Two teams working to develop the most humanlike robots on the planet - often dubbed androids - are Hanson Robotics and Hiroshi Ishiguro Laboratories. Dr. David Hanson leads the engineers and designers that created Sophia, the team's most advanced android to date. Sophia's lifelike skin is made from patented silicon and she can emulate more than 62 facial expressions. Cameras inside her eyes," combined with computer algorithms, enable her to "see," follow faces and appear to make eye contact and recognize individuals. A combination of ... voice recognition technology and other tools enable Sophia to process speech, chat and get smarter over time. "Our goal is that she will be as conscious, creative and capable as any human," said Hanson. "We are designing these robots to serve in health care, therapy, education and customer service applications." Hanson said that one day robots will be indistinguishable from humans. "The artificial intelligence will evolve to the point where they will truly be our friends," he said. Hanson plans to announce pricing and availability of his humanlike robots later this year. "Gemini" is Latin name for "twins" and the root of "Geminoid," a robot created by Hiroshi Ishiguro ... in order to study humans, which he believes are not that different from robots. "We are more autonomous and more intelligent - that's it," he said. His own tests found that 80 percent of people greeted his most human-like androids with a "hello," initially mistaking them for real people.
