阅读下列短文,从每题所给的四个选项(A、B、C、D)中,选出最佳选项。
Preliminary (初步的) work on the design of suitable walking and stair - climbing mechanisms (装置结构) has already shown that there are no major problems in this field, and the design of arms with the necessary degrees of freedom and of hands for both picking up objects and for gripping (紧握) and rotating (旋转) object indefinitely in either direction is well advanced. Storage batteries (蓄电池) or directly fueled cells (燃料电池) will certainly be well enough developed to provide 1kw for 1 hour with a weight of 20kg or so.
Basically, applied (应用的,实用的) science starts with the clear understanding of a human need and then used all the available (有用的) scientific knowledge to help with the achievement and satisfaction of this need. Helping the housewife by eliminating the routine operation is the outstanding (明显的) human need in the developed countries. The only problem is whether a sufficient (enough) number of applied scientists will have organized and decided to work for the achievement of this and will have the necessary financial backing. We can expect to see that development of a robot will serve a purpose in saving people from burning houses or planes or putting out oil
well fires.
