Hi. I'm trying to use NAO laser head with urg_node, but there is connection problem. I'm trying to connect with Ehternet and always have same problem

 [FATAL] [1397748302.090283298]: Could not open network Hokuyo:
could not open ethernet port.

Also i used different ip-diapason address: default,, there is no connection to laser. (to connect laser use NAO ip, default ip ( as said here) What i'm doing wrong?

Do you have details about the Nao laser head you are using? I'm pretty sure that the Hokuyo laser is not connected via ethernet but a serial device over USB (the only one I know with the URG04LX is definitely not network-enabled). So you can't connect to it over network. Instead you need to cross-compile hokuyo_node or urg_node for the Nao and run the driver locally on the robot.
