篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了ROS2初学者教程(Dashing和Eloquent)Windows相关的知识,希望对你有一定的参考价值。
初学者(入门级)教程是分步说明ROS2使用的资料汇总,目标向初学者介绍ROS 2。建议按顺序学习这些教程,从“普通用户”课程过渡到“开发人员”课程,获取ROS 2的基本知识。

如果正在寻找特定的教程内容,欢迎从教程中挑选对应课程,需要了解这些教程是相互关联的或独立的,但是并不意味着这是全面的文档。这些教程正在逐步完善中,因此欢迎反馈。
注意:当前,初学者级教程针对Dashing和Eloquent。某些功能可能不适用于较早的发行版。
学习此部分教程,并不需要ROS1基础,也不推荐学习ROS1相关内容,直接在ROS2环境下开发机器人功能包。
turtlesim示例
rviz2示例
ros2 topic pub --rate 1 /turtle1/cmd_vel geometry_msgs/msg/Twist "linear: x: 2.0, y: 0.0, z: 0.0, angular: x: 0.0, y: 0.0, z: 1.8"
ros2 service call /spawn turtlesim/srv/Spawn "x: 6, y: 1, theta: 1.2, name: t6"
ros2 param set /turtlesim background_r 255
ros2 action send_goal /turtle1/rotate_absolute turtlesim/action/RotateAbsolute "theta: 1.57"

部分调试记录:
ros2 run turtlesim turtlesim_node
This application failed to start because it could not find or load the Qt platform plugin "windows"
使用windeployqt,配置一下该节点,通用格式如下:
windeployqt <ros2>/install/Lib/<package>/<target>.exe
