artificial helpers and attempts to create them has a long history and is the basis
of much science fiction. robots are generally used to help with jobs that are too dirty or boring for most
human beings.
the first prgrammable humanoid robot was about 1206 ad. we can make a robot to
look like almost anything we want. the most fantasized about are ones that have a
humanoid appearance. think of a repetative task and generally there is probably one
on th market that can do what you want. manipulators are the way an object is manipulated. this generally is done by
grippers, or effectors. scientists and researchers are constantly trying to hone the robot into something
better.

people who go all lou dobbs about robots. people say things like: all robots look
alike. robots should speak english. robots are taking all the jobs. robots dont pay
enough taxes. robots reproduce like bunnies. i dont want my child playing with a robot,
or goodness gracious, marrying a robot. an acquaintance of mine, who discriminates against robots, but never actually
met one, received a roomba for christmas i pushed its power button, she said. it was
so cute when it sounded the charge, and scurried across the floor gobbling up dust
bunnies. i love roomba, she said. but i still dont like robots. it is typical to think
that your robot is somehow different from other robots. those other robots can not
be trusted. it may take another generation, one where our children are raised amongst robots,
for them to gain acceptance. like the washing machine and the automobile, robots are
part of our future.
it is true that robots can be hard to tell apart. i remember sarah connor in
terminator ii. she damn near wet her pants when a series 800-model 101 showed up,
a few years after shed sent its twin to the scrap heap. given a little time, however,
she got acquainted with the big, muscle-bound machine. she fantasized about keeping
him on as dad and husband. after all, he got along well with the boy, was a good provider,
and would stop at nothing to protect her family. although robots are loyal and dependable, they do screw up once in a while. im
thinking of hal in 2001, a space odyssey. he definitely made a mistake of judgment.
i still think he deserved a second chance? for every hal, there are dozens of r2-d2s
and 3cpos. and that cute little wall-e. occasionally, there is a bad egg, like ed-209 in robocop. or the battle droids
in star wars. but are they worse than rottweilers and pit bulls? surely, some of them
can be rehabilitated, and make good pets. from an economic point of view, you cant beat robots. they work day and night.
they rarely call in sick. they add to the nations gdp, and dont require pensions or
health care. they are terrific with numbers and rarely have math anxiety. robodoc
performs delicate surgeries 24/7 and he never gets the shakes. but, you ask, what if they go into politics? will they impose their culture, their
language, and their way of life on us? forget about it. no one can resist big macs,
vacations to disneyland, and shopping at walmart. this is america.. face it, robots are here to stay. they are willing to do anything. they make great
maids and gardeners, sweepers and scrubbers, mowers and choppers. there are robots
that care for the elderly, wash their dirty bottoms and soon perhaps, play yahtzee
with them. there are robots that imitate pets yet dont require walks nor litter boxes.
even robots thatll go the fridge, grab a cold beer, and bring it to you. if its eager
to watch the super bowl, and play wii tennis, you got yourself a great roommate. as far as intermarriage with a robot, didnt they try that in the stepford wives?
maybe it was just too soon. 3
most of us are still of of the mindset that robotics is something that is rather
futuristic. we still may have pictures in our head of humanoid robots, flailing their
arms and either attacking the earth from other planets or perhaps protecting us in
some way or another. the fact of the matter is, humanoid robots are still very much
futuristic but much of the future of robots is already in existence today. robots
are used in a number of different settings that you might find rather interesting.
here is a little bit about the future of robotics and the fact that much of it is
already in existence with what we are doing now. one of the ways in which robots are most often used is in an industrial setting.
the automotive industry, for example, makes use of robots on their assembly lines to do a number
of different tasks. unfortunately, this has put many individuals out of a job because
the robot was able to do what they used to do on the assembly line more efficiently.
not only that, once the robot is put into place they are able to take care of these
repetitive tasks, 24 hours a day, 365 days a year. one of the ways in which robotics is used on a regular basis is in spot welding.
although this used to require a human touch, much of the welding that is now done
by robots is so accurate and precise that a human could not possibly take care of
it in that way. many times, this welding needs to be done in an assembly line
environment so the same simple task is done over and over again. it will be difficult
for anybody to improve on what is already existing in these robotics unless they make
them less apt to have difficulties from breaking down. robots are also able to help us to get out of dangerous situations in many cases.
a good example of this is spring painting. humans used to have to take care of spray
painting in the automotive industry and other industrial settings. this put them at
risk because they were constantly being exposed to dangerous chemicals, even if they
wore protective clothing. a robot is not only able to be in these rooms without having
to worry about health concerns, they are able to do the painting more evenly and
accurately than their human counterparts. 4
developing a humanoid robot has long since captured the human imagination and
will be the continued focus in the future of robotics. scientists say there are two
obstacles to creating a robot with human or super-human intelligence: vision and
processing sensory information. it is almost motor vehicle production is one area where robotics automation is already being
used. yet imagine a world where we can read, have a glass of wine, talk freely on
our cell phones or take a nap while our personal automobile drives itself from our
workplace to our doorstep. or perhaps well abandon the wheeled prototypes altogether
and kick back in our personal flying car like numerous science fiction films predict.
