Looking technology in the eye

In a decade or so, people may not have to tidy their house, clean up after the dog, or even nag their spouse to do chores. A friendly, human-like robot will take care of routine tasks, and it won't whine or fight back. If technologists' predictions bear out, this second coming of robots could be more pervasive than the first in the '60s, when industrial robots revolutionized manufacturing. Designed to mimic the look and gestures of humans, the new breed of personal robots eventually may have artificial skin and muscles, as well as eye and facial expressions, and they might speak more naturally. But for this rapidly evolving field to take off, scientists will have to improve the quality and reliability of electronics first, and companies will have to find the application that every household must have.
