日本：老齡社會？機(jī)器人來幫忙

到2055年，日本65歲以上的人將占人口總數(shù)的40%。為了減輕勞動(dòng)年齡人口對老年人的贍養(yǎng)負(fù)擔(dān)，日本的研究人員們正在爭分奪秒地研制機(jī)器人，讓它們來代替人做一些基礎(chǔ)工作。目前，他們已經(jīng)研制出一種吸塵器機(jī)器人，它可以自己坐電梯，逐層打掃大樓衛(wèi)生。

It looks like a washing machine on wheels, but the bulky contraption vacuuming the hallways of a Tokyo high-rise is a robot.
Japanese researchers hope that robots like this one will be the answer to a pressing question hanging over the country -- how to cope with an ageing population and a declining labor force.
The vacuuming machine developed by Fuji Heavy Industries Ltd is already cleaning floors in about 10 buildings around the country, including a 54-floor skyscraper in central Tokyo.
The device operates at night after office workers have gone home. It takes elevators to move from one floor to another.
"The elevator is in cleaning mode. Please do not board," an automated message warns human passengers as the droid's wheels whir to life and the robot rolls inside.
Such robots capable of operating in homes, offices and other venues outside factories are still rare even in Japan, a powerhouse in the field of robotics and home to roughly 40 percent of the world's industrial robots.
Japanese researchers are racing against time to build robots smart enough to serve the needs of the elderly in a country in which 40 percent of the population will be over 65 by 2055.
As Japan's population grows older and its labor force shrinks, researchers say new types of robots will play a major role as there simply won't be enough people to do these jobs.
"In the type of ageing society that we foresee, the situation will likely get to the point where there will be little choice but to get some help from them (robots)," said Isao Shimoyama, dean of the University of Tokyo's Graduate School of Information Science and Technology.
