Since you unwrapped the drone Santa聽gave you for Christmas you鈥檝e:聽

  • Thoroughly annoyed your neighbors
  • Caused serious damage by flying it into your TV, your child, or your dog.聽
  • Gotten at least one threatening letter from the FAA.聽
  • All of the above.

Now it鈥檚 high time you put that drone to work doing something useful鈥攍ike, say, fetching cold ones.聽

A few weeks ago showing a drone carrying a beer featured on a few time-wasting websites. But watch and you鈥檒l see that the mechanics of 鈥渢he get鈥 are all done off screen鈥攆or all we know, there鈥檚 someone standing in the next room, carefully hooking the beer to the drone.

But sometimes鈥攍ike when you鈥檙e fly fishing and your beers are all the way back at the campsite鈥攜ou need the drone to do all the heavy lifting, and we wondered, is that possible? 聽聽

It is鈥攂ut you鈥檙e going to need a little creative problem solving to make it happen. Here鈥檚 your step-by-step guide to turning your quadcopter into a personal beer delivery service. (Note: You should definitely do this with aluminum cans, not glass bottles, okay guys?)

Step One: Figure Out Whether Your Drone Can Hang聽

A 12-ounce can of beer isn鈥檛 terribly heavy, but it鈥檚 hefty enough that your drone will need a solid motor and decent stabilization to get the beer safely into your loving arms. 鈥淎 drone that cost $800 or more is going to be strong enough and have some pretty sophisticated stabilization technology,鈥 says Tobin Fisher, the CEO and co-founder of , a drone company specializing in safe, portable drones that capture exceptional action video. Ideally, your drone should have gimbal axis stabilization, which Fisher says is the current gold standard (the DJI Phantom 3 has this type of stabilization system, as do many of the other high-end fliers). 鈥淕imbal stabilization is best and digital stabilization is second best. No stabilization is painful,鈥 says Fisher鈥攎eaning your video stream as you tried to pick up the beer would be nauseatingly shaky.聽

Step Two: Figure Out Your 鈥淐atch Mechanism鈥

Unfortunately, robotic gripping arms haven鈥檛 evolved as fast as other drone technologies, says Jackie Wu, the founder of , a drone startup. So, at least for right now, using a robotic claw to pick up your frosty tall boy isn鈥檛 going to happen.聽

Instead, the easiest way to pick up that can is going to be with a magnet. But aluminum cans aren鈥檛 magnetized, so you鈥檒l need to attach a magnet to the top of each can. 鈥淚f you glued a magnet to the top of each can that would probably be easiest,鈥 says Fisher.聽

The good news is you only need a tiny magnet to do the job. Michael Paul of K&J Magnetics says you鈥檒l only need a magnet with .75 pounds of pull force to hold onto a 12-ounce can, though for extra security you might want to choose one with slightly more. The company sells a pencil eraser-sized that has 2.30 lbs. of pull force, which would be more than enough. At 34 cents, it鈥檚 a small price to pay for the space-age thrill of having your beer delivered by robot.

After gluing a magnet to your beer can, tie a sturdy bit of string to your drone and affix another magnet to the end of the string. Tie it as close to the center as you can so it doesn鈥檛 throw your drone off balance.

Step Three: Set Your Beer Location and Set Up Your Cooler

Set your cooler down where you want to store your beer and then pull up your drone鈥檚 GPS map. Drop a pin exactly where the cooler is. All you have to do is make sure your drone can fly itself to the vicinity of the cooler so that you can guide it to the beer remotely. 鈥淭he GPS location will be accurate to plus or minus a meter or so,鈥 says Fisher. Glue one more small magnet to the top of your cooler; this will allow you to open your cooler when the time comes. Once your GPS coordinates are set, march off into the woods with your drone in tow.聽

Step Four: Fetch, Drone, Fetch!

When you start feeling thirsty, point your drone towards the GPS point you set and send it on its way. After that, you can stream the images your drone is sending to your phone to let you gently lower the craft down to your cooler (more on that in a bit).

Step Five: Open The Cooler聽

Fly聽down, attach your drone to the magnet on the cooler, and then fly up sharply. The drone will pull open the lid and then disconnect when it can鈥檛 lift the cooler off the ground. Your ice cold beers will now be in view.聽

Step Six: Pick up Your Beers

Channeling your inner kid-at-an-arcade, use your phone screen to lower the drone, attach the two magnets, pick up the beer, and fly it back to you.聽

Step Seven: Serve Yourself First

Unless you own a massive drone, you鈥檒l have to move the beers one at a time, and carrying a heavy object will seriously limit your battery life. Fisher points out that most consumer drones can fly up to 20 miles an hour, so it won鈥檛 take long to make each trip. Still, most drones also have a battery life that supports about 20 minutes of flying time, and that鈥檚 without a beer in tow. So if you鈥檙e hanging with a group, it鈥檚 probably best to make the event BYOD鈥攖hat鈥檚 bring your own drone.聽
