Background

Hi, I am trying to use move_base_flex to replace move_base so I am using move_base_flex with the move_base_legacy_relay node.

Problem Statement

When I publish a /move_base_simple/goal message I am running into an error:
[ERROR] ... The last action goal to "get_path" has been REJECTED
and a warning:
[ WARN] ... No plugin loaded with the given name "navfn/NavfnROS"!

Initial Debug Notes

  1. Locating the package navfn
    When I run:
    rospack find navfn
    this returns
    /opt/ros/melodic/share/navfn
  2. I am able to use move_base fine which also relies on the navfn package

Environment

Ubuntu 18
Melodic
Robot is Simulated
Mapping and Localization with slam_toolbox

Output

Here is the entire output from running the move_base_flex node:

... logging to /root/.ros/log/ec5c7112-2396-11eb-818a-04ed33dd081a/roslaunch-hopper-1849.log

Launch File and config files##

I modeled the launch and config files from https://github.com/uos/ceres_robot/tree/master/ceres_navigation

Here is my launch file for mbf:

<?xml version="1.0" ?>
<launch>

  <node name="map_server" pkg="map_server" type="map_server" args="$(find thor_robot_launch)/maps/map.yaml" ns="global_costmap" clear_params="true"/> 
  
  <node pkg="mbf_costmap_nav" type="mbf_costmap_nav" respawn="false" name="move_base_flex" output="screen">
    <param name="tf_timeout" value="1.5"/>
    <param name="planner_max_retries" value="3"/>
    <rosparam file="$(find thor_robot_launch)/config/robots/grover/planners.yaml" command="load" />
    <rosparam file="$(find thor_robot_launch)/config/robots/grover/controllers.yaml" command="load" /> 
    <rosparam file="$(find thor_robot_launch)/config/robots/grover/costmap_common_params.yaml" command="load" ns="global_costmap" /> 
    <rosparam file="$(find thor_robot_launch)/config/robots/grover/costmap_common_params.yaml" command="load" ns="local_costmap" />
    <rosparam file="$(find thor_robot_launch)/config/robots/grover/local_costmap_params.yaml" command="load" />
    <rosparam file="$(find thor_robot_launch)/config/robots/grover/global_costmap_params.yaml" command="load" /> 
    <remap from="/cmd_vel" to="/cmd_vel/move_base" />
  </node>
  
  <node name="move_base_legacy_relay" pkg="mbf_costmap_nav" type="move_base_legacy_relay.py"/>

</launch>

I have attached my config files if those are helpful
planners.yaml.txt
controllers.yaml.txt
costmap_common_params.yaml.txt
local_costmap_params.yaml.txt
global_costmap_params.yaml.txt

Any help would be greatly appreciated.
Thanks,

The default global planner is

base_global_planner (string, default: "navfn/NavfnROS")

But this is not listed in planners.yaml
Either add it to the config file or set the bgp variable in the move_base_legacy_relay.py

Hi Sebastian,

Firstly thanks for the quick reply yesterday. As you suggested, the solution was to add to the planners.yaml:

  - name: 'navfn/NavfnROS'
    type: 'navfn/NavfnROS'

In addition to that I also added to the controllers.yaml:

  - name: 'base_local_planner/TrajectoryPlannerROS'
    type: 'base_local_planner/TrajectoryPlannerROS'

However, I found a bug with the move_base_legacy_relay node with the bgp, blp, and parameters. When setting up the dynamic reconfigure server in this line the MoveBaseConfig is used and overwrites all parameters including bgp, blp. I made a hack fix by only changing bgp and blp when they are set to None, but the rest of my parameters were still overwritten.

I am willing to make changes and submit a PR, but I want to know your thoughts.

Dean

Hi @dean4ta, not sure if I get the latest problem, but,,, what you said is correct, that is, that line triggers a first call to reconfigure that will use all the parameters that you define under 'move_base' namespace. So if you choose a base_local/global_planner, it will be added there:

Otherwise, the fields will contain the default values:
