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 cellphones, which display the pictures.
Mitsubishi Heavy Industries, which developed Wakamaru, plans to start selling the metre-high robots by April, 2005, for about ＄15,000 Cdn.
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.
    A. The robot can dial proper numbers for help.
B. The robot is likely to have a promising market.
C. The robot has given the Japanese a chance to live longer.
D. The nuclear families have left many elderly Japanese anxious.