so how far are we from such a future? 机器人是机器人的科学技术和应用。人造佣工，并尝试建立他们的故事，有着悠久的历
史，是许多科幻小说的基础上。 机器人通常用于帮助工作，是对大多数人过脏或无聊。篇五：计算机专业英语学习的重
要性演讲稿
计算机专业英语学习的重要性（演讲稿） 尊敬的老师，亲爱的同学们，大家好！ 我是08级计科本班的xxx ，很高兴有机会同大家在一起做一番学习方面的交流，作为计
算机学院的学生，因为比较新的技术计算机方面的书籍一般都是英文的书，今天我主要讲一
下英语学习，
没有计算机英语做基础，是学不好计算机的！ 英语学习的重要性众人明了，举国上下、男女老小都在学习英语！英语学习的目的是为
了服务我们的生活、工作，但现在社会中的英语学习性质打上了形式主义的烙记，偏离了学
习根本目的，也浸染了中国科举考试制度陋习烙印，要不得！学习了12年英语的大学毕业生
对计算机中的专业英语陌生，怪不怪？不怪！因为中国的教育是从科考制度的历史中走过来
的。
在某计算机社会培训学校，竟然还有人花大价钱宣扬“没有计算机英语，也可以学好计
算机”的谬论：说这样话的人应该很懂计算机的，他自己计算机专业英语很好，他的这种愚
弄人的言论是带有鲜明商业目的的欺诈宣传行为，大家一定警惕！ 没有计算机英语，你看的懂dos 下的全英文命令吗？ 安装操作系统，没有计算机英语知识，bios 你就没办法； 计算机操作系统、应用软件的底层开发编程语言文字都是用英语写的，没有计算机英语，
你能学的好程序设计吗？
没有计算机英语知识，说去“从事计算机科学与技术研究”，那是一种搞笑！世界上最先
进的科学技术知识，80%以上用英语记叙、传播的，计算机领域最先进的技术、理论都是用英
语发表、记载的。
中国的计算机技术应用、理论研究与世界先进水平相比，有较大差距情有可原，但与发
展中国家印度相比的距离产生的主要原因之一是：英语是印度官方语言之一，印度人在英语
上占有了优越条件。我国政府、社会认识到了这样的客观现实状况，所以有了现在全社会加
紧学习英语的局面。
如果你要学好计算机，就必须学习实在的计算机英语！ 为什麼我们一再读文法、背单字，却因句型不熟而不能立即运用，总是背背忘忘，而无
法学好英语。事实上，学好英文有三大要件：
（一） 培养正确的语法习惯。
（二） 训练用英语思考的能力。
（三） 进行实际的会话练习。 练好基本功是学好英语的必要条件，没有扎实的英语基础，就谈不上继续学习，更谈不
上有所成就。要想基本功扎实，必须全神贯注地认真听讲, 上好每一节课，提高课堂效率，脚
踏实地、一步一个脚印地，在大一、大二，同学们会开始英语课程，一是为了考过英语四六
级 ，但更重的是英语已经渗透了渗透了各行各业，学习英语是必需的，计算机学院的学生更
是有必要学好英语。
单词的学习是英语学习的基础：大家必须做到以下 一是持之以恒：每天坚持记忆一定量的词汇，过几天再回头复习一次，这样周期循环，
反复记忆，需要注意的是，一旦开始，就要坚持下来，千万不能半途而废，切不可三天打鱼，
两天晒网。
二是良好的记忆方法：记忆单词的方法很多，学无定法，但学有良法 .我觉得在句子中
记忆单词是个不错的方法. 要想理解一个句子, 就必须明白句子中每个单词的含义. 看句子的
时候首先理解句子中每个单词的含义, 然后就是对句子结构进行分析. 这样一个小小的句子也
蕴藏了很多的知识点.
三就是要背文章。我觉得背是为了让你更加熟悉句型，比如说和别人交谈的时候如果你
有一句背得很熟的话。就可以脱口而出，不用思考，这就是背的好处，要多背范文, 比如英语
四六级的范文可以供你参考，这样有利于你早日考过英语四六级。 学习英语, 培养兴趣最重要 我们可以听听英文歌曲, 看看欧美电影. 但是我们并不是当成
娱乐. 看电影的时候电影最好是带英文字幕的, 自己用心去听, 先不要看字幕, 看看理解多少.
能把一部电影中每个句子都完全的理解, 也是一种很大的成就. 同学们，大学生活刚刚开始，千万不要在无拘无束的大学生活迷失自己，同学应该知道，
在软件程序开发的代码基本上英语写出来的，这样就决定了英语对计算机专业同学的重要性，
大一是不让参加四六级考试的，但是作为大一的同学，你们有充分的时间去上自习，去做自
己想做的事情，但是我知道大家的军训正在进行，大家会很苦、很累，但是大家一定要坚持
下来，要知道：不经历风雨怎能见彩虹，军训过去之后，你们就会知道这短短的二十天会成
为你人生中美好的回忆，同样也会成为你人生中宝贵的财富。 无论学习哪一门科学知识，都不会是一件轻而易举的事情，都必须有所付出，不劳而获
不是没有，只是概率太低，就像你买彩票中得3.6亿元的大奖一样，你是不会成为那一位 幸运者的，他比遭雷劈的概率还要低。
