总结

前言

前面已经实现了在gazebo仿真环境中机器人一字型编队、三角形编队、N字型编队等仿真，接下来考虑多机器人编队在编队行进过程中的避障问题，通过在RVIZ中加载多个机器人使他们能分别进行全局和局部路径规划，来进行避障。

一、Gzazebo中加载多台Turtlebot3机器人

在前面的文章中也提到过在gazebo仿真环境中加载多个机器人主要是修改启动gazebo仿真环境的launch文件。
原Turtlebot3 launch文件

<launch>
  <env name="GAZEBO_RESOURCE_PATH" value="$(find turtlebot3_gazebo)/models/turtlebot3_autorace/ground_picture" />

  <arg name="x_pos" default="0.245"/>
  <arg name="y_pos" default="-1.787"/>
  <arg name="z_pos" default="0"/>  

  <include file="$(find gazebo_ros)/launch/empty_world.launch">
    <arg name="world_name" value="$(find turtlebot3_gazebo)/worlds/turtlebot3_autorace.world" />
    <arg name="paused" value="false"/>
    <arg name="use_sim_time" value="true"/>
    <arg name="gui" value="true"/>
    <arg name="headless" value="false"/>
    <arg name="debug" value="false"/>
  </include>  

  <param name="robot_description" command="$(find xacro)/xacro --inorder $(find turtlebot3_description)/urdf/turtlebot3_burger_for_autorace.urdf.xacro" />
  <node pkg="gazebo_ros" type="spawn_model" name="spawn_urdf" args="-urdf -model turtlebot3_burger -x $(arg x_pos) -y $(arg y_pos) -z $(arg z_pos) -param robot_description" />
   
</launch>

添加多台机器人的launch文件

<?xml version="1.0"?>

对比发现，修改后的launch文件增加了三个tb3的ns属性，并为其设置了初始位姿，设置了ns属性后才使得每个仿真小车发布带有对应属性的节点名称，例如/tb3_0/odom、/tb3_0/base_link、/tb3_1/odom、/tb3_1/base_link。这样能防止TF树错乱而导致的运行出错。

二、RVIZ中加载多个Turtlebot3机器人

与Gazebo中加载多个Turtlebot3机器人相比，RVIZ需要修改的内容多了些。首先修改turtlebot3_navigation.launch
原文件：

<launch>
  <!-- Arguments -->
  <arg name="model" default="$(env TURTLEBOT3_MODEL)" doc="model type [burger, waffle, waffle_pi]"/>
  <arg name="map_file" default="$(find turtlebot3_navigation)/maps/map.yaml"/>
  <arg name="open_rviz" default="true"/>
  <arg name="move_forward_only" default="false"/>

  <!-- Turtlebot3 -->
  <include file="$(find turtlebot3_bringup)/launch/turtlebot3_remote.launch">
    <arg name="model" value="$(arg model)" />
  </include>

  <!-- Map server -->
  <node pkg="map_server" name="map_server" type="map_server" args="$(arg map_file)"/>

  <!-- AMCL -->
  <include file="$(find turtlebot3_navigation)/launch/amcl.launch"/>

  <!-- move_base -->
  <include file="$(find turtlebot3_navigation)/launch/move_base.launch">
    <arg name="model" value="$(arg model)" />
    <arg name="move_forward_only" value="$(arg move_forward_only)"/>
  </include>

  <!-- rviz -->
  <group if="$(arg open_rviz)"> 
    <node pkg="rviz" type="rviz" name="rviz" required="true"
          args="-d $(find turtlebot3_navigation)/rviz/turtlebot3_navigation.rviz"/>
  </group>
</launch>

三.多机器人编队导航

多机器人编队的仿真在前面文章中叙述过：多机器人三角形编队的实现，编队的程序不需要修改，可以直接运行。
启动gazebo仿真环境(launch 自己的文件名)：

roslaunch turtlebot3_gazebo multi3_turtlebot3.launch
1

在这里插入图片描述
启动导航节点（RVIZ）

roslaunch  turtlebot3_navigation turtlebot3_navigation
1

在这里插入图片描述启动编队程序：

roslaunch turtlebot3_teams_wang  turtlebot3_teams_follow_wang.launch
1

在这里插入图片描述

总结

简单总结了Turtlebot3多机器人编队仿真，在实现的过程中需要对RVIZ仿真环境进行配置，这个花费了我很长时间，后面我会专门的写一下，主要是添加多个2D nav Goal/2D pose estimate，以及导航、laser、全局路径/局部路径话题的订阅。
