I need help.
I tried this tutorial (link text), however I can see only black screen in rviz and the following error message is displayed:

[ WARN] [1339998294.058023439]: Message from [/hokuyo_node] has a non-fully-qualified frame_id [laser]. Resolved locally to [/laser]. This is will likely not work in multi-robot systems. This message will only print once.

When I tried rosnode hz scan, the following message is displayed:

  1. Ensure that your fixed frame in rviz is set to /laser (as shown in the picture in the tutorial).
  2. Scroll out (use mouse wheel) until you can see the whole grid. Sometimes you see only black because you are seeing only one portion of the grid

Thank you. I could see a map by scrolling out.

You should look at this tutorial and run the command below:

rosrun rviz rviz -d `rospack find hokuyo_node`/hokuyo_test.vcg

I hope this helps!
