custom frames
How do I go about making my own frame in ROS? I do not know where "/world" frame comes from and I want to relate my own custom frame to world. I see frame ID's but I do not where the "/world" is initialized.

How do I go about making my own frame in ROS? I do not know where "/world" frame comes from and I want to relate my own custom frame to world. I see frame ID's but I do not where the "/world" is initialized.
TF frame names are implicit. If the frame_id in the Header of a message is set, the data is published in that frame. If you manually enter that frame name in Rviz's World Frame
, you will be able to visualize the data from your publisher without needing to do any additional TF setup.
The /world
frame is simply the default frame name in Rviz; it doesn't come from anywhere else.
If you have TF publishers or nodes that publish TF like robot_state_publisher, Rviz will auto-populate the World Frame
dropdown with the names of the frames that is has seen recently.

4 frame positioned relative to each other
Hokuyo doesn't publish a frame,Error: Ingoring transform for child_frame_id "laser_2"...
RViz error:Transform [sender=unknown_publisher] - For frame [X]: Frame [X] does not exist
How can I save four consecutive frames of a camera?
TF - Transform world frame update rate should be fastest
RVIZ not displaying /scan frames
Have you tried the
tf
tutorials?yes and no luck there.
