I’m assuming if we stick the fiducial images (QR Codes) on the floor, as opposed to the ceiling, and then if we could find a way to point the on-board RaspiCam down on the floor instead of up to the ceiling, would it amount to the same thing and work just as well?

I’m assuming downward facing camera should work, but wanted to ask since there is a setting in the /etc/ubiquity/robot.yaml file that explicitly sets the orientation of the camera to ‘upward’.

Also, does the camera mount have to be angled-down exactly 20° as opposed to 20° up?

Thx!
