What type of fiducial markers is being used? like what is the name of the ones which are used in the tutorial?
Your comment makes me realize we should state that we use the Aruco style of fidicial patterns on our learn page so I have updated the page.
I have also added a very brief paragraph on how we use the aruco_detect node and then use topics it publishes to do our map making and navigation.
Update is here: https://learn.ubiquityrobotics.com/fiducials
Thanks for the input.
