Predictions of many robots in industry have yet come true. For ten years or more, manufacturers of big robots have explained how their machines can make industry more competitive and productive. The maker for (21) robots is oversupplied now, and the driving force of the robotics(机器人学) revolution is (22) to be with makers of machines that handle a few kilos at most."Heavy-robot manufacturers are in some difficulty (23) finding customer. They are offering big (24) just to get in the door. There has been a (23) growth everywhere in the numbers of robots, so we admit we are either deceiving (26) or that the market is slowly growing. "said John Reekie, chairman of Colen Robotics. "The following things must happen (27) the robotics revolution to occur. We must achieve widespread robot literacy, (28) there has been a computer (29) program, there must be a robot prices.

But Colen with others and departments in universities such as Surrey, Manchester, and Durham possess an advantage (33) . the giants. The big companies sell very expensive (34) to businesses with expert knowledge in automation. The (35) companies make robots for teaching people, and now they have realized that there is a need for small, (36) robots that they can meet.The little companies either bring their educational machines (37) an industrial standard or design from the start. One technique that they all adopt is to choose (38) components where possible. The major cost of making (39) their models is the electronics, which will fall in price. There is (40) scope for reductions in mechanical costs. The sue of standard parts, which are easily replaced, should give these robots a mechanical life of something in the order of five years. 21().

Personal space, an updated form of Edward T. Hall’s 1966 proxemics, is the region surrounding each person, or that area which a person considers his domain or territory. Often if entered by another being without this being desired, it makes them feel uncomfortable. The amount of space a being (person, plant, animal) needs falls into two categories, individuate individual physical space (determined by imagined boundaries), and the space au individual considers theirs to live in (often called habitat). What distance is appropriate for a particular social situation depends on culture. It is also a matter of personal preference. Personal space is highly variable. Those who live in a densely populated environment tend to have smaller personal space requirements. Thus a resident of India may have a smaller personal space than someone who is home on the Mongolian steppe, both in regard to home and individual. Personal space can be determined on a habitat level by profession, livelihood, and occupation. It can also be heavily affected by a person’s position in society, with the more affluent a person being the larger personal space they demand. While it is highly variable and difficult to measure accurately the best estimates for personal physical space place it at about 24.5 inches (60 centimeters) on either side, 27.5 inches (70 centimeters) in front and 15.75 inches (40 centimeters) behind for an average westerner. In certain circumstances people can accept having their personal space violated. For instance in romantic encounters the stress from allowing closer personal space distances can be reinterpreted into emotional fervor. Another method of dealing with violated personal space, according to psychologist Robert Sommer, is dehumanization. He argues that, for instance on the subway, crowded people imagine those infiltrating their personal space as inanimate. Changing perceptions about personal space and the fluctuating boundaries of public and private in European culture since the Roman Empire have been explored in "A History of Private Life", under the general editorship of Philippe Aries and Georges Duby, published in English by the Belknap Press. The factor affecting personal space is ______.
