the package "clearpath_kinect" subscribe to the topic "idfloor_in" with the message type "sensor_msgs/PointCloud2",and I run the node "openni_node" which has the same message type as the topic "idfloor_in",so I changed "idfloor_in" to "openni_node" so that they can connect with each other.And then the window running the node ClearpathDemoExplore shows : BAD INITIALIZATION, NORMAL FAILED, TRY AGAIN Do I have mistakes when using the package "clearpath_kinect"?

That particular demo package automatically calibrates the position and orientation of the Kinect relative to the ground. Due to this, it requires you to have a reasonable amount of flat ground within the field of view of the Kinect on startup for the initialization to succeed. How do you have the Kinect positioned with respect to the ground?

Thank you.I set the Kinect in the wrong way.But now it has a warning:Iteration of vision loop took ** seconds (max is 0.100000),which is larger than 0.100000.And the data on the topic idfloor_out_vel is a set value: tw.linear.x =0, tw.angular.z =-0.3. Can you tell me why?

What platform are you using this with? There's also a "height from floor" parameter.
