U.S., Japan go separate ways in robots

Here's an excerpt from an article I wrote for The Japan Times based on my interview with PW Singer, author of a provocative new book about U.S. military robots, Wired For War.

Unmanned aerial vehicles (UAVs) like the MQ-1 Predator, developed by California-based General Atomics, circle the skies of Iraq, Pakistan and Afghanistan gathering intelligence and taking out targets with Hellfire missiles. Tireless and devoid of emotion, UAVs have proven remarkably effective.... So comprehensive is the automation of the military that, under the $230 billion Future Combat Systems program, brigades will have more unmanned vehicles than manned vehicles by 2015.

The United States is creating a grand robotic army.

"Military robots are an even more revolutionary technology than the atomic bomb," says Singer. "The robotics revolution in war has a critical difference — it affects the 'who' of war, not only the warriors' experience, but the very identity of the warriors themselves."

Yokohama hosts big bot fest

Yokohama will host a three-day robot extravaganza in October 2008 that will showcase many of Japan's most high-profile machines.

The sensibly titled Robo Japan 2008 will feature Honda's Asimo, Mitsubishi's Wakamaru, Robo-Garage's Chroino and others at Pacifico Yokohama October 11-13. Participants will include 28 companies, seven schools and seven groups. The theme will be "robots in everyday life."

It'll be a fun event for kids, but most of the robots on display have been around since at least the 2005 Aichi Expo.

Quest for practical robots

A recent article in Newsweek quotes me as saying that Japanese are too in love with robots.

It's a point that is seldom discussed - while U.S. firms like iRobot have turned out hit mass-consumer products such as Roomba that are pragmatic, Japanese companies are still obsessed with building bipedal machines that are very cool but pretty useless.

It's the Astro Boy complex at work. The idea of building a humanoid robot just like the machines of science fiction makes for some very slickly designed robots, but many are marketplace failures.

As the article points out, it's no surprise that Roomba the robot vacuum cleaner has sold over 3 million units, but Mitsubishi Heavy Industries sold only a few dozen of its humanoid communication robot Wakamaru. Granted, the latter was over one hundred times more expensive.

But Japanese engineers are learning that things called "robot" should be practical too. Earlier this month, Toyota unveiled its Winglet electric scooter, similar to a Segway and incorporating robotics technology from Sony's Aibo lab. The automaker calls it "a personal transport assistance robot." Toyota's other robots include a band of humanoid musicians - impressive but nowhere near practical yet. The Winglet, though, is a brilliant fusion of design and functionality.

Metrobot squad infiltrates Seoul subway

South Koreans have drawn attention for plans to have a robot in every home by 2010. That faraway goal came a step closer today when the Seoul subway began deploying a small army of service robots called Metrobots to assist travelers.

The humanoid machines can provide information about subway fees, restaurants, tourist attractions and maps in Korean and English. Ten Metrobots are to work at City Hall and nine other transfer stations on the busy Metropolitan Subway system.

What with Japan's Asimo and Korea's Hubo in near-parallel development, I wonder whether this bit of one-upmanship in the robot arms race will see a flood of Wakamaru bots hitting the Tokyo underground.

Humanoid for hire

Get your artificial receptionist/valet while supplies last. Japanese manufacturer Mitsubishi Heavy Industries has announced that its humanoid communication robot Wakamaru is now available for rent.

Wakamaru is a sophisticated robot with vision, auditory and touch sensors. The rental project is aimed at businesses, hospitals and events, where the droid will do receptionist and guidance duties. Wakamaru can understand about 10,000 words, retrieve information or emails from the Net with its wireless LAN link, and do a mean upper-body aerobics routine.

The daily rental fee varies according to the lease length. For a lease of 1-5 days, it's 120,000 yen ($970), while 21-30 days is only 20,000 yen ($160). Shipping and management charges extra. The rentals will come with touch panels that can display venue maps and other info.
