在胡春旭123页运行launch文件时遇到的问题

问题：

ERROR: cannot launch node of type [robot_state_publisher/state_publisher]: Cannot locate node of type [state_publisher] in package [robot_state_publisher]. Make sure file exists in package path and permission is set to executable (chmod +x)

解决办法：

将mrobot_description功能包下launch文件夹中display_mrobot_chassis_urdf.launch这个launch文件里面的运行robot_state_publisher节点下的type由type="state_publisher"改为type=“robot_state_publisher”，再一次运行display_mrobot_chassis_urdf.launch这个launch文件，就可解决问题。
