To do before merging:

• Undo car beacon on visual landing exercise
• Change QRs with aruco markers in the packages (package delivery)
• Use Aruco instead of apriltag on turtlebot. Or get back to green plate.

Hi Pedro, I tested the package delivery exercise with Qr code from this commit bbb3db9

the QR code when translated using this

        detector = cv2.QRCodeDetector()
        GUI.showImage(img_frontal)
        GUI.showLeftImage(img_ventral)
        
        data, bbox, _ = detector.detectAndDecode(img_ventral)
        
        if data:
            a=data
            print(a)

translates to "(20,20)" This data can be used for coordinates more appropriately than Aruco makers which only give the Marker ID. I tested this in the exercise and it was detected and decoded just fine (see console).

Here's the updated solution for the exercise (sometimes it is not able to find the delivery place even though the coordinates are correct:

EDIT: On repeated testing, I find that sometimes it takes quite a while to detect a QR Code.
