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:
 * /robot_tf_listener:
   * /robot_tf_listener/costmap/footprint
   * /tf_static
 * /rviz:
   * /move_base/global_costmap/costmap_updates
   * /move_base/local_costmap/costmap
   * /move_base/local_costmap/costmap_updates
   * /projected_map_updates

   * /tf_static
   * /map
 * /pointcloud_to_laserscan:
   * /cloud_in
   * /tf_static
 * /rgbdslam:
   * /tf_static

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.
