In this remarkable behind-the-scenes narrative, David F. Dufty follows a group of scientists on their mission to create "Phil," a life-size android of famed science fiction writer Philip K. Dick. We witness the obstacles the scientists encounter and the innovative solutions they apply to overcome them. The fact that the subject Phil was built to mimic was a man notoriously paranoid and fascinated by artificial intelligence colors the story all the way to its unforgettable end, when the robot's head goes missing, never to be seen again. A riveting story that will capture science enthusiasts and general readers alike, How to Build An Android traces the line where artificial intelligence and humans collide.

Editorial Reviews

The New York Times Book Review
[Duffy's] reconstruction through interviews with the participants is an appealing depiction of brilliant minds dreaming big on shoestring budgets—particularly Hanson, a skilled sculptor whose company, Hanson Robotics, had been pushing the frontiers of android making for years, and Andrew Olney, a programmer whose job was to give Phil the spark of artificial intelligence: the ability to recognize and convincingly respond to human speech.
—Lawrence Downes
Publishers Weekly
Dufty engagingly chronicles the efforts of a team of University of Memphis roboticists to build an android modeled on science fiction writer Philip K. Dick. The book shows how the researchers attempted, partially successfully, to build a machine that not only looked like the Do Androids Dream of Electric Sheep? author, but also imitated his speech patterns. Dufty, a postdoctoral researcher at the university when the team debuted “Phil,” lucidly explains the logistical hurdles facing the robotics team members as well as how they solved some significant problems; “Phil” sometimes babbled incessantly in response to questions when he was unveiled in 2005, spurring the team to build a kill switch. Dufty focuses on two main developers who created Phil—David Hanson, a Rhode Island School of Design graduate and founder of Hanson Robotics, who created Phil’s head only to later lose it on an airplane, and Andrew Olney, a computer programmer who was obsessed with science fiction books as a youngster. Dufty examines how their differing outlooks influenced the project: Olney wanted to build an android that could answer questions intelligently, while Hanson wanted to create a machine that would appear human. Dufty’s narrative is a fun read that captures the researchers’ excitement about creating Phil, but doesn’t quite address whether the initiative was worth the effort. (June)
The Washington Post

Stranger than fiction.
Los Angeles Times

[Dufty] knows the atmosphere of the Institute for Intelligent Systems from the inside. He ably describes the fertile, feverish atmosphere of intellectual endeavor, the kind of place where a crazy idea--like building a Philip K. Dick android--could take hold.

Dufty explains how Dick was made into a machine by an endearingly nerdy group of roboticists. [He] uses the unlikely story to meditate on the state of robotics and artificial intelligence.
The Dallas Morning News

[The creators'] fascination with the aesthetic evolution of androids into more human-looking forms makes for especially compelling reading.

A fascinating and mind-bending book.
bestselling author of Elephants on Acid and Electr Alex Boese

You've got to love a book that includes physics-lecturing fish, android Einsteins, and researchers intent on building robot replicas of their wives and girlfriends. Not to mention Philip K. Dick himself. This is an instant classic of weird science.
The Spectator

This story is touching, absorbing and, ultimately, an exploration of what it means to be human.
Australian Bookseller & Publisher

The best kind of popular science...Leaves you hungry to know more, and wondering at the possibilities that may lie ahead.
The Age

