     TOKYO-A child-like robot that combines the roles of nurse,companion and security guard

is to go on the market to help the growing ranks of elderly Japanese with no one to look after

them.

      The "Wakamaru" robot can walk around a house 24 hours a day,warning family,hospitals

and security firms if it perceives(notices)a problem.It will,for example,call relatives if the owner

fails to get out of the bath.

     Cameras implanted in the "eye-brows" of the robot enable it to "see" as it walks around an

apartment.The images can be sent to the latest cell phones,which display the pictures.

      Mitsubishi Heavy Industries which developed Wakamaru plans to start selling the meter-high

robots for about $15 000.

     Wakamaru,which speaks with either the voice of a boy or girl,is also designed to provide

companionship,greeting its "papa" when he comes home.

     It is the first household robot able to hold simple conversations,based on a vocabulary of

around 10 000 words.It cannot only speak but can understand answers and react accordingly.

     It will ask "Are you all right?" if its owner does not move for some time.If the answer is no,

or there is no answer,it will telephone preset numbers,transmitting images and functioning as a

speakerphone.

     Wakamaru will inform a security firm if there is a loud bang or if an unknown person enters

the house while the owner is out or asleep.It can recognize up to 10 faces . But like most robots

it cannot climb stairs.

     It can be set to remind forgetful people when it is time to take medicine,eat and sleep.

      Mitsubishi adapted Wakamaru from robots which already makes to go around nuclear power

facilities(设施).The idea to use the technology in the home came from a company employee.

     The project chief said:"Looking at the ageing of society and the falling birth rate we decide that

this could work as a business.We want to offer Wakamaru as a product that helps society.

     The technology has gained nation-wide publicity in Japan among increasing concern over how

to look after the ever-growing number of old people.The life expectancy of Japanese women has

shot up to almost 85,the highest in the world.

      At the same time,extended families are being replaced by nuclear families.This has left many

Japanese anxious about their elderly parents,whom they rarely see because of their long hours at

the office.
