5、ardous to do routine and tedious assembly line jobs , or it can perform jobs that might be hazardous to the human worker . For example , one of the first industrial robots was used to replace the nuclear fuel rods in nuc

6、lear power plants . A human doing this job might be exposed to harmful amounts of radiati</p><p>　　The robot can be thought of as a machine that will move an end-of-arm tool , sensor , and gripper to a prepr

7、ogrammed location . When the robot arrives at this location , it will perform some sort of task . This task could be welding , sealing , machine loading , machine unloading , or a host of assembly jobs . Generally , this

8、 work can be accomplished without the involvement of a human being , except for programming and for turning the system on and off .</p><p>　　The basic terminology of robotic systems is introduced in the foll

9、owing : </p><p>　　1. A robot is a reprogrammable , multifunctional manipulator designed to move parts , materials , tools , or special devices through variable programmed motions for the performance of a var

10、iety of different task . This basic definition leads to other definitions , presented in the following paragraphs , that give a complete picture of a robotic system . </p><p>　　2. Preprogrammed locations ar

11、e paths that the robot must follow to accomplish work . At some of these locations , the robot will stop and perform some operation , such as assembly of parts , spray painting , or welding . These preprogrammed location

12、s are stored in the robot’s memory and are recalled later for continuous operation . Furthermore , these preprogrammed locations , as well as other program data , can be changed later as the work requirements change . Th

13、us , with regard to this progra</p><p>　　3. The manipulator is the arm of the robot . It allows the robot to bend , reach , and twist . This movement is provided by the manipulator’s axes , also called the d

14、egrees of freedom of the robot . A robot can have from 3 to 16 axes . The term degrees of freedom of freedom will always relate to the number of axes found on a robot .</p><p>　　4. The tooling and grippers a

15、re not part of the robotic system itself ; rather , they are attachments that fit on the end of the robot’s arm . These attachments connected to the end of the robot’s arm allow the robot to lift parts , spot-weld , pain

16、t , arc-weld , drill , deburr , and do a variety of tasks , depending on what is required of the robot .</p><p>　　5. The robotic system can also control the work cell of the operating robot . the work cell o

17、f the robot is the total environment in which the robot must perform its task . Included within this cell may be the controller , the robot manipulator , a work table , safety features , or a conveyor . All the equipment

18、 that is required in order for the robot to do its job is included in the work cell . In addition , signals from outside devices can communicate with the robot in order to tell the robot </p><p>　　The roboti

19、c system has three basic components : the manipulator , the controller , and the power source .</p><p>　　A . Manipulator </p><p>　　The manipulator , which does the physical work of the robotic s

20、ystem , consists of two sections : the mechanical section and the attached appendage . The manipulator also has a base to which the appendages are attached . Fig.1 illustrates the connection of the base and the appendag

21、e of a robot .</p><p>　　The base of the manipulator is usually fixed to the floor of the work area . Sometimes , though , the base may be movable . In this case , the base is attached to either a rail or a t

22、rack , allowing the manipulator to be moved from one location to another .</p><p>　　As mentioned previously , the appendage extends from the base of the robot . The appendage is the arm of the robot . It can

23、 be either a straight , movable arm or a jointed arm . the jointed arm is also known as an articulated arm .</p><p>　　The appendages of the robot manipulator give the manipulator its various axes of motion .

24、 These axes are attached to a fixed base , which , in turn , is secured to a mounting . This mounting ensures that the manipulator will remain in one location。</p><p>　　At the end of the arm , a wrist is co

25、nnected . The wrist is made up of additional axes and a wrist flange . The wrist flange allows the robot user to connect different tooling to the wrist for different jobs . </p><p>　　The manipulator’s axes a

26、llow it to perform work within a certain area . This area is called the work cell of the robot , and its size corresponds to the size of the manipulator . Fig.2 illustrates the work cell of a typical assembly robot . As

27、the robot’s physical size increases , the size of the work cell must also increase .</p><p>　　The movement of the manipulator is controlled by actuators , or drive systems . The actuators , or drive system ,

28、 allows the various axes to move within the work cell . The drive system can use electric , hydraulic , or pneumatic power . The energy developed by the drive system is converted to mechanical power by various mechanical

29、 drive systems .The drive systems are coupled through mechanical linkages .These linkages, in turn , drive the different axes of the robot . The mechanical linkages ma</p><p>　　B. Controller</p><p

30、>　　The controller in the robotic system is the heart of the operation. The controller stores preprogrammed information for later recall, control peripheral devices, and communicates with computers within the plant for

31、 constant updates in production </p><p>　　The controllers is used to control the robot manipulator’s movements as well as to control peripheral components within the work cell. The user can program the movem

32、ents of the manipulator into the controller through the use of a hand-held teach pendent. This information is stored in the memory of the controller for later recall. The controller stores all program data of the robotic

33、 system. It can store several different programs, and any of these programs can be edited.</p><p>　　The controller is also required to communicate with peripheral equipment within the work cell. For example,

34、 the controller has an input line that identifies when a machining operation is completed. When the machine cycle is completed, the input line turns on, telling the controller to position the manipulator so that it can p

35、ick up the finished part. Then, a new part is picked up by the manipulator and placed into the machine. Next, the controller signals the machine to start operation.</p><p>　　The controller can be made from m

36、echanically operated drums that step through a sequence of events. This type of controller operates with a very simple robotic system. The controllers found on the majority of robotic systems are more complex devices and

