Although people of that era didn’t have a term to describe what we would eventually call a robot they were nevertheless imagining mechanisms that could perform human-like tasks. In medieval times, automatons, human-like figures run by hidden mechanisms, were used to impress peasant worshippers in church into believing in a higher power. The automatons, like the clock jack pictured here, created the illusion of self-motion (moving without assistance). The clock jack was a mechanical figure that could strike time on a bell with its axe. This technology was virtually unheard of in the 13th century. So imagine how aweinspiring an automaton was to someone just like you! In the 18th century, miniature automatons became popular as toys for the very rich. They were made to look and move like humans or small animals. The pretty musician in the picture was built around 1890. She can turn her head from side to side while playing the instrument with her hands and keeping time with her foot. In literature, humankind’s vivid imagination has often reflected our fascination with the idea of creating artificial life. In 1818, Mary Shelly wrote Frankenstein, a story about the construction of a human-like creature. For Shelly, a robot looked like man but had the ability to function like a machine. It was built of human components, which could be held together by nuts and bolts. Notice there are even clips to hold the top of the head together! Shelly considered that a robot had to be bigger than a regular person and had to have super human strength. In 1921, Karel Capek, a Czech playwright, came up with an intelligent, artificially created person, which he called “robot”. The word “robot” is Czech for worker, and was gradually incorporated into the English language without being translated. As you can see, even a hundred years after Shelly’s Frankenstein, Capek’s idea of a robot is still one in which the creation resembles the human form. You can see in the picture that the robot looks much more rigid and machine-like than the woman standing next to it . While the concept of a robot has been around for a very long time, it wasn’t until the 1940’s that the modern day robot was born, with the arrival of computers. The term robotics refers to the study and use of robots; it came about in 1941 and was first adopted by Isaac Asimov, a scientist and writer. It was Asimov who also proposed the following “Laws of Robotics” in his short story Runaround: One, a robot may not injure a human being or through inaction, allow a human being to come to harm. … Two, (…) a robot must obey the orders given it by human beings except where such orders would conflict with the First Law. … Three, a robot must protect its own existence as long as such protection does not conflict with the First or Second Laws. Isaac Asimov i The robot really became a popular concept during the late 1950’s and early 1960’s. With the automotive industry in full expansion at that time,industrial robots were employed to help factory operators. Industrial robots do not have the imaginative, human-like appearance that we have been dreaming of throughout the ages. They are computer-controlled manipulators, like arms and hands, which can weld or spray paint cars as they roll down an assembly line. In fact, industrial robots are so unlike the conception of robots held in the past that you might not even recognise one. Did you know that one of the first operational, industrial robots in North America appeared in the early 1960’s in a candy factory in Kitchener, Ontario? A robot can go where humans cannot. In fact, robots were created to help humans, especially in high risk or dangerous situations. A robot can deactivate a bomb, go to the edges of an active volcano, transport dangerous materials, explore the ocean floor and even perform tasks in the most hostile environment known to man: space. So why is space such a hostile environment? First of all, in space there is no oxygen, and temperatures can range from 120 degrees Celsius in the sun and –100 degrees in the dark, when the Earth blocks the sun. Without the proper protection, like a spacecraft or even the EVA suit used by space walkers, survival in space is not possible. When repairs have to be made outside a spacecraft,astronauts are sometimes required to leave the space shuttle or the Space Station. These extravehicular activities are very dangerous, therefore, robots are used to carry out tasks in space in order to limit the number of extravehicular activities Undertaken. What does a space robot look like? As we have discovered, today’s robots do not necessarily resemble humans. A human is made up of a number of different visible components, like a head – where the brain sends messages to the rest of the body; arms and hands to grasp and manoeuvre objects; a torso to which all of the components are attached and legs to move. Oh! And don’t forget the ears, eyes, and mouth to hear see and communicate! Robots need all these different components to Operate. A number of robots make up the Mobile Servicing System. The Mobile Servicing System is Canada’s contribution to the International Space Station. Canada created the Mobile Servicing System to help in the construction of the Space Station; it will first build the Space Station and then help maintain the Station throughout its lifetime. Just like humans have a brain that sends messages to the rest of the body;The re is a main computer that communicates with the robotic system. The Space Station Remote Manipulator System (SSRMS), Canada’s new robotic arm, will be able to lift and move objects the size and mass of the Space Shuttle. The crew of STS-100 with Canadian Space Agency Astronaut Chris Hadfield will deliver and install the new arm to the International Space Station as it orbits high above the Earth. This second generation Canadarm is Canada’s primary contribution to the Station. The Space Vision System (CSVS), another critical piece of Canadian robotics innovation, is comprised of several cameras and targets. These are located in key areas of the Space Station and on the robotic arm; it will serve to pinpoint the exact movement and location of components for the building and maintenance of the Station. So, astronauts from inside the Space Station are able to operate the Mobile Servicing System by using this Space Vision System. Aside from the CSVS, the next Canadian robot to be brought to space is the SSRMS. When it is brought to space to be installed to the Space Station during STS-100, its predecessor, the Canadarm will lift it from the payload (the inside) of Space Shuttle Endeavour and bring it to the International Space Station. This will be the first in a series of handshakes in space performed by these robots.

