Many aerial drones now feature a Follow Me mode – that’s where they can be instructed to autonomously fly along above you and shoot video as you ski, cycle, run or otherwise move about. However, what happens if you’re a scuba diver? Well, in the near future, you might buy an iBubble. It’s a submersible drone that tracks its user as they swim underwater, using a proprietary technique that combines echolocation and object recognition.
