How to navigate?

[ashwinv96]

Hi,
Once I receive fiducial information, how can I use the topics of aruco_detect and fiducial_slam to navigate my robot specifically using MAVROS? Thanks!

Hi @rohbotics can you provide any support with this? Been stuck here for a while. I thank you in advance.

When I try to run the fiducial_follow (follow.py) example, I get this:

ConnectivityException: Could not find a connection between 'base_link' and 'fid103' because they are not part of the same tree.Tf has two or more unconnected trees.
Could not get tf for fid103
Errors: forward 0.000000 lateral 0.000000 angular 0.000000
Speeds: linear 0.000000 angular 0.000000
zero True True

This is after changing my fiducial of interest to fid103.
