}
    - {name: obstacle_layer,         type: "costmap_2d::ObstacleLayer", output: "screen"}

Thank you.

Thank you, I'll try it out on Monday and update the question. EDIT: That solved the problem, thank you again.
