A zipping comes across the sky.
A man named Neil Parfitt is standing in a field on a cattle ranch outside Warwick, Australia. A white vehicle appears above the trees, a tiny plane a bit bigger than a seagull. It glides towards Parfitt, pitches upwards to a vertical position, and hovers near him, a couple hundred feet in the air. From its belly, a package comes tumbling downward, connected by a thin line to the vehicle itself. Right before the delivery hits the ground, it slows, hitting the earth with a tap. The delivery slows, almost imperceptibly, just before it hits the ground, hardly kicking up any dust. A small rectangular module on the end of the line detaches the payload, and ascends back up the vehicle, locking into place beneath the nose. As the wing returns to flying posture and zips back to its launch point half a mile away, Parfitt walks over to the package, opens it up, and extracts some treats for his dogs.
The Australian test flight and 30 others like it conducted in mid-August are the culmination of the first phase of Project Wing, a secret drone program that’s been running for two years at Google X, the company’s whoa-inducing, long-range research lab.
Though a couple of rumors have escaped the Googleplex—because of course Google must have a drone-delivery program—Project Wing’s official existence and substance were revealed today. I’ve spent the past week talking to Googlers who worked on the project, reviewing video of the flights, and interviewing other people convinced delivery by drone will work.
Taken with the company’s other robotics investments, Google’s corporate posture has become even more ambitious. Google doesn’t just want to organize all the world’s information. Google wants to organize all the world.
During this initial phase of development, Google landed on an unusual design called a tail sitter, a hybrid of a plane and a helicopter that takes off vertically, then rotates to a horizontal position for flying around. For delivery, it hovers and winches packages down to the ground. At the end of the tether, there’s a little bundle of electronics they call the “egg,” which detects that the package has hit the ground, detaches from the delivery, and is pulled back up into the body of the vehicle.
That Parfitt would be the man on the receiving end of the tests was mostly happenstance. Google’s partner in the country, Phil Swinsburg of Unmanned Systems Australia, convinced him to take part in the demonstration deliveries launched from a nearby farm. (Australia’s “remotely piloted aircraft” policies are more permissive than those in the United States.)
Standing with Parfitt as he received dog treats from a flying robot was Nick Roy, the MIT roboticist who took a two-year sabbatical to lead Project Wing. In all the testing, Roy had never seen one of his drones deliver a package. He was always at the takeoff point, watching debugging information scroll up the screen, and anxiously waiting to see what would happen. “Sergey [Brin] has been bugging me, asking, ‘What is it like? Is it actually a nice experience to get this?’ and I’m like, ‘Dude, I don’t know. I’m looking at the screen,’” Roy told me.
So, this time, as he prepared to end his tour of duty at Google X and return to MIT, he watches as the Wing swoops and delivers. Recalling that moment, he struggles not to sound too rapturous or lose his cool technical objectivity. “Once the package is down and the egg is back up, the vehicle gains altitude, and does this beautiful arc, and it’s off again,” he said. “That was delightful.”
The parting between Roy and Google X seems amicable. When Astro Teller, director of the lab, described it to me in an interview in Mountain View, he literally patted Roy on the knee. “Nick was super ultra-clear with us from day one, despite lots of pressure from me,”—Teller pat Roy on the knee—“that he was going to leave after two years.” But the timeline was good, Teller maintained, because it gave the project shape and a direction.
In the two years, Roy’s goal was simple: figure out if the idea of drone delivery made sense to work on. Should Google pursue creating a real, reliable service? Was it possible? Could a self-flying vehicle be built and programmed so that it could take off and land anywhere, go really fast, and accurately drop a package from the air?
The answer, Roy and Teller say, is yes. They have not built a reliable system Google users can order from yet, but they believe the challenges are surmountable. Now, Google will begin growing the program in an ultimate push to create a service that will deliver things people want quickly via small, fast “self-flying vehicles,” as they like to call them.
Teller has found a replacement for Roy in Dave Vos, a 20-year veteran of automating flying machines, who sold his drone software company, Athena Technologies, to Rockwell in 2008. Where Roy got to play what-if and why-not, Vos must transform the Wing into a service that real people might use.
“What excited us from the beginning was that if the right thing could find anybody just in the moment that they need it, the world might be radically better place,” Teller said.
