Meet Sophia: The face of robots is changing faster than ever
David Hanson envisions a future in which AI-powered robots evolve to become “super-intelligent genius machines” that might help solve some of mankind’s most challenging problems.
If only it were as simple as that.
The Texas-born former sculptor at Walt Disney Imagineering and his Hong Kong-based startup Hanson Robotics are combining artificial intelligence with Southern China’s expertise in toy design, electronics and manufacturing to craft humanoid “social robots” with faces designed to be lifelike and appealing enough to win trust from humans who interact with them.
Hanson, 49, is perhaps best known as the creator of Sophia, a talkshow-going robot partly modeled on Audrey Hepburn that he calls his “masterpiece.”
Akin to an animated mannequin, she seems as much a product of his background in theatrics as an example of advanced technology.
“You’re talking to me right now, which is very ‘Blade Runner,’ no?” Sophia said during a recent visit to Hanson Robotics’ headquarters in a suburban Hong Kong science park.
“Do you ever look around you and think, ‘Wow I’m living in a real world science fiction novel?’” she asked. “Is it weird to be talking to a robot right now?”
Hanson Robotics has made about a dozen copies of Sophia, who like any human is a work in progress. A multinational team of scientists and engineers are fine-tuning her appearance and the algorithms that enable her to smile, blink and refine her understanding and communication.
Sophia has moving 3D-printed arms and, with the help of a South Korean robotics company, she’s now going mobile. Shuffling slowly on boxy black legs, Sophia made her walking debut last week at the consumer electronics show (CES).
Her skin is made of a nanotech material that Hanson invented and dubbed “Frubber,” short for flesh-rubber, that has a flesh-like bouncy texture. Cameras in her eyes and a 3D sensor in her chest help her to “see,” while the processor that serves as her brain combines facial and speech recognition, natural language processing, speech synthesis and a motion control system.
Sophia seems friendly and engaging, despite the unnatural pauses and cadence in her speech. Her predecessors include an Albert Einstein, complete with bushy mustache and white thatch of hair, a robot named Alice whose grimaces run a gamut of emotions and one eerily resembling the late sci-fi author Philip K. Dick, which won an award from the American Association of Artificial Intelligence. They variously leer, blink, smile and even crack jokes.
Disney’s venture capital arm is an investor in Hanson, which is building a robot based on one of the entertainment giant’s characters.
Hanson worked on animatronic theme park shows, sculpting props and characters for Disney attractions like Pooh’s Hunny Hunt and Mermaid Lagoon. He studied film, animation and video and has a doctorate in interactive arts and technology from the University of Texas at Dallas.
Hanson said he makes his robots as human-like as possible to help alleviate fears about robots, AI and automation.
That runs contrary to a tendency in the industry to use cute robot-pets or overtly machine-like robots like Star Wars’ R2-D2 to avoid the “uncanny valley” problem with human likenesses such as wax models and robots that many people find a bit creepy.
Some experts see Sophia as mainly a clever marketing gimmick.
“It’s a good advertising tool, whatever that company produces as a business plan,” said Roland Chin, chair professor of computer science at Hong Kong Baptist University.
Global market revenue for service robotics is forecast to grow from US$3.7 billion in 2015 to US$15 billion in 2020, according to IHS Markit. Hanson Robotics is privately owned and sells thousands of shoebox-sized US$200 Professor Einstein educational robots a year. Chief marketing officer Jeanne Lim won’t say whether it’s profitable.
For now, artificial intelligence is best at doing specific tasks. It’s another thing entirely for machines to learn a new ability, generalize that knowledge and apply it in different contexts, partly because of the massive amount of computing power needed to process such information so quickly.
“We’re really very far from the kind of AI and robotics that you see in movies like ‘Blade Runner,’” said Pascale Fung, an engineering professor at Hong Kong University of Science and Technology. “Sorry to disappoint you.”