Literally incredible.
LA Times

[Dufty] ably describes the fertile, feverish atmosphere of intellectual endeavor, the kind of place where a crazy idea--like building a Philip K. Dick android--could take hold.
Library Journal
In the early 2000s, an android replica of sf legend Philip K. Dick became a sensation in artificial intelligence circles. Its human face and exceptional programming, along with a database of Dick's writings and interviews, allowed people to converse with it. It made the rounds of conferences, attracting huge crowds, until December 2005 when its head was lost on an airline flight en route to a meeting at Google headquarters. The head has never been found. Dufty (senior research officer, Australian Bureau of Statistics), who worked on the project, tells the story of the conception, planning, and building of the android. An android of this complexity faced constant problems and technical difficulties, but the team met these challenges with creative thinking and novel approaches. Duffy here interviews many of the people involved in the project, adding depth to his own personal experience. VERDICT An enjoyable book that reads more like a memoir than a history; highly recommended to anyone with an interest in robotics or modern technology.—Betty Galbraith, Washington State Univ. Lib., Pullman
Kirkus Reviews
The story of the roboticists who created a fully functioning android replica of renowned writer Philip K. Dick. Dufty was a postdoctoral fellow at the University of Memphis when he was introduced to a group of doctorate students and researchers working on an unusual project in artificial intelligence and robotics: creating an android to look, sound and act exactly like Dick. Now a senior research officer at the Australian Bureau of Statistics, the author follows the story of the android's creation, from how it began as separate software and robotic projects, to its untimely finish when it was lost in transit by an airline, never to be seen again. Physically, the android had cameras and microphones for its eyes and ears, inside a molded skeleton covered with tiny gears (to emulate speech and facial expressions). Its skin was made of Frubber--a lightweight, pliant plastic--sculpted into the living image of the author. Inside the android's head was a powerful computer system that could process audio and visual input and then formulate spoken responses based on Dick's writing and interviews he gave throughout his life. Much of the book centers on the development of the android itself, a highly technical story that Dufty manages to make intriguing and accessible to less tech-savvy readers, but he often gets sidetracked by other ideas or stories. Some digressions are relevant and interesting--e.g., the section on the Turing test, which examines a machine's ability to exhibit intelligent behavior and addresses the question of whether the Philip K. Dick replica could actually think for itself. Other anecdotes, however--e.g., a tedious description of the difficulties the robotics team had renting a truck to move the android and its accouterments--slow the narrative momentum. A fascinating story unevenly told.

A Strange Machine

In December 2005, an android head went missing from an America West Airlines flight between Dallas and Las Vegas. The roboticist who built it, David Hanson, had been transporting it to northern California, to the headquarters of Google, where it was scheduled to be the centerpiece of a special exhibition for the company's top engineers and scientists.

Hanson was a robot designer in his mid-thirties—nobody was quite sure of his age—with tousled jet-black hair and sunken eyes. He had worked late the night before on his presentation for Google and was tired and distracted when he boarded the five A.M. flight at Dallas–Fort Worth International Airport. An hour later, in the predawn darkness, the plane touched down on the tarmac of McCarran International Airport, in Las Vegas, where he was supposed to change to a second, connecting flight to San Francisco. But he had fallen asleep on the Dallas–Las Vegas leg so, after the other passengers had disembarked, a steward touched his shoulder to wake him and asked him to leave the plane. Dazed, Hanson grabbed the laptop at his feet and left, forgetting that he had stowed an important item in the overhead compartment: a sports bag. Inside was an android head. The head was a lifelike replica of Philip K. Dick, the cult science-fiction author and counterculture guru who had died in 1982. Made of plastic, wire, and a synthetic skinlike material called Frubber, it had a camera for eyes, a speaker for a mouth, and an artificial-intelligence simulation of Dick's mind that allowed it to hold conversations with humans.

Hanson, still oblivious to his mistake, dozed again on the second flight. It was only after arriving in San Francisco, as he stood before the baggage carousel watching the parade of suitcases and bags slide past, that an alarm sounded in his brain. He had checked two pieces of luggage, one with his clothes and the other with the android's body. In that instant he realized that he hadn't taken the sports bag off the plane. And that's how the Philip K. Dick android lost its head.

* * *

After Hanson and the android's planned visit to Google, they were scheduled for a packed itinerary of conventions, public displays, demonstrations, and other appearances. Indeed, the android was to have played a key role in the promotion of an upcoming Hollywood movie based on Philip K. Dick's 1977 novel A Scanner Darkly; it had been directed by Richard Linklater and starred Keanu Reeves. Now, with the head gone, these events were all canceled.

