Hi,
I am trying to create a global map for navigation with a Magni Silver according to the tutorials found at https://learn.ubiquityrobotics.com/fi…. When I use rviz to visualize and monitor my map creation, it gives me this error message: “Could not find a connection between ‘odom’ and ‘base_link’ because they are not part of the same tree.Tf has two or more unconnected trees”. On rviz, the image tab says “no image received” and the image window at the bottom left says “no image”. I believe the above error message is the root of the problem. Does anyone know how to fix this issue? Any suggestions and help would be greatly appreciated.
(The camera doesn’t seem to be the problem as it is able to detect the fiducial markers I had placed on the ceiling and is updating the map with the information.)
Below is a snippet of the output with the error message I am receiving:
