2017-03-14 13:13:14 -0500 asked a question How can I make a Parrot Bebop drone follow another Parrot Bebop ?

I'm trying to do a project with Parrot Bebop Drones. I was thinking of making one of the Parrot drone the publisher. So it would publish the directions that its taking and make the second Parrot drone the subscriber and execute the directions the first Parrot drone it doing. Any Tips on where to start or if this even possible.