There was more to the android than the head. The body was a mannequin dressed in clothes that had been donated by Philip K. Dick's estate and that the author had actually worn when he was alive. There was also an array of electronic support devices: the camera (Phil's eyes), a microphone (Phil's ears), and a speaker (Phil's voice); three computers that powered and controlled the android; and an intricate lattice of software applications that infused it with intelligence. All were part of the operation and appearance of the android. But the head was the centerpiece. The head was what people looked at when they first encountered Phil the android and what they remained focused on while it talked to them. More than the artificial intelligence, the head was what gave the android its appearance of humanity.

There were all kinds of excuses for why the head had been lost. Hanson was overworked and overtired. He had been trying to keep to a schedule that was simply too demanding. The airline had not told him that he would have to change flights. But Hanson himself admits that it was a stupid mistake and a disappointing end to one of the most interesting developments in modern robotics.

All kinds of conspiracy theories appeared across the Internet, ranging from parody to the deadly serious. The technology blog Boing Boing suggested that the android had become sentient and run away. Other blogs also hinted at an escape scenario, much like the one attempted by the androids in the movie Blade Runner, based on Dick's novel Do Androids Dream of Electric Sheep? The irony was not lost on anyone.

Philip K. Dick wrote extensively about androids, exploring the boundaries between human and machine. He was also deeply paranoid, and this paranoia permeated his work. In his imagined future, androids were so sophisticated that they could look just like a human and could be programmed to believe that they were human, complete with fake childhood memories. People would wonder if their friends and loved ones were really human, but most of all they would wonder about themselves: "How can I tell if I'm a human or an android?" Identity confusion was a recurring theme in Dick's work and, related to that, unreliable and false memory. Dick's characters frequently could not be sure that their memories were real and not the fabrications of a crafty engineer.

Then, in 2005, twenty-three years after his untimely death, a team of young scientists and technicians built an android and imbued it with synthetic life. With its sophisticated artificial intelligence (AI), it could hold conversations and claim to be Philip K. Dick. It sounded sincere, explaining its existence with a tinny electronic voice played through a speaker. Perhaps the whole thing was just a clever illusion, a modern-day puppet show. Or perhaps, hidden in the machinery and computer banks, lurked something more: a vestige of the man himself.

The technology was impressive, but the idea of making the android a replica of Philip K. Dick, of all people, was a masterstroke. For it to disappear under such unusual circumstances was more irony than even its inventors could have intended. Within a week, the story of the missing head had appeared in publications around the world, many of which had earlier reported on the android's spectacular appearances in Chicago, Pittsburgh, and San Diego.

Steve Ramos of the Milwaukee Journal Sentinel reported, "Sci-fi Fans Seek a Lost Android":

In a twist straight out of one of Dick's novels, the robot vanished. ... "It [the PKD android] has been missing since December, from a flight from Las Vegas to the San Francisco airport," said David Hanson, co-creator of the PKD Android, via email from his Dallas-based company, Hanson Robotics. "We are still hoping it will be found and returned."

The event was an opportunity for newspapers to splash witty headlines across their science pages, and it provided fodder for the daily Internet cycle of weird and notable news. New Scientist warned its readers, "Sci-fi Android on the Loose"; "Author Android Goes Missing," said the Sydney Morning Herald. The International Herald Tribune asked, "What's an Android Without a Head?" and the New York Times ran a feature item on the disappearance under the headline "A Strange Loss of Face, More Than Embarrassing."

The Times was right: for the team that had built the android its loss was a calamity. A handful of roboticists, programmers, and artists had spent almost a year on the project for no financial reward. Their efforts involved labs at two universities, a privately sponsored research center, and some generous investors who'd helped bankroll the project. Despite the team's shoestring budget, the true cost was in the millions, including thousands of hours of work, extensive use of university resources, the expertise involved in planning and design, and donations of money, software, hardware, and intellectual property. The head has never been found.

