rgbdslam navigation [closed]
Hi I worked with turtlebot distro hydro, i want to navigate my robot with rgbdslam so i roslaunch my turtlebot ,openni+rgbdslam, octomap_server, move_base, but after when i did roswtf i found this warning:
WARNING The following node subscriptions are unconnected:

so these nodes are subsribed to topics that no one is publishing to,I noticed that the tf_static topic is present in all these nodes. but i didn'tt understand what is this topic and which node is the reponsable to publish it.
I really need your help, Thanks in advance
it looks like your move_base does not start properly. You should check in rqt first.
