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."

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.

Drinks maker giving away robots

Major Japanese brewer Suntory is giving away free robots - one hundred Roomba 570 vacuum cleaners from iRobot as well as a thousand of these cute little original tabletop bots it calls Zerobo. The giveaway is to promote the relaunch of Suntory's Dakara health drink.

Zerobo, named for the zero sugar, calories and salt in Dakara, is pretty nifty for a freebie. It uses infrared sensors and bumpers to detect obstacles and differences in surface levels. It can do light vacuuming in a random pattern like Roomba and respond to voice commands. You can Zerobo saying "Good morning" and other Japanese words on this site.

Another prize is a Dakara-shaped vacuum cleaner that fits in the palm of your hand. Powered through a USB connection, it can be used to clean your PC keyboard.
