Hallo, can someone please tell me where to find the package turtle_tf2 mentioned in this tf2 tutorial: http://wiki.ros.org/tf2/Tutorials/Introduction%20to%20tf2

I have just switched to ROS hydro (Ubuntu 12.04).

Regards, David

Hallo,

I am using a Kinect mounted on a PR2, ROS Electric and the openni_camera package from the openni_kinect stack. After starting the Kinect driver with

• rgb_frame id: /openni_rgb_optical_frame and
• depth_frame_id: /openni_depth_optical_frame

the published clouds both have the frame_id /openni_rgb_optical_frame.

Has someone an explanation for me?

Thanks David
