Hi Blaise,

Hokuyo model is : URG-04LX. I installed picocom, but after executing
 $ picocom /dev/ttyACM0
 ...........................................
Terminal ready

Now if I type VV [or vv] it reply with "C" . So don't know what the firmware
version is. from URG-04LX specifications it seems that it follows SCIP
version 2.

I have tested laser with player program and its working. Because of
modularity and distributed system I switched to ROS and just trying to make
an interface with powerbot [Pioneer]. I have tested p2os node [from USC] and
found it working. Expecting your help in this regards.
