hi,

I want to run gmapping on turtlebot so i started with the basic turtlebot tutorials when i bringup the turtlebot and run the kincet.launch file the data published by kinect on /camera/depth/points is wrong also when i try to see the depth image using image view it's all black but when i run openni.launch file form the openni_launch package the kinect is publishing correct point cloud, ss there any problem with kinect.launch file in turtlebot_bringup I am using fuerte on ubuntu 12.04. this is my kinect.launch file

<launch> <node pkg="turtlebot_node" type="kinect_breaker_enabler.py" name="kinect_breaker_enabler"/>

<node pkg="nodelet" type="nodelet" name="pointcloud_throttle" args="load pointcloud_to_laserscan/CloudThrottle openni_manager" respawn="true"> <remap from="cloud_in" to="/camera/depth/points"/> <remap from="cloud_out" to="cloud_throttled"/> </node>
