按照教程，很不幸出现了如下错误：
ERROR: cannot launch node of type [usb_cam/usb_cam_node]: usb_cam
ROS path [0]=/opt/ros/kinetic/share/ros
ROS path [1]=/opt/ros/kinetic/share使用这个解决

You need to a add a source file in your bash.rc
OR
Open the following directory in the terminal /home/gpslab/catkin_wsorb/
and type the following command
source devel/setup.bash
On the same terminal cd to your launch directory i.e. /home/gpslab/catkin_wsorb/src/usb_cam/launch/
and roslaunch the file
roslaunch usb_cam-test.launch
