Stefan,  

   Nice work!  

What does it take to convert the hector_slam demo to run with the
hokuyo_node?

I've cut/pasted my attempt to modify the mapping_box.launch file below,
which is the only one starting up Hokuyo, but no point cloud appears.  I
suspect that one of the required initial transforms is not being
published.  Can you help?   Thanks
