rviz doesn't display urg-04lx-ug01 data
With the following code I tried to use the hokuyo laser but in rviz there's nothing , and I can't select the frame laser .
<launch> <node name="urg_node" pkg="urg_node" type="urg_node"> </node> <node name="rviz" pkg="rviz" type="rviz" args="-d $(find laser_visualization)/config/laser_demo.rviz"/> </launch>
