Walking, talking androids have been a sci-fi staple for decades.
In a 2012 article (see link), John Pavlus reports building an intelligent robot in reality is still a matter of getting the right parts and smarts.
Some excerpts:
"The patterns of sensory stimulation that we generate from moving our bodies in space and interacting with our environment are the basic building blocks of cognition," says Rolf Pfeifer, a lead researcher on ECCERobot. "When I grasp a cup, I am inducing sensory stimulation in the hand; in my eyes, from seeing how the scene changes; and proprioceptively [in my muscles], since I can feel its weight.”
In any case, says Pfeifer, building an intelligent humanoid robot – one that "can smoothly interact with humans and human environments in a natural way" – will require breakthroughs in computing and battery efficiency, not to mention a quantum leap in sensory equipment. "A really crucial development will be skin," he says. "Skin is extremely important in the development of intelligence because it provides such rich sensory patterns: touch, temperature, pain, all at once."
A robot with skin and human-like internal anatomy starts to sound less like a robot at all, and more like a synthetic organism – much like David in Prometheus. Which takes us back to the question he asks in the film. Or as Pfeifer more pragmatically puts it: "Why build a robot which is a very fragile and expensive copy of a human being?"
It is a very useful goal, Pfeifer argues. “Even if we still mostly want robots to do specialized tasks, there will be tons of spinoffs from an understanding of humanoid, intelligent behaviour. Yes, we'll draw inspiration from biology. But that doesn't imply that we won't go beyond it.