37、 represent state-of-the-art electronics. That is, they are microprocessor-operated. These microprocessors are either 8-bit, 16-bit, or 32-bit processors. This power allows the controller to be very flexible in its operat

38、ion.</p><p>　　The controller can send electric signals over communication lines that allow it to talk with the various axes of manipulator. This two-way communication between the robot manipulator and the co

39、ntroller maintains a constant update of the location and the operation of the system. The controller also controls any tooling placed on the end of the robot’s wrist. </p><p>　　The controller also has the jo

40、b of communicating with the different plant computers . The communication link establishes the robot as part of a computer-assisted manufacturing (CAM) system.</p><p>　　As the basic definition stated , the r

41、obot is a reprogrammable , multifunctional manipulator . Therefore , the controller must contain some type of memory storage . The microprocessor-based systems operate in conjunction with solid-state memory devices . The

42、se memory devices may be magnetic bubbles , random-access memory , floppy disks , or magnetic tape . Each memory storage device stores program information for later recall or for editing .</p><p>　　C. Senso

44、r interfance </p><p>　　This is the part for the user to operate a robot,i.e.,the control panel.</p><p>　　E. Manipulator base </p><p>　　A robot may work in a fixed base,or in a mobi

45、le base,that is ,it can move about by employing wheels or legs.</p><p>　　F. Power supply</p><p>　　The power supply is the unit that supplies power to the controller and the manipulator . Two ty

46、pes of power are delivered to the robotic system . One type of power is the AC power for operation of the controller . The other type of power is used for driving the various axes of the manipulator . For example , if th

47、e robot manipulator id controlled by hydraulic or pneumatic manipulator drives , control signals are sent to these devices , causing motion of the robot .</p><p>　　For each robotic system , power is required

48、 to operate the manipulator . This power can be developed from either a hydraulic power source , a pneumatic power source , or an electric power source , These power sources are part of the total components of the roboti

51、做重復(fù)繁雜的裝配線工作，或能做那些對于工人來說是危險的工作，例如：第一代工業(yè)機器人是用來在核電站中更換核燃料棒，如果人去做這項工作，將會遭受有害射線的輻射。工業(yè)機器人亦能工作在裝配線上將小元件裝配到一起，如將電子元件安放在電路印刷板，這樣，工人就能從這項乏味的常規(guī)工作中解放出來。機器人也能按程序要求用來拆除炸彈，輔助殘疾人，在社會的很多應(yīng)用場合下履行職能。</p><p>　　我們可以把機械人看成是將手臂末端的工

52、具、傳感器和手爪移動到程序指定位置的一種機器。當機器人到達位置后，它將執(zhí)行某種任務(wù)。這些任務(wù)可以是焊接、密封、機器裝料、拆裝以及裝配工作。除了編程以及系統(tǒng)的開停之外，一般來說這些工作可以在無人干預(yù)下完成。</p><p>　　如下敘述的是機器人系統(tǒng)基本術(shù)語：</p><p>　　1.機器人是一個可編程、多功能的機械手，通過給要完成的不同任務(wù)編制各種動作，它可以運動零件、材料、工具以及特殊裝

56、械手、控制器、傳感器、用戶界面、操作基座和動力源。</p><p><b>　　A．機械手</b></p><p>　　機械手做機器人系統(tǒng)中粗重工作，它包括兩個部分：機構(gòu)和附件,機械手也有聯(lián)接附件基座，如下圖所示一機器人基座與附件之間的聯(lián)接情況。</p><p>　　機械手基座通常固定在工作區(qū)域的地基上，有時基座也可以移動，在這種情況下基座安裝

57、在導(dǎo)軌或者軌道上，允許機械手從一個位置移動到另外一個位置。</p><p>　　正如前面所提到的那樣，附件從機器人基座上延伸出來，附件就是</p><p>　　機器人的手臂，它可以是直線型，也可以是軸節(jié)型手臂，軸節(jié)型手臂也是大家所知的關(guān)節(jié)型手臂。</p><p>　　機械臂使機械手產(chǎn)生各軸的運動。這些軸連在一個安裝基座上，然后再練到托架上，托架確保機械手停留在某一位

58、置。</p><p>　　在手臂的末端上，連接著手腕，手腕由輔助軸和手腕凸緣組成，手腕是讓機器人用戶在手腕凸緣上安裝不同工具來做不同種工作。</p><p>　　機器手的軸使機械手在某一區(qū)域內(nèi)執(zhí)行任務(wù)，我們將這個區(qū)域為機器人的工作單元，該區(qū)域的大小與機械手的尺寸相對應(yīng)，一個典型裝配機器人的工作單元。隨著機器人機械結(jié)構(gòu)尺寸的增加，工作單元的范圍也必須相應(yīng)增加。</p><

59、p>　　機械手的運動由執(zhí)行元件或驅(qū)動系統(tǒng)來控制。執(zhí)行元件或驅(qū)動系統(tǒng)允許各軸在工作單元內(nèi)運動。驅(qū)動系統(tǒng)可用電氣液壓和氣壓動力，驅(qū)動系統(tǒng)所產(chǎn)生的動力經(jīng)機構(gòu)轉(zhuǎn)變?yōu)闄C械能，驅(qū)動系統(tǒng)與機械傳動鏈相匹配。由鏈、齒輪和滾珠絲杠組成的機械傳動鏈驅(qū)動著機器人的各軸。</p><p><b>　　B.控制器</b></p><p>　　機器人控制器是工作單元的核心?？刂破鲀Υ嬷A(yù)編
