If only Japanese kitchens were this big

A new experimental home robot unveiled by the University of Tokyo and partner Toyota Motor is designed to clean floors, clear serving dishes, pick up clothing and do a variety of other drudgery that will surely inspire a robot revolution one day. But can it be anything more than an expensive demo?

The Home Assistant Robot (HAR) moves around on a wheeled base, has six-jointed hands and laser range finders and stereo cameras to understand its environment; a failure detection function helps it learn from its mistakes. The robot can manipulate furniture and is pretty mean with a sponge mop. Unfortunately, ordinary Japanese kitchens are only a quarter the size of the one in the demo photo, so HAR would have to slim down from its 130 kg (286 lbs) to tackle the real world.

Honda took the wraps off Asimo eight years ago now, and last year its lead engineer told me it would be another decade before it goes to market. HAR would not be commercialized for another seven years, according to the research consortium, and my guess is it would be extremely expensive if that ever happens - so maybe the people who could afford one will have really big kitchens.

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.

Fiddle me this

Toyota Motor has unveiled its latest awesome robot musician - a violin player. The Toyota Partner Robot is an addition to the automaker's lineup of gigging droids that includes drummers and trumpet players.

The violinist did a rendition of Elgar's "Pomp and Circumstance" in a display that was dexterous but a tad, er, robotic.

Toyota President Katsuaki Watanabe told reporters the Partner robot will have a big role in helping take care of old people as Japan's population ages rapidly. The firm's robot staff of 100 will be doubled and a new robot research center will be built, he added.

Yet Watanabe admitted Toyota is still exploring possible business models for its humanoid robots.

Robots need to be successful products to have any real impact on everyday life. While the violinist is a nice engineering feat, getting it to tidy up a room and do the laundry would be a real breakthrough.

Toyota to sell Partner Robots

Toyota Motor has marked the 70th anniversary of its founding by announcing a long-term business plan that calls for the commercialization of its humanoid Partner Robots for jobs like housekeeping and nursing support.

The Toyota Global Vision 2020 plan sees robots as a core business for the leading automaker, which also plans to make hybrid technology available for its entire fleet of vehicles.

There were no details on the timing of the commercialization of the Partner Robots, which debuted as a robot orchestra at the 2005 Aichi Expo in Japan.
