Dude?

Mr. McMullen’s new project, which he is calling Realbotix, is an attempt to animate the doll. He has assembled a small team that includes engineers who have worked for Hanson Robotics, a robotics lab that produces shockingly lifelike humanoid robots.

Mr. McMullen is first focusing on developing convincing artificial intelligence, and a robotic head that can blink and open and close its mouth. He’s also working to integrate other emerging technologies, like a mobile app that acts like a virtual assistant and companion, and virtual reality headsets that can be used separately or in tandem with the physical doll.

One of the challenges that Mr. McMullen will have to contend with is the so-called uncanny valley. It is a concept first written about in 1970 by a Japanese researcher, that says people’s responses to robots will shift sharply from empathy to revulsion the more closely the robots resemble humans. In other words, something robotic that looks alive, but is not completely convincing, will creep people out.
