Subscribed Topics

  • /mode (std_msgs/String)
    This topic indicates the next mode name. Modes can be defined in a yaml file (an example is below).

config file example

  • mode_list.yaml
mode_list:
    normal:
        launch:
            - pkg: your_robot_package
              file: /launch/your_robot_start.launch
              args:
                - name: mode
                  value: single_camera
                - name: is_device
                  value: false
            - pkg: your_navigation_package
              file: /launch/your_navigation_start.launch
              args:
                - name: mode
                  value: single_camera
                - name: explore
                  value: false
        keeping_node_patterns:
            - \/?explore.*
    make_map:
        launch:
            - pkg: your_robot_package
              file: /launch/your_robot_start.launch
              args:
                - name: mode
                  value: single_camera
                - name: is_device
                  value: false
            - pkg: your_navigation_package
              file: /launch/your_navigation_start.launch
              args:
                - name: mode
                  value: single_camera
                - name: explore
                  value: true

The example yaml config file above has two modes which equal to:

normal

  <include file="$(find your_robot_package)/launch/your_robot_start.launch">
    <arg name="mode" value="single_camera"/>
    <arg name="is_device" value="false"/>
  </include>
  <include file="$(find your_navigation_package)/launch/your_navigation_start.launch">
    <arg name="mode" value="single_camera"/>
    <arg name="explore" value="false"/>
  </include>

make_map

  <include file="$(find your_robot_package)/launch/your_robot_start.launch">
    <arg name="mode" value="single_camera"/>
    <arg name="is_device" value="false"/>
  </include>
  <include file="$(find your_navigation_package)/launch/your_navigation_start.launch">
    <arg name="mode" value="single_camera"/>
    <arg name="explore" value="true"/>
  </include>

launch

An array of launchfiles to launch. It consists of pkg, file, args.

  • pkg: The package name that contains the file to start
  • file: Relative path of the launch file to start
  • args: Arrays of arguments of the launch file to start

keeping_node_patterns

An array of node name regular expressions to keep when switching launchfiles.

Default keeping node patterns
  • \/?rosout
  • \/?rviz.*
  • \/?robomaker\/srv
  • \/?gazebo

Switch launch files

You can switch launchfile sending mode name topic.

rostopic pub -r 10 /mode std_msgs/String  'make_map'

will kill all existing nodes and launch the file below:

  <include file="$(find your_robot_package)/launch/your_robot_start.launch">
    <arg name="mode" value="single_camera"/>
    <arg name="is_device" value="false"/>
  </include>
  <include file="$(find your_navigation_package)/launch/your_navigation_start.launch">
    <arg name="mode" value="single_camera"/>
    <arg name="explore" value="true"/>
  </include>

launch file sample

  <node pkg="launchfile_switcher" type="launchfile_switcher" name="launchfile_switcher" output="screen">
    <rosparam file="$(find your_package)/config/mode_list.yaml" command="load" />
  </node>
