A. When Takanori Shibata began working on robots in the early 1990s, he had something practical in mind, perhaps to help the elderly with their daily chores. But he soon realized that robots were not really able to do anything useful, so he decided to make a robot that did not even try—but that could nevertheless deliver real benefits.
B. The result of his labors, Paro, has been in development since 1998. It is 57cm long and looks like a baby seal. Thanks to an array of sub-skin sensors, it responds amiably to stroking; and though it cannot walk, it can turn its head at the sound of a human voice and tell one voice from another. It is a comforting and gentle presence in your arms, on your lap or on a table top, where it gives the impression of following a conversation. The best thing about it is that it seems to be helping in the care of people with dementia (痴呆) and other health problems.
