Problem with Hokuyo UTM-30LX-EW. [closed]
Hi, I want use a laser Hokuyo UTM-30LX-EW in ROS Hydro and Ubuntu 12.04. This laser, uses ethernet connection. I tried urg_node link text and urgwidget-wrapper, but when I connect the laser and run my launch file, I have this error:
[ERROR] [1393842815.953332067]: Error connecting to Hokuyo: Could not open network Hokuyo: 192.168.0.10:10940 could not open ethernet port.
This is my launch file:
<launch>
<node pkg="urg_node" type="urg_node" name="urg_node" output="screen">

I edited my Ubuntu connection:
IP Address 192.168.0.10
Subnet Mask 255.255.255.0
Default Gateway 192.168.0.1
If I run ifconfig -a in Ubuntu:

I think that this problem is but the Ubuntu config, something problem with the port or similar, but I don´t know as resolve it. Thanks.
I close this answer because I have the solution. SOLUTION: Configuration Ubuntu network: IP Address 192.168.0.15 Subnet Mask 255.255.255.0 Default Gateway 192.168.0.1 Best regards.
