ROS URDF(二): 控制URDF机械臂模型运动：解决URDF模型不随joint_states运动问题

继上篇文章ROS: URDF自定义robot model -----解决WARN：No tf data. Actual error: Fixed Frame [base_link] does not exist，继续研究URDF，利用joint_state_publisher 控制URDF机械臂模型运动。

建模参考：https://blog.csdn.net/wxflamy/article/details/79235493

1 创建urdf文件模型 myfirstrobot.urdf

2 创建launch启动文件diaplay.launch

3 启动launch文件

roslaunch myurdf display.launch

显示如下结果：

通过Joint State Publisher控制关节运动，如下

如上图，URDF模型并没有随着Joint State Publisher控制运动，变化的仅是tf frame.

经研究，发现该问题源于Rviz配置文件，当前启动的是rviz的默认配置，使用如下配置，可以实现URDF的随动，

5 更新launch文件

6 启动launch文件

roslaunch myurdf display.launch

如上，URDF模型随Joint State Publisher控制运动，且tf一起变换。
