I am using astra depth camera and a kinect under same ros master but on different robots. Could someone please tell how to run multiple cameras on same master? [closed]

edit

I am using astra_launch package for astra cam and freenect_launch for kinect. When I try to launch both the cameras simultaneously, both the processes die and no topics are being published. I have already tried remapping the topics of astra camera but it is still not working. Steps:- 1. roslaunch astra_launch astra.launch 2. rostopic list /b1/camera/depth/camera_info /b1/camera/depth/image /b1/camera/depth/image/compressed......... like this 3. roslaunch freenect_launch freenect.launch 4.
