Industrial Robots1.Manipulator overview of RobotsIt is the ancient robot in early appearance and developed on the basis of research into the middle of the twentieth century manipulator, along with the computer and automation technology development, especially the first digital electronic computer in 1946, since the advent of computer made amazing progress, to high speed, high capacity, low price direction. Meanwhile, the urgent demand of mass production of promoting automation technology progress, and for the development of robots laid a foundation. On the other hand, nuclear technology research requires certain operating machine instead of people handle the radioactive substances. In this one requirement background, the United States is developed in 1947, in 1948 and remote control robot developed mechanical master-slave manipulator.From the United States began developing manipulators first. In 1954 the United States first suggested the wear wal-mart, and the concept of industrial robot applied for patent. This patent point is using servo technology control of the robot joints, using an action on the robot hands, the robot can realize. Teaching movement recording and playback. This is the so-called demonstration emersion robot. The existing robots are using this kind of control mode. 1958 united control company developed the first manipulator riveting robot. As the earliest practical model robot products (demonstration reappearance) is 1962 U.S. AMF company launched "VERSTRAN" and UNIMATION company launched "UNIMATE". These industrial robot mainly by similar man's hands and arms who composed it can replace the hard labor in order to achieve production mechanization and automation, can in harmful environment operation to protect the personal safety and thus widely used in mechanical manufacturing, metallurgy, electronics, light industry and atomic energy and other departments.Industrial robot CaoZuoJi (by mechanical body), controller, servo drive system and detection sensor, making it a humanoid operation, automatic control, can repeat programming, can finish all kinds of assignments in 3d space the electromechanical integration automation production equipment. Particularly suitable for many varieties, change of flexible production batch. It to help stabilize, improve product quality, raise efficiency in production, improve working conditions and product rapid renewal plays an extremely important role.Robotic technology is integrated with computer, cybernetics, organization learning, information and sensing technology, artificial intelligence, bionics science and the formation of high technology and new technology, is a very active, contemporary study applied more and more widely. Robot applications, is a national industrial automation level of important symbol.Robot and not in the simple sense of labor, but replace artificial comprehensive people skills and machine a personification of the specialty of electronic machinery, already someone on the environment condition of rapid reaction and the analysis judgment ability, and a machine could be longer duration of work, high precision and the ability of resistance to bad environment, in a sense it is also machine process of evolution product, it is an important industrial and the industry production and service, but also set the advanced manufacturing technology field indispensable automation equipment.Manipulator is part of the action imitating the hands, according to the given program, track and demanding acquirement, handling or operation of the automatic mechanical device. In the industrial production of the application of industrial robots called "robot". Application of manipulator can be used to increase production level of automation production and labor productivity: can reduce laborintensity, assure product quality, achieve safety production; Especially in high temperature, high pressure, low temperature, low pressure and dust, explosive, toxic gases and radiation etc harsh environment, it instead of human normal work, meaning more significant. Therefore, in the mechanical processing, stamping, casting, forging, welding, heat treatment, electroplating, paint, assembly and light industry, transportation etc widely quoted are increasingly.The structure of the manipulator is simpler, specificity form began, strong for a machine tool's only feeder, and was attached to the machine's special manipulator. Along with the development of industrial technology, made by an independent program control realization repeated operation, suitable scope is wider "program control general manipulator", or general manipulator. Due to the change of general manipulator can quickly working procedures, good adaptability, so it continues to transform the medium and small batch production products gain extensive reference .posed of the manipulator1)ActuatorsHandNamely parts in contact with objects. Due to the different forms of contact with objects, can be divided into clamping type and adsorption the hands. Gripping type hand fingers (or by PAWS) and power transmission institution constitutes. Fingers are in direct contact with the object of components, common finger movement forms have moved back to the transformation of peace. Back to the transformation of simple structure, easy fingers, so application component manufacturing is widely applied translation type, its reason is less complicated structure, but translations type circular parts, fingers clamping workpiece diameter variation do not affect its axis position, therefore appropriate clamping diameter variation range workpiece.Finger structure by grasping object depends on surface shape, caught parts (the profile or within hole) and object weight and dimensions. Common refers to a flat, form the v-shaped finger and surface: the clip type and inside there supporting type; Index has double refers to type, by type and hands of double refers to type, etc.But the force transmission institution is produced by clamping force fingers to accomplish the task. Put objects clips Power transmission institutions are: the more commonly used type sliding channel, connecting lever lever type, bevel gear lever type, type, screw nut upper-and-lower, type spring type and gravity type, etc.Enclosed type hand made mainly by chuck, it is to rely on adsorption force (such as chuck formed in the negative pressure or an electric suction magnetic) adsorption objects, the corresponding adsorption hand have negative pressure and electric disk two kinds of suckers.For light small flake parts, smooth plate materials, usually with negative pressure chuch suck material. The way cause negative pressure air suction and vacuum pump type.To guide magnetic ring type and the plate with a hole, and have such parts of sheet etc (meshes, usually use electro-magnetic chuck suck material. The suction electro magnetic chuch by dc magnets and production. Communication electromagnet.With negative pressure chuch and electro magnetic chuch absorb charge, its shape, quantity, suckers absorbability size, according to adsorb object shape, size and weight size and decide.In addition, according to special needs, the hand and spoon type (such as casting manipulatorpoured bag part), Joe type (such as cold gear machine up-down material manipulator hand) type.WristHand and arm is connected components, and can be used to adjust the position by grasping object (i.e. posture).ArmThe arm is supporting caught objects, hand, an important part of the wrist. The arm's role is to drive to grab objects, and fingers predetermined asks its handling to the location specified. Industrial manipulator arm often moving parts by driving arm (such as oil cylinder, cylinders, rack-and pinion institutions, link mechanism, screw mechanism and CAM mechanism, etc.) and drive source (such as hydraulic and pneumatic or motor, etc.), in order to realize the combined arms all kinds of sports.The arm in telescopic or lifting movement, in order to prevent around its axis rotation, need a guide device, to ensure that the finger on the correct direction movement. In addition, orientation device can bear arms were bending moment and torsion moment when turning or arm movement in start-up, brake generated at the moment of inertia, make the moving parts stress state is simple.Orientation device structure form, commonly used are: single cylinder, double cylindrical, four cylinder and v-shaped chamfer, swallow tail trough etc oriented form.PillarPillar is supporting the arm parts, pillar also can be part of the arm and arm turn movement and lift (or pitch) movement are and pillar are closely linked. Manipulator to usually set for fixed, but need because of the job, sometimes also can make lateral movement, namely called will move a type bar.Walk InstitutionsWhen industrial robots need to complete a remote operation, or expanded use scope, the same seat installation roller, rail, etc, in order to realize the mobile mechanism of the machine movement. Industrial robots Roller type can be divided into the mobile mechanism of sounds and two trolley. Drive roller motion should be additional mechanical transmission device.BaseSeating is basic parts of manipulator, manipulator actuator components and the drive system are installed in on standby, so the role of the support and links.2)Drive systemDrive system is driving industrial robots actuators movement of the power unit, usually by power supply, the control adjusting device and auxiliary device component. The drive system used in hydraulic transmission, pneumatic transmission, power transmission and mechanical transmission etc 4 form..3)Control systemControl system is dominated by the requirements of industrial robots sport system. At present the control system of industrial robots by process control system and general electric positioning (or mechanical stop pieces positioning) systems. Control system has the electrical control and jet controltwo kinds, it dominates the manipulator procedures stipulated by the movement, according to people and memory of the manipulator instruction information (such as action sequence, trajectory, movement speed and time), and according to the control system of the information instruction executive agencies and, when necessary, the action of manipulator when motion surveillance, any error or fault alarm signal that..4)Position detection deviceControlling manipulator actuator position and keep movement of actuator actual position feedback to control system, and with setting the position to compare, and then adjusted by controlling system, thus make actuators to certain accuracy reached set position.3.Manipulator classificationThere are many kinds of industrial robots, about classification problems, at present in China, not unified classification standard in this temporary by use scope, drive mode and classify control system, etc.1)According to utility centRobots can be divided into special manipulator and general manipulator two:1.special manipulatorIt is attached to the host and have fixed program without independent control system mechanism. Special manipulator with action, less work object single, simple structure and reliable operation and cost low characteristic, suitable for big affiliate, such as automatic machine, automatic line and discharge of robot and 'processing center "the automatic automation production batch cutter replacement manipulator.2. general manipulatorIt is a kind of independent control system, program variable, action flexible manipulator. Through the adjustment may be used in different occasions, driving system and lattice performance range, its actions program is variable, the control system is independent. General manipulator work range, higher precision and versatility, applicable to the production of changing medium and small batch automation production.General manipulator according to the control can be divided into different ways of the positioning of the simple type and servo type two kinds: simple type with "opening and closing" type control positioning, can only be position control: servo type has servo system, can point position control system, also can achieve continuous control path control general servo model gm manipulator belong to nc type.2)According to the driving way points1. hydraulic transmission manipulatorBased on the hydraulic pressure to drive the actuators movement of the manipulator. Its main features are: catch weight of several hundred kg, stable transmission, compact structure, action quick. But for sealing device requirements, otherwise the oil leakage strictly to the working performance of the manipulator has a great influence, and