I get the error when I run rviz in course Programming Drone with ROS
How can I fix it?
Hi @huynhtancuongrus ,
You should change the Fixed Frame under Global Options in the Displays tab on the Left Panel of RViz to something like base_link or odom or world.
You will see a drop-down menu when you click on Fixed Frame. Choose the frame name with base_link or odom or world in it.

That should fix your issue.

Thank you so much !!!
