No point cloud in Turtlebot Gazebo gmapping
I'm trying to follow this tutorial with Gazebo simulator:
http://learn.turtlebot.com/2015/02/01/11/
In the tutorial, (real) Turtlebot is scanning the environment with Kinect point cloud. But when I run the examples in the turtlebot_gazebo package, it only scans with a fake laser. Probably because of this node, in the launch file of example:
Anyway, how can I add the Kinect point cloud scan to that example?