not in work under high temperature, low temperature. If the manipulator by applying electro-hydraulic servo drive system, can achieve continuous trajectory control, make the manipulator, but universal expand electro-hydraulic servo valve manufacturingprecision, oil filter, strict cost are high.2. pneumatic theories.supported manipulator based on pressure of compressed air to drive the actuators movement of the manipulator. Its main features are: media sources is extremely convenient, output force is small, pneumatic action quick, simple structure, low cost. However, due to the air has compressible characteristics and work rate, the poor stability, and impact low air pressure, catch in commonly 30 kilograms heavy weight below, under the same conditions it caught the structure than hydraulic manipulator, so suitable for high-speed, light load, high temperature and dust big environment to work in.3. mechanical transmission manipulatorNamely the mechanical transmission (such as CAM, connecting rod, gear and rack, intermittent mechanism, etc) driven manipulators. It is a kind special the attached to work host manipulator, its power is passed by working machinery. Its main characteristic is accurate and reliable, action frequency motion, but structure is bigger, action program immutable. It is often used to work and discharge of host.4. power transmission manipulatorNamely, have special structure induction motors, linear motor or power step-motor direct driving actuators movement of the manipulator, because do not need the change in the middle, so the mechanical structure simple organization. One of the manipulator, the linear motor speed and longer journeys movement, maintaining and easy to use. Such manipulator is still small, but promising.3)According to the control mode points1. position controlIts movement for space between point-to-point control movement of mobile, only the position of several points in the process, unable to control its trajectory. If you would control points, you must increase more than the complexity of the electrical control system. Current use of special and general industrial robots are such.2. continuous trajectory controlIts trajectory of any continuous curve for the space, its characteristic is set point for unlimited, the whole mobile process under control, can achieve smooth and accurate movement, and use range, but the electrical control system is complicated. This kind of industrial robots generally USES small computer control.4.The application of industrial robots in production and its significanceBecause of its high flexibility and robot in life, manufacturing performance in various fields such as plays a very important role. It can carry goods, sort and products, and can in harmful environment to protect life safety operation, instead of man's heavy labor, so are widely used in machinery manufacturing, light industry and needs goods handling various places.In modern industry, the production process automation has become a prominent theme. The automation level from all walks of life becomes more and more high, modern processing workshop, often with manipulator to improve production efficiency, complete workers difficult to complete or dangerous job. Available in mechanical industry, processing, assembling and other production largely is not continuous. According to data is introduced, the American production in all industrial parts, 75percent is small batch production; Metal processing production batch of three-quarters under 50 pieces on the machine parts in real time accounted for only parts processing production time 5%. Here you can see, loading and unloading, handling, carrying the process such as the urgency of industrial robots mechanized for realizing these processes is automated and of generation. At present the finished work of manipulator are often used to have: injection industry from the mold to grab products and fast curing to the next will product production processes; Manipulator processing industry for picking, feeding; Casting industry for high temperature melting extracted liquid etc. Robots in automation workshop for transporting materials, engaged in welding, painting, assembling process operation, but will operate workers from onerous, drab, repeat liberated the manual labor. Especially in high temperature, dangerous or harmful work environment (radioactive, poisonous gas and dust, inflammable, explosive, strong noise, etc.), usable parts operation instead of manipulator. At present, the manipulator has been widely used in casting, forging, stamping, machining, paint, the assembly and so on various processes.In mechanical industry, the significance of application manipulator can be summarized as follows:1. To improve the production process of automationThe robot conducive to the realization of materials used, workpiece loading, unloading and transmit the cutter replacement and machine assembly etc, thus the automation degree can improve labor productivity and reduce production cost.2. To improve working conditions, and avoid personal accidentIn high temperature, high pressure, low temperature, low pressure and dust, noise and smell, or radioactive or have other toxic pollution and working space in the occasion of narrow choose and employ persons is dangerous hands direct operation or impossible, and the use of robots can part or all of the replace man safe working conditions, make homework improves.In some simple, repetitive, especially a heavy operation to replace man, robot can avoid due to negligence operating fatigue or accidents.3. Can relieve human, and facilitate the rhythmic productionInstead of people applied manipulator work, it is the one aspect of the direct reduce manpower, and because the application can be continuous work, robot is to reduce the human and another side. Therefore, the comprehensive processing in automatic machine, automatic line now barely manipulator, to reduce the manpower and the more accurate control production beat, facilitate rhythmic work on production.To sum up, the effective application of mechanical industry development manipulator, is an inevitable trend.。

