| | It's not about how the machine works. It's about how humans are wired.
What's remarkable about the battle bots is that humans bond with them even though their designers have made no attempt to load them with emotional cues. Troops use cheap little scouts like the MARCbot as a point man on reconnaissance. It is basically a remote-controlled toy truck made military tough and embellished with a long neck to which has been added a camera. Its little head peers around doors and into windows, or it cranes up to examine suspicious packages. Soldiers refer to such bots as "like a 10th man," and "like an extra set of eyes," Brooks reports. They also refer to them as "Johnny Five," the intelligent robot of our celluloid dreams in the "Short Circuit" films.
It's common for a soldier to cut out a magazine picture of a woman, tape it to the antenna and name the bot something like "Cheryl," says Paul Varian, a former Army chief warrant officer who has served three tours in Iraq with the Robotic Systems Joint Project Office. "There's an awful lot of picture-taking," he says. One guy who married just before deployment wanted his wife to see the gal who was his constant companion. It was a PackBot. "One Guard unit got so attached to a development model that we gave it to them. It was pretty beat up. They put it in a place of honor in their museum."
"When we first got there, our robot, his name was Frankenstein" says Sgt. Orlando Nieves, an EOD from Brooklyn. "He'd been in a couple of explosions and he was made of pieces and parts from other robots." Not only did the troops promote him to private first class, they awarded him an EOD badge -- a coveted honor. "It was a big deal. He was part of our team, one of us. He did feel like family."
"I've been a proponent for a long time of painting a mouth and eyes on the Global Hawk," the Learjet-size surveillance bot, says retired Col. Tom Ehrhard, a former chief of the Air Force's "Skunk Works" -- its strategy, concepts and doctrine division.
"It looks like a blind mole. Give it some character. Make it easier for humans to deal with -- more animate. Humans are social animals. Make that other thing part of your family, your social structure. Try to animate and make either fearsome or lovable your implements of war."
Brooks wonders if engineers should actively try to create battle bots that adapt to particular individuals, like a dog. "I'm from Australia," he says, "and Australian sheepdogs -- you and the dog build up a strong working relationship. One could imagine a tactical situation where you're a troop of guys who train together, know each other quite intimately, recognize little hand gestures. One can imagine a deeper sense of communication with a particular bot that is working with those people for a long time, seeing their image, the way their hats are cocked, identifying them based on their gait. One could imagine doing the research to get to that. It's not out of this world."
Medals for Machines
If a robot performs magnificently in battle, should its operator get a medal? Even if that human is hundreds, if not thousands, of miles from the action? The question goes to the heart of a novel issue: Where does the bot end and the human begin?
Last month, the Army announced that it would allow unmanned air vehicle (UAV) operators to earn the Distinguished Flying Cross, the high military honor awarded for heroism or extraordinary achievement while participating in flight.
When Greg Harbin was piloting one of the first Predators over Bosnia from his desk in Hungary, he wasn't actively trying to become the first UAV operator in history to be awarded a medal. He was trying to avoid becoming the first UAV pilot to incinerate a schoolyard full of children.
The then-32-year-old Air Force captain's bot was "dead square right over the city" of Mostar, looking for snipers, when its engine conked out. As it spiraled down, still carrying 2,000 gallons of fuel, Harbin could see on his screen, through the cross hairs of the nose camera, that "it was dead-centered on that school. If I'd allowed that thing to hit into that school, could you imagine?" he recalls. "I would be the first guy in the history of the world to kill somebody with an unmanned aircraft."
Using the kind of fancy flying he'd learned as a fighter pilot, and only the 15 minutes' worth of battery power he had left, he miraculously pulled the bot out of its spiral and found an airstrip run by the French. To make sure the barely-under-control bot didn't hit all their transport planes, he intentionally crash-landed it on their runway. "The French were pretty funny on the radio. They didn't know what it was. They videotaped the whole thing."
But that's not the significant part.
As he was struggling to bring the bot down without an engine, he could see "the ground coming real fast." He dropped the landing gear, flared the wings, pushed the stick forward and then started fumbling around at the bottom of his desk chair.
He had bonded so tightly with the machine hundreds of miles away that he was searching for the lever that would allow him to eject.
It's About the Humans
"EODs are very brave people," Varian says. "They don't put on any sense of weakness." That's why when they get "back from a really rough mission -- the bot got blown up and it could have been them -- we have an area for them to come in, get out of the heat. The refrigerator is stocked with cold drinks and snacks. We've got a satellite phone in the shop. If they haven't talked to the wife, mom and dad, the girlfriend, we give them a phone call back to the States.
"When we talk a system, we're talking the operator as well. We take these guys out, show them where to get a good shower, take them over to the PX, the chow hall. Wind them down while the techs go ahead and try to make a repair on that particular robot. We preach to everybody, you have to look at the system. Not just the machine, but the human."
Nonetheless, Ehrhard worries that a bot "completely changes the human role" in warfare. "That is not lost on these people," he says. "Part of what a society has to do to sacrifice lives is make it heroic. Do you see the dilemma? It's a fundamental dilemma. Look at what we do for the military. Give them uniforms, great burials, medals. I'm retired and people still call me colonel. It's all out of respect for what you have done. How do robots change that?"
Glimpsing the Future
It's not just muddy-boot soldiers facing these questions. It's all of us.
No less an authority than Bill Gates, in a recent Scientific American article titled "A Robot in Every Home," announces that the next big technological wave sweeping the world is robots. He compares their rise to the PC revolution he helped lead.
The bot world "reminds me so much of that time when Paul Allen and I looked at the convergence of new technologies and dreamed of the day when a computer would be on every desk and in every home," he writes. "Robotic devices will become a nearly ubiquitous part of our day-to-day lives." He describes a world "when the PC will get up off the desktop and allow us to see, hear, touch and manipulate objects in places where we are not physically present" -- from planting crops, to allowing doctors to treat distant patients, to providing care for children and the elderly.
That world is arriving fast. The 2 million personal bots in use around the world in 2004 are expected to grow to 7 million next year. The South Korean Ministry of Information and Communication hopes to put a bot in every home there within six years.
Joseph W. Dyer, the retired three-star admiral who heads iRobot's government and industrial division, says, "The androids in the movie 'I, Robot,' who are projected to exist in 2030? We think that timeline is about right."
Most bots won't look semi-human, like C-3PO. Nonetheless, Gates says, "they could have just as profound an impact on the way we work, communicate, learn and entertain ourselves as the PC has had over the past 30 years."
Perhaps those days have already arrived.
Right now Avis is airing a 30-second spot that features a young man in a necktie having a conversation with the navigation bot in his rental car.
"Traffic ahead," the female voice says to him.
"Incredible!" he replies. "You found a golf course near the conference -- awesome Chinese. Now you find me a way around traffic."
He shakes his head and lifts his thumbs off the wheel in a gesture of emotional helplessness.
"I love you," he says with feeling.
The music swells:
Turn around / Every now and then I get a little bit lonely / And you're never coming 'round.
Fall hard for a bot at Avis.
