I can't see hokuyo_node information on rviz.
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:
