Because the notion of automated flying robots delivering dog food to your doorstep is something straight out of the Jetsons, it sort of makes sense that Amazon has a very retro vision for the towers that could house its Prime Air delivery drones.

The company filed a patent for a “multi-level fulfillment center” that’s designed “to accommodate landing and takeoff of unmanned aerial vehicles (UAVs), possibly in an urban setting, such as in a densely populated area.”

The patent drawings show a number of varieties that we’ve just gone ahead and given more accurately descriptive names to, like the one we’re calling either the Beehive or the Conehead:

Or the one that looks like an exurban apartment tower that was built for bachelors in 1967 but now houses all those lonely aunts and uncles whose families never visit them:

Then there’s this one that looks like a roll of toilet paper, or perhaps an Apple HomePod:

Here’s basically the same design, but covered in polka dots, like everything you bought at Target in 2004:

Finally, there’s this truly Jetsonian design that we’re just calling the Smiling Mushroom:

The company notes that unlike traditional fulfillment centers, these towers could have several levels — depending on local zoning regulations — and one or more landing/deployment areas where drones could pick up or drop off packages.

They’d also be servicing sites that would allow drones to charge or get a replacement battery, get inspected or serviced, or other operations that might be required between flights. These centers could possibly support old-fashioned deliveries by common carriers using ground vehicles, and include a self-service space where customers could pick up items stored in lockers or other temporary storage.

Amazon claims in its patent that the ML fulfillment center could be used to complete hundreds or thousands of orders each day using UAVs for at least some of those orders.

As such, it’ll be a busy place with lots of drones buzzing around, so there could be a central command “to control at least some operations of the UAVs, which may be analogous to a flight controller at an airport.”

We’re still a long way from the reality of drones winging their way homeward across a city skyline, of course, as the Federal Aviation Administration’s rules for remotely operated UAVs .
