Robots that look human
The man who mistook his girlfriend for a robotFrom the article:
- And that, it turns out, makes Hanson's heads unique. The humanoids that have made news the past few years—Asimo, Grace, Kismet—are fine robots all, talented, versatile, smart, friendly. Asimo, the plastic-suited Honda humanoid, walks on two legs and welcomes visitors to the factory that builds it. Carnegie Mellon's Grace, a six-foot-tall conglomeration of metal parts on wheels topped with an animated computer-monitor face, registered itself for a conference last year, found its way to the right room, and gave a presentation. Kismet, the media darling of a few years back, looks people in the eye, smiles when they do, and learns just like a baby would, by watching and copying. Who wouldn't like these three? Other robots are being designed to work as nurses, tutors, servants and companions. But despite their talents, every one of these robots looks ... well, like a robot. They're sometimes appealing in a cartoonish sort of way, but they're metallic, awkward, clunky.
Not Hanson's heads. And for that reason, the next morning at 10:30 sharp the reporters are waiting—a roomful of them—and TV cameras are here to capture the debut of Hanson's latest, most advanced model. Hanson, 33, walks in and sets something on a table. It's a backless head, bolted to a wooden platform, but it's got a face, a real face, with soft flesh-toned polymer skin and finely sculpted features and high cheekbones and big blue eyes. Hanson hooks it up to his laptop, fiddles with the wires. He's not saying much; it might be an awkward moment except for the fact that everyone else is too busy checking out the head to notice. Then Hanson taps a few keys and . . . it moves. It looks left and right. It smiles. It frowns, sneers, knits its brows anxiously. Now the questions start, and Hanson is in his element: The head's got 24 servomotors, he says, covering the major muscles in the human face. It's got digital cameras in its eyes, to watch the people watching it, and new software will soon let the head mimic viewers. Its name is K-Bot, and it's modeled after Kristen Nelson, his lab assistant.

The best place to learn Chinese online is in China. However, we understand that it isn't always possible to move here to learn Chinese language. The next best thing is to study with our experienced teachers in a virtual classroom. Online students enjoy the same excellent way of mandarin online lessons and custom designed courseware that we provide for our face to face clients.
