I am trying the package of "navigation_tutorials-indigo-devel", the package and it works well on simulation but on the robot it gives the following message:

[ WARN] [1524062750.418983315]: No laser scan received (and thus no pose updates have been published) for 1524062750.418840 seconds. Verify that data is being published on the /scan topic.

did you verify that data was being published on the /scan topic? Could you provide more details on what robot you're using? Is it a TurtleBot? Does it have a Kinect? Are you using pointcloud_to_laserscan to create the /scan?
