[解析] Robots We are now living in a world in which robots are taking over much of the work. Robots make our cars, fly our planes and work out wages. Robots need some human features to do human work. First of all they need some kind of brain. Their brain is a computer, which has a memory to remember instructions. Another essential feature of many robots is an arm that can do the kind of things that human beings can with their arms. One-armed robots are now coming into widespread use in industry. They are being used, for example, on car assembly lines. The great advantage of robots over human workers is that they can work non-stop for long periods.
