...and dirty dishes, house cleaning, and other domestic chores. That's the goal of Anybots, a Silicon Valley startup founded by Trevor Blackwell. The company has been in the news before, but the whole thing is so intriguing we dispatched Automaton correspondent Anders Frick to get more details on the technology. Here's his report:

Economists like to say that the one kind of work you can’t move offshore is personal service, but what if remote-controlled robots become practical?

Trevor Blackwell loves robots, the humanoid kind that populate old sci-fi movies, and like many other roboticists, he thinks there may be a role for them to play around the house. He differs from most, however, in the economic rationale he offers.

Blackwell sees a future in which a low-paid worker from India might remotely control a robot in your kitchen, taking on tasks that today might be assigned to a servant. Blackwell believes that this is the Next Big Thing, and that thousands of homes will be using his robots to clean, cook, and serve meals. This scheme would effectively allow rich countries to import labor -- without the laborer.

To realize that vision, Blackwell founded Anybots in Mountain View, Calif., in 2001, after his last company, Viaweb, was bought by Yahoo for US $45 million in 1998. Blackwell is also a partner in the startup funding firm Y Combinator, which has invested in nearly 60 different startups during the last three years.

He is currently testing both a legged robot, named Dexter, and a wheeled one, named Monty. They now perform only a few, limited tasks, such as serving coffee and operating a hammer drill. It turns out Monty’s the nimbler of the two. “Robots with wheels are both faster and more stable,” Blackwell says.

Each robot has a built-in gyroscope in the torso, position- and force-sensors in the joints and fingers, and magnetic motion sensors in the arms. Their moving parts are actuated by pneumatic plungers and valves, powered by electricity from carbon aerogel ultra capacitors that can go half an hour on a charge.

The 16 cameras carried on different parts of the robots’ bodies supply video to 10 remotely placed monitors. In the beginning, Blackwell says, engineers and technicians will use the robots to steer in particularly dangerous environments -- say, the site of a nuclear or chemical accident. Such work should get the kinks out. That way, when robots go into mass-production for the consumer market, they will be sufficiently reliable, and perhaps also toxic waste-proof, which might come in handy when dealing with some people's dirty socks.

Hexapod robots have long fascinated roboticists, and now you can find the six-legged creatures swimming in the Caribbean or harvesting timber in Finland. There's also a legion of do-it-yourselfers creating their own hexapods just because it's fun.

One of them is J. de Vries, a 42-year-old webdesigner from Neustrelitz, Germany. When he's not taking care of his daughters (15-month twins), de Vries works on Marvin, the hexapod in the image below.

Marvin uses nine Atmel microcontrollers (ATmega16, 32, and 64) and 20 servomotors. It's only 30 to 40 percent finished, de Vries says, adding that he plans to include some onboard sensors after perfecting Marvin's locomotion.

"I don't have any degree in engineering and I never saw an university from inside," de Vries says. "But since I was 12 years old, my dream was to build a robot. ... Last year I learned a lot about microcontrollers, servomotors and the required electronics while building a quadcopter with brushless motors. And that was the beginning of realizing my old robot dream."

De Vries has a web page with videos, images, and technical details on Marvin (in German).

I finally had time to read Robin Marantz Henig's 8000-word piece on sociable robots in the New York Times Magazine. In the article, Henig, a contributing writer for the magazine, describes what scientists mean when they talk about "sociable robots," how such robots were designed to learn by interacting with their environments, and what are the issues involving robot learning, robot emotion, and robot boyfriends.

Henig does a great job explaining how the robots work, sometimes by "peeking behind the curtain" -- the robots are mostly MIT robots, old and new, including the metal torso Cog, the bushy-eyebrowed Kismet, the talkative head Mertz, the mop-topped Autom, the Gremlinlike Leonardo, the skyscraperish Domo, and the rubbery bulgy-eyed Rodney (OK, joking about this last one).

More interesting, perhaps, Henig describes instances in which the robots misbehave, or work in a somewhat disappointing way, and hey, that's how engineering happens in the real world, so it was neat to see that in the article as well (by the way, I loved the cover headline, which to me captures the essence of this emerging field: "It Understands (Sort Of)." An excerpt:

Today’s humanoids are not the sophisticated machines we might have expected by now, which just shows how complicated a task it was that scientists embarked on 15 years ago when they began working on a robot that could think. . . . They are, instead, hunks of metal tethered to computers, which need their human designers to get them going and to smooth the hiccups along the way.

But these early incarnations of sociable robots are also much more than meets the eye. Bill Gates has said that personal robotics today is at the stage that personal computers were in the mid-1970s. . . . In much the same way, the robots being built today, still unwieldy and temperamental even in the most capable hands, probably offer only hints of the way we might be using robots in another 30 years.

After reading the article, I wanted to see some of those machines in action, and it's just great you can find so many videos of them (the Times posted a bunch on the article's web page). But as a writer myself I also wanted to know more about Henig's experience writing the article. Having just returned from vacation, she was kind enough to promptly answer my questions -- thanks, Robin! (Follow the link below to read the Q&A.)

MIT researchers have created a wearable robotic exoskeleton to help soldiers carry heavier loads on their backpacks. Powered legs like those could one day help elderly and disabled people gain more mobility and carry things around more easily, but since this is DARPA funded work soldiers have priority. Sorry, grandma.

The MIT exoskeleton consists of a pair of mechanical legs with a mounted backpack frame. The mechanical legs strap to the user's own legs and support much of the pack's weight by transferring it to the ground. The MIT researchers, led by Hugh Herr at Media Lab's Biomechatronics Group, report in the September issue of the International Journal of Humanoid Robotics that their prototype can take on 80 percent of an 36-kg load carried on a person's back.

And how does it work?

For anyone in the Boston, Mass area, you might be interested in this event at MIT tomorrow (Wednesday) night, a session called "Robots: The Next Wave of the Robot Revolution" that will "explore the advancing robot invasion across all of those sectors." There's a panel of speakers from a few robotics companies, networking receptions, and recruiting (I'll be there representing Bluefin). There's a small registration fee, though it's free for students.
