Hi, Pls run the rosmaster with the following command in a separate terminal.


And then try your

rosrun openni_tracker openni_tracker

I suggest you to go through the tutorials.

Hope this helps.

Thanks, Karthik

Ok are you able to run rosrun openni_camera openni_node? Are you having the problem only with this node. Check the other packages like turtlesim, gazebo.

well, I can run rosrun turtlesim turtlesim_node,......., rosrun rviz rviz,.......,rosrun image_view disparity_view image:=/camera/depth/disparity,.......,rosrun image_view image_view image:=/camera/rgb/image_color,...., however I can not run rosrun openni_tracker openni_tracker,.....,if I want to run the point cloud node, it must be like this rosrun image_view image_view image:=/camera/depth/points,,,,,right?

it seems your ROS installation is fine. But the openni_tracker has the problem. When you say nothing happens, is it with the above mentioned error or you see blank terminal with no msgs after you type the run command.?

Try checking the rostopic list and see if something is publishing. You can also check this with rxgraph.
