If you have had nightmares of dozens, if not hundreds, of intelligent drones swarming towards you, then perhaps ZANO is a nightmare come true, at least to some extent. The brain child of Torquing Group in the UK, ZANO is a nano drone smaller or just as small as the palm of your hand. It's small enough to take with you anywhere and whip out in an instant for a splendid shot. And it's smart enough to know where its going. All you really need is your smartphone.
