A child-like robot, Wakamaru, developed by Mitsubishi Heavy Industries of Japan and combining the roles of nurse, companion and security guard, will soon be in the market to look after the growing number of old people with no one to look after them.
Cameras implanted under the “ eyebrows” of the robot enable it to “see’’ as it moves around in a house. The images can be sent to the latest mobile telephones, which can show the pictures. Wakamaru speaks with either the voice of a boy or a girl. It is also designed to provide companionship, greeting its “ papa”, when he comes home. Based on a vocabulary of around 10 000 words, it is the first household robot which is able to hold simple conversations. It can not 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 preset numbers, send images and work as a speakerphone. It can recognize up to 10 faces. It can be set to remind forgetful people when it is time to take medicine, eat and sleep.
However, like most robots, it cannot climb stairs. Mitsubishi developed Wakamaru from robots which have already been made to go around nuclear power facilities(设施). “ Looking at the ageing of society and the falling birth rate we decided that this could work as a business. We want to offer it as a product that helps society,’’ said the project chief. The developers plan to sell the robot from April next year at between 5,000 and 6,000 pound.
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. Therefore, the technology has gained nation-wide publicity in Japan.