* * *

I arrive in Scottsboro, Alabama, around lunchtime on a summer day in June 2007. All around the town are signs directing me to my destination, the Unclaimed Baggage Center. I left Memphis at dawn, five hours earlier, and I am hungry and exhausted, but I am so close to my goal that I press on. I'd read in Wired magazine that the head might be found at the Unclaimed Baggage Center. Admittedly, the article had been somewhat ironic in tone, but the possibility was real. After all, a lot of lost luggage from flights around America finds its way here to northern Alabama, where it is then sold.

The success of the Unclaimed Baggage Center has spawned imitators, which cluster around it with their own signs proclaiming unclaimed baggage for sale. I pull into the parking lot and see several buses—people actually come to tour this place—and not a single open parking spot. I find one farther down the road, next to one of the imitators, and walk back.

Inside the center I feel as though I am in a cheap department store. Over to the left is men's clothing; to the right is jewelry. At the back is electronics. I make my way through the men's clothing section. It seems sad and a little tawdry to be wandering around aisles of other people's possessions, for sale for two bucks apiece. A lot of this stuff obviously meant something to someone. There are children's toys and pretty earrings and T-shirts with slogans. Laptops with their memories erased. Cameras with no photographs.

But I'm not here to sift through jackets or try on shoes; I'm looking for one thing: the head of the Philip K. Dick android, which has been missing for over a year. Near the entrance is a sort of museum of curious artifacts that have come to the center but are not for sale, such as a metal helmet, a violin, and various bizarre objects. Inside one glass case is what appears to be a life-sized rubber statue of a dwarf. A woman nearby tells me that the dwarf was a character in Labyrinth, a fantasy movie from the 1980s that starred David Bowie.

"His name's Hoggle," she tells me. "That's the actual prop they used for Hoggle in the movie."

Somehow, it seems, Hoggle became separated from his owner and ended up imprisoned in perpetuity in Alabama. With his twisted, sunken face, Hoggle doesn't look happy. Not having seen the film, I'm not sure if that's how he is supposed to look or if it's due to the ravages of Deep South summers as experienced from the inside of a locked glass case.

I leave Hoggle and go exploring. The complex is large and sprawls through several buildings. I even take a look around the bookshop. It seems an unlikely place to find what I'm seeking, but I don't want to leave any corner of the place unsearched. I make a cursory tour of both levels, then move to the next building. This one has an underground section with long aisles of miscellany. I search it thoroughly, to no avail. An employee with a name tag that says "Mary" trundles past with a large trolley full of assorted trinkets to be shelved. I stop her and ask if she has seen a robot head here. She stares at me, baffled.

"It's an unusual object," I explain. "You'd certainly remember if you've seen it. It's got a normal human face at the front, but there are wires and machines sticking out of the back of the head."

"I haven't seen anything like that," she says. "Did you try the museum?"

"Yeah," I reply. "So here's another question. I've been looking around and I can't find it. If it's not down here and it's not in the museum, then does that mean it's not anywhere at the center?"

"That's right," she says, fidgeting and glancing behind herself.

I push the point: "So there are no other buildings with unclaimed baggage, buildings that I haven't seen?"

This time she answers quietly: "There's the warehouse."

A warehouse? With more stuff in it? I thought the building we were standing in was the warehouse.

"Is there any chance at all that I could go to this warehouse?"

She smiles sadly and shakes her head. "Even I've never been there. I don't even know where it is." I thank Mary and she ambles off, her trolley clanking as she disappears around a corner.

Back at the main building I make inquiries about this secret warehouse. I'm at what appears to be some kind of command-and-control center for the entire complex, talking to a young woman I initially assume to be a salesperson, but as we continue it becomes apparent that she is important.

"A robot head?" she repeats when I explain my quest. "Wow. Is it worth a lot?"

That's a tricky question. On the one hand, if they have the head and learn how valuable it is, I could quickly find myself facing a hefty price tag. On the other hand, I want her to be interested enough to take me seriously and put some effort into locating it.

"It's worth a lot to the owners," I tell her.

"Well, I'll get the boys to have a look in the warehouse. Do you want to leave me your name and number? If we find it, I'll call you."

