[ROS]學習ROS_urdf/Tutorials/Using urdf with robot_state_publisher 時遇到的問題

按照官網的教程：http://wiki.ros.org/urdf/Tutorials/Using%20urdf%20with%20robot_state_publisher

學習的時候，在最後launch的時候出現了error：ERROR: cannot launch node of type [r2d2/state_publisher]: can't locate node [state_publisher] in package [r2d2]

最後在這位大神的回答中找到了答案：

就是在CMakelist.txt中添加：

catkin_package()
