roslaunch astra_launch astra.launch doesn't work

edit

Everytime I run roslaunch astra_launch astra.launch command the camera starts up and after a couple of seconds it stops and the following message is being written to the console ->

[camera/driver-2] process has finished cleanly

log file: /home/turtlebot/.ros/log/edd078ce-b15b-11e6-8a2e-000c29a7eef6/camera-driver-2*.log

and the contents of the log file are as follows ->
