聲明：本插件依賴于更新的qt5.9，不需安裝qt，安裝插件自行安裝qt。詳情見點擊打開鏈接

1、創(chuàng)建工程

最后點擊完成即可。

2，建好后右鍵點擊src，打開Terminal，執(zhí)行指令建包catkin_create_qt_pkg btn

（預先安裝建包工具，指令：sudo apt-get install ros-indigo-qt-ros）

這就建立

這就建好一個包了，點擊左下角小錘子編譯一下，通過。

3、然后點擊project->run,添加節(jié)點如圖：

4，在UI界面拖放幾個按鈕，并改名字，右擊按鈕轉到槽，在主窗口cpp文件中寫入qnode.up（）;（因為qnode里面定義的是up和left）,另一按鈕同理。

5主要的是qnode.cpp文件，首先在頭文件中定義

然后寫qnode.cpp文件

PS：1、頭文件包含問題：

用插件創(chuàng)建或導入ROS package之后還需要修改.workspace文件，

在<IncludePaths>標簽下加入下面這行

<Directory>/opt/ros/indigo/include</Directory>

• 1

這樣就可以使得Qt找到ros頭文件，比如<ros/ros.h>?

2，connect前一定要、一定要在use environment variable前打鉤或者輸入ROS IP。

在此非常感謝我的小伙伴的幫助。
