Question

Hi, all. I am trying to mount a laser (hokuyo UTM-30LX-EW) on a Kobuki (i.e. turtlebot 2). The power of laser is supplied by the Kobuki itself. This driver (urg_node) from ROS is used. The kobuki is controlled by my laptop. My laptop is being on the internet by a wireless WiFi network. However, when I input:

roscore
rosrun urg_node urg_node _ip_address:="192.168.0.10"

I get the following error:

[ERROR] [1427377404.083261181]: Error connecting to Hokuyo: Could not open network Hokuyo:
192.168.0.1:10940
could not open ethernet port.

I have searched answers.ros.org and couldn't get an efficient answer. Please tell me how to solve this problem. Thanks.

Answer 1

I found the answer. The same problem has been solved here. I thought the setting of static IP was under wireless network. Since the laser is connected to laotop by wired network, setting the static IP of the port of network card is enougth.
