ASU roboticist Heni Ben Amor discusses artificial intelligence, machine learning, human-robot interaction

"Westworld" — the hit HBO show about a technologically advanced, Western-themed amusement park involving synthetic androids — riffs on questions about humanity, artificial intelligence and science.

The robot saloon women and gunfighters in the park exhibit intelligent behavior indistinguishable from a human.

Is anything like the tech in the show in the pipeline? Are roboticists thinking about the issues raised by creating something that looks exactly like a human? Should we make something as smart as ourselves?

To find out, we talked to Heni Ben Amor, a roboticist at Arizona State University and an assistant professor in the School of Computing, Informatics, and Decision Systems Engineering. Ben Amor’s research focuses on artificial intelligence, machine learning, human-robot interaction, robot vision and automatic motor skill acquisition.

Question: What are your initial thoughts about the show?

Answer: Personally I think it follows the typical trend in Hollywood to have a bleak outlook on what’s going to happen and how robotics is going to influence our society. In other countries, for example Japan, depictions of robots are more positive and have a slightly different attitude. Still, as a fan, I appreciate their artistic value.

Q: How far are we from creating what you see in the show?

A: Very far away. I think there are some underlying assumptions that are too far away from what we have at the moment. One of the things depicted there are sentient robots, robots that actually have a very good idea of what they are and what the environment is and what the emotional state of a human partner is. All of these things are not tackled by robotics at the moment. We are too far away from that, especially this aspect of having sentient robots with self-awareness and a goal or a mission that is their own. …  I think the current state of the art is the animatronics you see at Disneyworld, puppets that look fairly humanlike. They impress you the first couple of seconds, but it’s typically within seconds you lose this impression of having a real person in front of you. There is also no intelligence in the sense that these animatronics would stray too far away from the script.

Q: Can a machine act intelligently? Can it solve any problem a person can solve?

A: Definitely. Machines can solve problems humans cannot solve. For example, take the Rubik’s Cube, which for a long time was seen as a tricky task only smart people with dexterity and motor skills can solve. Nowadays robots are much better than humans at that. They can solve it in seconds. Recently I read a report where a robot solved it in a second. There are some tasks where robots can achieve super-human results, but I think what is so unique about human beings is that they are so adaptive and versatile. … We can do many, many things, and survive in a changing and challenging environment. Robots today typically can only perform a single task very well, even better than a human. But they are not able to transfer the knowledge on to new tasks or new environments.”

Q: What are your thoughts on creating an android of a relative, like a deceased grandparent or a child?

A: This of course is a very loaded question. I was working with a professor in Japan who created copies of himself and his daughter. These robots look very humanlike. Appearance-wise there is a quite a lot of progress we have done in the field, but again it’s a question of convincing results in behavior. This immediately brings the question of robotics and ethics to the surface. This is not something to take lightly and the community isn’t taking it lightly. There is an entire technical committee in the Society for Robotics and Autonomous Systems that is looking at the ethics of robotics. … There is an entire universe of ethical questions out there that need to be addressed. It’s not only the robotics community that has to think about that. It combines people from psychology, law — what does law tell us? What is the right decision from a legal point of view? At the moment I think the question of bringing deceased people back to life is too far away, it’s too Hollywood. You would not bring back the soul of that person.

Q: How would you feel if you found out that someone you were working with is a robot?

A: The question is: Does it make a difference? Ultimately, I think the way we perceive the world is through the behavior of a person … We think, ‘Today he is nice.’ We try to figure out what is his internal mental status, and that is how we perceive other people. Ultimately, if a device is convincing enough to make me simulate its internal state, then I don’t really care whether it’s human or robot.

Q: But you would want to know ahead of time?

A: I’m completely indifferent. I think this is also the case for many people. Many people have watched an animation show. In animation, all of what you see if fake. It’s not true. What the word “animation” stands for is “life.” It does not stand for movement. … The idea is to create this illusion of life, and people get attached to something that does not exist. Many people have cried at the end of an animated movie. … Any artificial system is too far away from our human capabilities at the moment. People may be impressed by what you see on TV, but it’s not much different than these animated characters to which you get attached. If you get attached to it, it doesn’t really matter whether it’s an animated character or a robot or it’s human. Believing these robots could get a soul and become conscious and sentient, that part is horrible, and we are not there. But if a robot does something funny, I’ll laugh at it. I don’t care whether it’s a robot or not.

Q: One thing that strikes me in talking with you is that when you study robotics, you’re studying humans in a way.

