Guys, I need help...so I'm trying to implement Hokuyo URG-04LX laser scanner to hector SLAM.
I've downloaded hector SLAM from github (URL: https://github.com/tu-darmstadt-ros-pkg/hector_slam.git ) and followed tutorial from http://wiki.ros.org/hector_slam and it works but when i try to use Hokuyo URG-04LX for mapping without odometry by running hector_slam node,hokuyo node and rviz, but it didn't show anything...can anyone help or is there a reference? i'm very new to ROS...thanks before