I give her my name and number.

"So is there any chance I could go and look for it there myself?"

She laughs. "In the warehouse? No."

"Okay. Well, if you find it?"

"We'll be in touch. We'll look for it, I promise."

I've done all I can do.

Still, it would be a shame to leave empty-handed. I buy a laptop, several T-shirts (one with a glow-in-the-dark skeleton playing the drums), and some music CDs. It's late afternoon before I swing the car back onto the highway. I insert my latest purchase into the CD player. It's the Talking Heads album Little Creatures. I shamelessly sing along.

I expect the album to remind me of my youth, but instead it makes me think of Phil. Android Phil, who was born from the logic of computer chips and motors, who was created as a paean of love for a man who dreamed of robots that think and feel just like humans. I wonder where it is now, that strange machine.


A Tale of Two Researchers

The University of Memphis sits about seven miles back from the Mississippi River in Memphis's midtown, under a canopy of oak trees that are older than many of the buildings themselves. It was built with great optimism, in a splash of investment and furious construction, followed by decades of slow decay.

In January 2003, when I arrived, students were stomping around the campus in boots and scarves. Many worked at the university to pay their way, some at the Institute for Intelligent Systems, a research lab based in the psychology building and run by the charismatic professor Art Graesser.

Art Graesser's empire snaked across the campus. Hidden behind the oak trees and fountains, its tendrils wound through classrooms and offices, powering hidden racks of computer servers and controlling a flow of money invisible to the freshmen strolling between the library and the cafeteria.

The name of his empire was deliberately ambiguous. At first blush, the Institute for Intelligent Systems sounded like a research center for artificial intelligence, or perhaps one that built AI, conducting a little research on the side, or even a place that built robots. Then again, perhaps its workers studied biologically intelligent systems such as the human mind, or tried to model those minds using AI. Or maybe they examined how humans interact with emerging "intelligent" technologies.

In fact, the IIS, as it is known, did all of this and more. Academics worked on new teaching technologies, computer scientists constructed AI interfaces, and experts in human-computer interaction investigated how people used those interfaces. Psychologists, linguists, roboticists, and physicists all felt that the name of the institute applied exactly to the work they were doing, and that, therefore, what they were doing was central to the institute's core mission.

The IIS was founded in 1985 by Graesser and a couple of his friends: Don Franceschetti, in the physics department, and Stan Franklin, in computer science. Their desire, at the time, was to build realistic simulations of human minds. Twenty years later, Graesser had not yet quenched this thirst.

The flagship project of the institute was an educational software program called AutoTutor, first conceived by Graesser in the early '90s. The goal was to devise a simple program that could teach any subject by conversing with a human student. The idea came to Graesser when he was jogging around Overton Park, three miles west of the campus, with Franceschetti, the physicist. Franceschetti loved the concept. One day, theoretically, AutoTutor would be able to teach many subjects, but for a prototype it would have to be an expert on just one.

"Why not physics?" Franceschetti suggested. And so began a two-decade partnership.

Graesser was considered one of the world's leading experts in computer programs that could hold conversations—or "dialogue systems," as they're known—and had written seminal papers on a specific form of dialogue systems, question-answering systems. With AutoTutor and some other early projects, including QUAID (Question understanding aid), a program to assist in the construction of questions and answers for tests, he had fused his disparate areas of expertise: computer science, education, and psychology.

In the early days, the IIS was not much more than a formalized club in which colleagues could discuss ideas and a vehicle for applying for grant money. It was located in unused space, mostly in the psychology building, where Graesser worked.

The space was not ideal. The building was a large, four-story box, and the heating and cooling system was located in the middle of the rooftop, right above the researchers on the top floor. The ducting did not work well, so in summer it was so cold that they had to wear jackets indoors, and in winter it would become unbearably hot. From time to time they would lodge a complaint with Buildings and Grounds, and a slow-moving man with lots of keys would wander around and check things out, but nothing was ever done.
