I don't get any data (rgb image,depth image,rviz) from the kinect,I'm running on Ubuntu 10.10 ,diamondback;basically what I did is :

1) I set up my computer to accept software from ROS.org

2) I ran roscore on a new terminal by typing : roscore

3)I installed openNI kinect by typing : sudo apt-get install ros-diamondback-openni-kinect

4)I installed openNi camera by typing : rosmake openni_camera

5)I launched the openNI driver by typing :roslaunch openni_camera openni_node.launch

6)I ran rviz by typing: rosrun rviz rviz

7)I ran the rgb camera by typing : rosrun image_view image_view image:=/camera/rgb/image_color

Where did you get these instructions from? These are not the standard wa to install the kinect drivers.

If you would like to view images coming from the kinect camera, follow the instructions posted here: http://www.ros.org/wiki/openni_kinect and here: http://www.ros.org/wiki/openni_camera

which are summarized as follows:

  1. install openni_kinect: sudo apt-get install ros-electric-openni-kinect
  2. run openni: roslaunch openni_launch openni.launch
  3. run image viewer: rosrun image_view image_view image:=/camera/rgb/image_color

First, pasting half of the web into your question doesn't help.

What's this KinectROSPackage thing you're talking about? You should just install openni_kinect from the binaries:

sudo apt-get install ros-electric-openni-kinect

and then use the various nodes it provides.

Do you see the IR-Laser of the Kinect actually turning on when you subscribe to any of the depth-related topics?