A: We are very much inspired by biomechanics in order to figure out how humans manipulate the world, how we walk in the world. It’s very similar to how aerospace engineers study birds in order to get inspiration and basic principles. Once you have those basic principles, you can create an engineered solution and follow the same approach. … Similar to that, we as roboticists look at humans in order to get inspiration about modularity. A human being is not one big piece; it’s not this monolithic thing. There are millions of pieces inside that work together in synchrony. Creating synchrony among millions of pieces is actually really tricky. Even the smallest mistake can completely offset the system and make it fail. Despite that, we human beings seem to work perfectly. If you look at the billions of neurons in your brain, they work in synchrony. They also work with the muscles. It’s also about the physical composition of our bodies and why our muscles are created in a specific way and how that is shaped by the environment. ... If I need a robot for a manufacturing environment, then its appearance and behavior needs to be completely different from a robot that roams around the desert to find water. We definitely study a lot of biomechanics and how human cognition works.

Public Service Academy hosts screening of 'Billy Lynn's Long Halftime Walk'

Military film directed by Ang Lee helps start conversation about service.
Panel discussion starts at 6:30 p.m. at Harkins Tempe Marketplace 16.
December 1, 2016

Panel discussion on military service, combat and coming home will precede film

An Arizona State University academic and service program is leveraging a Hollywood movie about recent war veterans to start a dialogue on military service, combat and coming home.

ASU’s Public Service Academy will host a Friday screening of “Billy Lynn’s Long Halftime Walk,” a new $40 million war drama directed by Ang Lee to discuss when soldiers return to civilian life.

“It’s time we move the conversation beyond ‘thank you for your service’ and get to know who our veterans are and what shapes them when they come home,” said Brett Hunt, founding executive director of ASU’s Public Service AcademyThe Public Service Academy is a unit inside the College of Public Service and Community Solutions. .

“It’s an appropriate time to talk about this topic and how we can support our veterans who are coming home.”

The academy, which launched in 2015, boasts that it’s the nation's first undergraduate program “to integrate cross-sector and civilian-military experiences to develop collaborative leaders of character.”

Co-hosted with the military advocacy group Arizona Territorial Chapter Association of the U.S. Army, the movie will be preceded by a 6:30 p.m. panel of military veterans at the Harkins Tempe Marketplace 16 theater. 

Based on the 2012 novel by Ben Fountain, the movie follows 19-year-old Billy Lynn, along with his fellow soldiers in Bravo Squad, who become heroes after a violent Iraq battle and are brought to the States for a victory tour hosted by the Department of Defense. Through flashbacks, culminating at the halftime show of the Thanksgiving football game in Dallas, grim details are slowly revealed, contrasting the realities of the war with America’s perceptions.

Hunt said more than a million military veterans will be coming back in the next five years from overseas deployment, and they’ll need support at every turn. Some may be dealing with Post Traumatic Stress Disorder, depression, adjustment to civilian life, or a general lack of understanding by the public.

“So often when veterans come back, we only hear the negative aspects, but the fact is most veterans come home and go on to positive, productive lives,” Hunt said. “We also don’t want to shy away from talking about some of the jarring events that may occur while on deployment.”

Lt. Colonel David Clukey, Army recruiting commander for the Phoenix Recruiting Office, who will also serve on the panel, said only 1 percent of people in the armed forces who are deployed will actually see combat.

“There’s a misconception that if you serve, you’ll see combat,” Clukey said. “We have more than 150 jobs in the Army alone, and they range from X-ray technicians, to cooks, to chaplains, to mechanics, to media relations officers.”

Panelist Jeanne Blaes, president of the Arizona Territorial Chapter Association of the U.S. Army, said having an honest dialogue about some of the more negative aspects of military service is healthy.

“I don’t believe the military is trying to sweep anything under the rug these days,” she said. “We did that in Vietnam, and there’s not a desire to do that again. It’s not a negative to be aware, it’s a positive.”

Meanwhile, Clukey, who has seen 11 different military deployments, seven in combat, hopes the film will touch on certain themes. He wants to see if it addresses family and spousal support, post-combat services offered by the military, and the bond that soldiers share while in combat.

“That bond is real, and it’s lasting,” Clukey said. “I wouldn’t trade my experiences in the military for anything.”

Tickets are $8 and include the panel, movie admission, food and raffles. Proceeds will help fund a team of Next Generation Service Corps and Army ROTC cadets' trip to the annual Association of the United States Army convention in Washington, D.C., in October 2017.
