I'm trying to do SLAM-mapping using a Turtlebot. The kinect works, but RVIZ doesn't recieve any data from it. I have the following errors:

error 1 (in dashboard):

Node: /rviz_1326231834235022764 Time: 1326233463.821563932 Severity: Warn Location: /opt/ros/electric/stacks/geometry/tf/include/tf/message_filter.h:MessageFilter::checkFailures:481 Published Topics: /rosout, /initialpose, /move_base_simple/goal

MessageFilter [target=/map ]: Dropped 100.00% of messages so far. Please turn the [ros.rviz.message_notifier] rosconsole logger to DEBUG for more information.

error 2 (in rviz): Camerainfo

No camerainfo recieved on camera/depth/camera_info]. Topic may not exist.

Error 3 Sometimes I get this error in dashboard:

Camera Info for rgb stream has subscribers, but stream has stopped.

Any ideas?

This looks like a message version mismatch between the computer running rviz and the turtlebot. Are you running the same version of ROS on both?

Thanks, that worked! I'll put it an answer below. Thanks for your great help!

This could also be a problem with your choice of coordinate frames in rviz. If your fixed or target frame isn't valid, rviz will fail to find a transform from the the camera frame to your target frame, so it displays nothing. Try choosing a different frames.

Thanks for the suggestion! But I am running electric on ubuntu 11.10 on both master and slave.

Apparently I messed around with rviz settings too much. After I set fixed_frame to /base_link and target Frame to in .Global Options, everything worked as expected. You can set the options in the rviz window or in .rviz/config and .rviz/display_config.
