　　C

　　A child－like robot that combines the roles of nurses, companions and security guards is to go on the market to help the growing elderly Japanese with no one to look after them.

　　The “Wakamaru” robot can walk around a house 24 hours a day, warning families, hospitals and security firms if it notices a problem. It will, for example, call relatives if the owner fails to get out of the bath.

　　Cameras implanted in the “eyebrows” 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 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 also 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 present numbers, passing images and functioning as a speakerphone.
