Hello
After the first command, roslaunch summit_xl_demo navigation_with_gps.launch i have the following error
[ WARN] [1586814266.536397228, 358.268000000]: Timed out waiting for transform from base_link to map to become available before running costmap, tf error: canTransform: target_frame map does not exist. canTransform: source_frame base_link does not exist… canTransform returned after 0.1 timeout was 0.1.
Note that curiously when i start RVIZ , one rviz screen is already open then i get a second one ???
When i look at the topic list, it is looking there is 2 robots ( or components have been added an not attached to URDF or static TF added ?? )
I moved forward unit 2 that uses the same robot. And i have not been able to do the exercises also.
