Hokuyo UTM-30LX-EW not detected in Ubuntu or PC
Hi,
I am a newbie user for ROS. I am trying to run the Hokuyo UTM-30LX-EW LiDAR (with ethernet connection) using urg_node on Ubuntu 12.04 with ROS-Groovy.
When I run the following commands (in separate terminal windows)
roscore
rosrun urg_node urg_node _ip_address:="192.168.0.10"
I get the following error:
[FATAL] [1368644464.256278611]: Could not open network Hokuyo:
192.168.0.10:10940
could not open ethernet port.
Sadly, I also cannot get the tools issued by the manufacturer to detect the LiDAR when I try to connect in a Windows environment.
For both these situations, the laser scanner is switched on and connected when this happens. Also, the LEDs are lit steady after blinking for a few seconds on connection.
Can someone please provide me suggestions about what might be going on? Our lab spent a lot of money buying this equipment and I would like that to be put to good use!
Thanks in advance :-)
You are correct, the urg_node will not work if there is no connectivity to the laser. Setting the IP address of the computer to match that of the laser should resolve your problem.
