ROS中launch详解记录

ROS中的launch文件主要用于多个节点的配置与启动,launch是后缀为.launch的xml文件

1、使用方法

1 roslaunch package_name launch_file_name

2、launch文件的标签

  2.1 launch标签

1 <launch>
2 ...
3 </launch>

  2.2 node标签

  其中“SUBscriber”为ros节点的名字,“subscriber”为功能包的名字,“exeSubscriber”为生成可执行文件的名字,“output”是否输出到屏幕上!

1 <launch>
2     <node name = "SUBscriber"  pkg = "subscriber"  type = "exeSubscriber"  output = "screen"/>
3 </launch>

  2.3 include标签

  1、使用方法

  include标签相当于嵌套语句,用于把另外一个launch文件导入当前的launch文件,只需要执行publisher.launch,SUBscriber节点也会启动。

<launch>
    <node name = "PUBlisher"  pkg = "publisher"  type = "exePublisher"/>
    <include file = "$(find subscriber)/launch/subscriber.launch"/>   #include 的使用方法
</launch>
