why there is no transform to anything in rviz ？

[Tcoloi]

There are no error messages in terminal but in Riz there is no transform to anything in rviz and nothing shows up.

Try by checking the tf tree and seeing if anything looks unusual. If you're still having issues then can you provide more context on which commands you're executing and how you're launching Rviz.

I edited the husky launch file to add some laser configurations since there was no ros topic called “mid/points” and I still don't know what it is, I can't find the publisher of it. So I used the "/velodyne_points" instead.


When I am checking the TF tree, it seems that the problem occurs between the transformation from base_footprint to base_stabilized.

In Rviz the status of base_footprint is OK while the status of other parts keeps swiching between OK and Not OK. Is that because the frequence being to low? but I don't know how to edit the Broadcaster: /msg_to_tf to fix this.

Nope， I'm still figuring it out.

I finally solved it. Find the line

<arg name="enable_ekf" default="$(optenv ENABLE_EKF true)"/>

in husky_control/launch/control.launch and set it false to disable the EKF, it may make the TF tree unstable.

Does the navigation work? Or you just can't see the yellow point cloud as it is shown in the pic.

I can't visualize /trav_map in rviz, have you ever encountered such a problem?