在大腦將消息發(fā)送到身體的其他部分;雙臂和雙手抓握和 操縱對(duì)象;軀干，其中所有的部件都附屬在此，還有腿移動(dòng)。哦！而且不要忘了耳朵，眼睛和嘴巴去聽看到和溝通！機(jī)器人需要所有這些不同的組件操作。 許多機(jī)器人組成的移動(dòng)服務(wù)系統(tǒng)。該移動(dòng)服務(wù)系統(tǒng)是加拿大的貢獻(xiàn)國(guó)際空間站。加拿大創(chuàng)建移動(dòng)服務(wù)系統(tǒng)幫助空間站的建設(shè);它會(huì)先建立空間站，然后幫助維護(hù)空間站其整個(gè)生命周期。 就像人類有一個(gè)大腦發(fā)送消息到身體的其他部位;有與所述機(jī)器人系統(tǒng)進(jìn)行通信的主計(jì)算機(jī)。 空間站遙控器系統(tǒng)（SSRMS）加拿大的新的機(jī)器人手臂，將能夠提升和移動(dòng)對(duì)象，航天飛機(jī)的大小和質(zhì)量。STS-100，加拿大航天局的宇航員克里斯·哈德菲爾德將提供并安裝新的機(jī)械臂到國(guó)際空間站，因?yàn)樗母哕壍涝诘厍蛏戏?。第二代加拿大臂是加拿大通往空間站的主要貢獻(xiàn)。 空間視覺系統(tǒng)（CSVS），加拿大機(jī)器人技術(shù)創(chuàng)新的另一個(gè)關(guān)鍵部分，是由幾個(gè)攝像機(jī)和目標(biāo)。這些位于空間站和機(jī)械臂上的關(guān)鍵部分;它將有助于精確定位部件的精確移動(dòng)和定位該站的建設(shè)和維護(hù)。所以，空間站的宇航員能夠通過(guò)使用這個(gè)空間視覺系統(tǒng)來(lái)操作移動(dòng)服務(wù)系統(tǒng)。 除了空間視覺系統(tǒng)，接下來(lái)加拿大機(jī)器人被帶到空間是SSRMS。當(dāng)它被帶到空間來(lái)安裝到空間站在STS-100，其前身加拿大臂將解除奮進(jìn)號(hào)航天飛機(jī)的有效載荷（內(nèi)部），并把它帶到國(guó)際空間站。這將是在空間中第一次一系列握手行動(dòng)通過(guò)這些機(jī)器人執(zhí)行。 請(qǐng)繼續(xù)關(guān)注有關(guān)機(jī)器人更令人興奮的事實(shí)... 首先我介紹一下機(jī)器人產(chǎn)生的背景，機(jī)器人技術(shù)的發(fā)展，它應(yīng)該說(shuō)是一個(gè)科學(xué)技術(shù)發(fā)展共同的一個(gè)綜合性的結(jié)果，同時(shí)，為社會(huì)經(jīng)濟(jì)發(fā)展產(chǎn)生了一個(gè)重大影響的一門科學(xué)技術(shù)，它的發(fā)展歸功于在第二次世界大戰(zhàn)中各國(guó)加強(qiáng)了經(jīng)濟(jì)的投入，就加強(qiáng)了本國(guó)的經(jīng)濟(jì)的發(fā)展。另一方面它也是生產(chǎn)力發(fā)展的需求的必然結(jié)果，也是人類自身發(fā)展的必然結(jié)果，那么隨著人類的發(fā)展，人們?cè)诓粩嗵接懽匀贿^(guò)程中，在認(rèn)識(shí)和改造自然過(guò)程中，需要能夠解放人的一種奴隸。那么這種奴隸就是代替人們?nèi)ツ軌驈氖聫?fù)雜和繁重的體力勞動(dòng)，實(shí)現(xiàn)人們對(duì)不可達(dá)世界的認(rèn)識(shí)和改造，這也是人們?cè)诳萍及l(fā)展過(guò)程中的一個(gè)客觀需要。 機(jī)器人有三個(gè)發(fā)展階段，那么也就是說(shuō)，我們習(xí)慣于把機(jī)器人分成三類，一種是第一代機(jī)器人，那么也叫示教再現(xiàn)型機(jī)器人，它是通過(guò)一個(gè)計(jì)算機(jī)，來(lái)控制一個(gè)多自由度的一個(gè)機(jī)械，通過(guò)示教存儲(chǔ)程序和信息，工作時(shí)把信息讀取出來(lái)，然后發(fā)出指令，這樣的話機(jī)器人可以重復(fù)的根據(jù)人當(dāng)時(shí)示教的結(jié)果，再現(xiàn)出這種動(dòng)作，比方說(shuō)汽車的點(diǎn)焊機(jī)器人，它只要把這個