Have you check the permission of serial port?

ll /dev/ttyUSB*

If the permission is not to be read,

sudo chmod 666 /dev/ttyUSB*

After that,you can start to run the sample. terminal 1:

roslaunch rplidar_ros rplidar.launch

terminal 2:

rosrun rplidar_ros rplidarNodeClient

And the terminal 2 will show the rplidar scanner's data.
