UR5机器人学习之TCP/IP通讯

最近因为项目原因在研究UR机器人，主要是通过PC上位机与UR通讯，采用TCP/IP通讯的方式，PC上位机通过发送UR脚本指令实现控制机器人和操作机器人。

IP地址：可以根据UR机器人控制终端读取到IP地址

端口：端口取30001或者30002或者30003,（本实验使用的是30002端口）

脚本指令可以直接从官网下载，也可以从相关CSDN帖子材料中获得，或者联系我QQ：476596998

服务器：UR5

客户端：PC上位机

注意事项：

1、连接好时，URScript 程序或命令以清晰文本形式在每一个 socket 端口发送。每行均以“\n”结束。在编程的时候务必确定最终发送的文本中的格式为：命令（参数）\n

本人是以QT5.6来编写的上位机程序：如下所示：
