These tiny drones would be small enough to sit on your shoulder or fit in your pocket, the patent says, and a lot of the processing required by the devices would be offloaded to the cloud to keep them small and nippy.
Keep droning on
It sounds like the controls would be largely automatic and voice-driven - so you would tell the drone what you wanted it to do rather than fishing out a remote control. No doubt Amazon's is going to be involved somewhere down the line too.
These pocket drones could be used to track down lost property, check where you parked at the shopping centre or even keep an eye on your kids if they've got a tendency to wander off, Amazon says.
As with any patent application, it's only a sign of what a company is thinking about, and there's no guarantee this will ever become a real product. Still, Alexa in a drone is an idea that has a certain appeal to it.