(gè)點(diǎn)焊的過(guò)程示教完以后，它總是重復(fù)這樣一種工作，它對(duì)于外界的環(huán)境沒(méi)有感知，這個(gè)力操作力的大小，這個(gè)工件存在不存在，焊的好與壞，它并不知道，那么實(shí)際上這種從第一代機(jī)器人，也就存在它這種缺陷，因此，在20世紀(jì)70年代后期，人們開始研究第二代機(jī)器人，叫帶感覺的機(jī)器人，這種帶感覺的機(jī)器人是類似人在某種功能的感覺，比如說(shuō)力覺、觸覺、滑覺、視覺、聽覺和人進(jìn)行相類比，有了各種各樣的感覺，比方說(shuō)在機(jī)器人抓一個(gè)物體的時(shí)候，它實(shí)際上力的大小能感覺出來(lái)，它能夠通過(guò)視覺，能夠去感受和識(shí)別它的形狀、大小、顏色。抓一個(gè)雞蛋，它能通過(guò)一個(gè)觸覺，知道它的力的大小和滑動(dòng)的情況。第三代機(jī)器人，也是我們機(jī)器人學(xué)中一個(gè)理想的所追求的最高級(jí)的階段，叫智能機(jī)器人，那么只要告訴它做什么，不用告訴它怎么去做，它就能完成運(yùn)動(dòng)，感知思維和人機(jī)通訊的這種功能和機(jī)能，那么這個(gè)目前的發(fā)展還是相對(duì)的只是在局部有這種智能的概念和含義，但真正完整意義的這種智能機(jī)器人實(shí)際上并沒(méi)有存在，而只是隨著我們不斷的科學(xué)技術(shù)的發(fā)展，智能的概念越來(lái)越豐富，它內(nèi)涵越來(lái)越寬。? 下邊我簡(jiǎn)單介紹一下工業(yè)機(jī)器人的一些情況。到目前為止，工業(yè)機(jī)器人是最成熟，應(yīng)用最廣泛的一類機(jī)器人，世界總量目前已經(jīng)銷售110萬(wàn)臺(tái)，這是1999年的統(tǒng)計(jì)，但這110萬(wàn)臺(tái)在已經(jīng)進(jìn)行裝備使用的是75萬(wàn)臺(tái)，這個(gè)量也是不小的?？傮w情況看，日本在工業(yè)機(jī)器人這一塊，是首位的，成為機(jī)器人的王國(guó)，美國(guó)發(fā)展也很迅速，目前在新安裝的臺(tái)數(shù)方面，已經(jīng)超過(guò)了日本，中國(guó)剛開始進(jìn)入產(chǎn)業(yè)化的階段，已經(jīng)研制出多種工業(yè)機(jī)器人樣機(jī)，已有小批量在生產(chǎn)中使用。? 點(diǎn)焊機(jī)器人主要是針對(duì)汽車生產(chǎn)線，提高生產(chǎn)效率，提高汽車焊接的質(zhì)量，降低工人的勞動(dòng)強(qiáng)度的一種機(jī)器人。它的特點(diǎn)是通過(guò)機(jī)器人對(duì)兩個(gè)鋼板進(jìn)行點(diǎn)焊的時(shí)候，需要承載一個(gè)很大的焊鉗，一般在幾十公斤以上，那么它的速度要求在每秒鐘一米五到兩米這樣的高速運(yùn)動(dòng)，所以它一般來(lái)說(shuō)有五到六個(gè)自由度，負(fù)載三十到一百二十公斤，工作的空間很大，大概有兩米，這樣一個(gè)球形的工作空間，運(yùn)動(dòng)速度也很高，那么自由度的概念，就是說(shuō)，是相對(duì)獨(dú)立運(yùn)動(dòng)的部件的個(gè)數(shù)，就相當(dāng)于我們?nèi)梭w，腰是一個(gè)回轉(zhuǎn)的自由度，我們大臂可以抬起來(lái)，小臂可以彎曲，那么這就三個(gè)自由度，同時(shí)腕部還有一個(gè)調(diào)整姿態(tài)來(lái)使用的三個(gè)自由度，所以一般的機(jī)器人有六個(gè)自由度，就能把空間的三個(gè)位置，三個(gè)姿態(tài)，機(jī)器人完全實(shí)現(xiàn)，當(dāng)然也有小于六個(gè)自由度的，也有多于六個(gè)自由度的機(jī)器人，只是在不同的需要場(chǎng)合來(lái)配置。? 第二類是服務(wù)機(jī)器人，隨著工業(yè)化的發(fā)展，尤其近十年以來(lái)，機(jī)器人的發(fā)展的應(yīng)用領(lǐng)域在不斷拓寬，目前一個(gè)很重要的特征，大家都知道，機(jī)器人已經(jīng)從
