A robot friend in every home: Toyota wants them to help with chores, serve as companions

Toyota Motor Corp. has sold enough cars to put one outside every Japanese home. Now it wants to put robots inside.

Well-known for its automated assembly lines, Toyota sees a not-so-far-off future in which robots transcend the factory and become commonplace in homes, helping with chores — and even offering companionship — in an aging society where a quarter of the population is over 65 and millions of seniors live alone.

Machines have become much smarter in the last decade or so. Yet, every attempt to build one that can do simple things like load a washing machine or carry groceries encounters the same basic, physical problem — the stronger a robot gets, the heavier and more dangerous it becomes.

What Toyota has going for it are $29 billion in cash reserves, a new artificial intelligence research center and a well-respected inventor, Gill Pratt, heading its effort.

“This is a company with so many resources that you can never ignore them,” said Morten Paulsen, a Tokyo-based analyst at CLSA Japan Securities, who’s covered the robotics industry for decades.

Toyota has been experimenting with robots since at least 2004, when it unveiled a trumpet-playing humanoid with artificial lips, lungs and movable fingers that could accompany an actual human orchestra.

Since then research has become more practical. Toyota’s latest android, the T-HR3, is a kind of avatar that can be manipulated remotely via wearable controls, with vision goggles that allow users to see through the machine’s camera-eyes.

The device could one day serve as arms and legs for the bedridden, or as a surrogate for relief workers in disaster zones.

In 2015 the automaker spent a billion dollars to open its AI-focused Toyota Research Institute in Silicon Valley.

Last year it set up a $100 million fund to invest in start-ups and new robotics technology. This year the company restructured its Partner Robot division to speed decision-making and shorten development time.

“There’s internal pressure all of a sudden to move faster,” senior manager Keisuke Suga said at a recent industry forum near the automaker’s Toyota City headquarters.

The road to robots has had its setbacks. In 2011, Toyota demonstrated a machine for lifting patients in and out of bed, but engineers had only tested it on healthy volunteers.

Once they discovered that the frail and elderly required a more delicate touch, the product was shelved.

Most of the $2.1 billion spent by consumers last year on householdrobots was for automated vacuum cleaners and lawnmowers.

Toyota says the need for elder-care will change that. The automaker illustrates the point with a chart showing Japan’s inverted age-pyramid in the year 2050, when a third-fewer workers will have to support twice as many old people as today.

Some 22 percent of the world’s population will be over 60 by then, according to the World Health Organization.

Toyota’s Human Support Robot, or HSR, is the machine the automaker sees as closest to making the leap from lab to living room.

The robot-equivalent of a Corolla — all function and no frills — the HSR is basically a retractable arm on wheels with a video screen on top and two large camera eyes that give it the rudiments of a face.

It weighs as much as a half-dozen bowling balls, but can lift only a 1.2-kilogram payload — 2.6 pounds, about the weight of a medium-sized water bottle.