机械手外文翻译ManipulatorAlong with our country the rapid development of industrial production, rapidly improve degree of automation, implementation artifacts of handling, steering, transmission or toil for welding gun, spray gun, spanner and other tools for processing, assembly operations such as automation, should cause the attention of people more and more.Manipulator is to imitate the people part of the action, according to agiven program, track and demanding acquirement, handling or operation ofthe automatic device. Applied in the industrial production of the manipulatoris referred to as \manipulator\Application manipulator can improve the automation of production water in production and labor productivity; Canreduce labor fatigue strength, to ensure product quality, implement safety production; Especially in high temperature and high pressure, low temperature, low pressure, dust, explosive, toxic and radioactive gases such as harsh environment, it instead of people normal work, the more significant. Therefore, in the machining, casting, welding, heat treatment, electroplating, spray painting, assembly, and light industry, transportation industry get more and more extensive application, etc.Manipulator institutional form is simple, strong professionalism, only asa loading device for a machine tools, special-purpose manipulator isattached to this machine. Along with the development of industrial technology, produced independently according to the process control to achieve repetitive operation, using range is wide \control generalmanipulator\hereinafter referred to as general manipulator. Generalmanipulator used to quickly change the working procedure, adaptability is stronger, so he is in constant transformation in the medium and small batch production of products are widely used.Manipulator is a kind of can automatic positioning control and can changeto programming with multifunctional machine, it has more degrees of freedom, can be used to move things to complete the work in different environments. InChina the low level of wages, plastic products industry still belongs to the labor-intensive, the use of the manipulator has become more popular. The electronic and automobile industry in Europe and the United States multinational companies very early in their factories in China introduced automatic production. But now the change is the industrial intensive distribution in south China, east China's coastal regions local plastic processing plant also began to manipulator show more and more interest, because they have to face high worker turnover rate, as as the challengewell s brought about by the workers pay inductrial injury fee.一、The composition of the manipulatorManipulator is in the form of a variety of, some relatively simple,some more complex, but the basic form is the same, generally by the actuators, transmission system, control system and the auxiliary device. 1. The actuator manipulator actuators, by the hand, wrist, arm, pillars. Hand is grasping mechanism, which is used to clamp and release artifacts, as a human finger, can complete staff of similar action. Is connected to the fingers and wrist arm components, can be up and down, left and right sides and rotary movement. Simple manipulator can not the wrist. Prop used to support the arm, can also according to need to make it move. 2. The driving system movement of the actuator by the transmission system to achieve. Common mechanical transmission system of mechanical transmission, hydraulic transmission, pneumatic transmission and power transmission etc. Several forms.3. The control system of manipulator control system main function is to control the manipulator according to certain procedures, movement direction, position, speed, simple manipulator is generally not set special control system, only the stroke switch, relay, control valves and control circuit can realize dynamic transmission system, the executing agency action in accordance with requirements. Action complex manipulator should adopts the programmable controller, microcomputer control. 二、classification and characteristics of the manipulatorRobots generally fall into three categories the first is generalmanipulator doesn't need manual operation. It is a kind of independence is not attached to a host device. It can according to the need of the task program, the operation of the provisions to complete. It is with the characteristics of common mechanical performance, also has general machinery,memory, intelligence of three yuan. The second is the need to do manually. Called Operating machine. It originated in the atom, military industry, first by Operating machine to complete a specific assignment, later to use radio signal Operating machine to explore the moon and so on. Used in the forging industry Operating machine falls under this category. The third kind is to use special manipulator, mainly attached to automatic machine or automatic line, used to solve machine tool material and workpiece to send up and down. This manipulator in a foreign country is called \host, driven by the host; Except a few working procedures generally is fixed, so it is special.三、The application of industrial manipulatorManipulator is in the process of mechanization, automation production, developed a kind of new type of device.

This manipulator was installed into ourmobile robot to constitute a remote rescue robot. The Denavit-Hartenberg method was used to establish the kinematic models and the path planning of the manipulator was researched. The operator could remote control the manipulator by the interactive interface of PCwhich could display moving picture and various data of the manipulator. The servos of the manipulator were controlled by the slave FPGA controller. In addition, the slave FPGA controller communicated withthe PC via the wireless communication module. Owing to the embedded Nios II program and IP (Intellectual Property) core generating PWM waves in FPGA, the system could control the multiple servos fast and flexible. In order to achieve real-time operation and simulation, the interactive interface was established by the mixed programming of VC and MATLAB.Key Words: The manipulator; Remote control; Denavit-Hartenberg; FPGA; Human-computer interaction1 IntroductionWith the development of the microelectronic technique and the computer technology, the manipulator has become essential equipment in the manufacturing industry. As we all known, the manipulator isusually applied to accomplish dull, onerous and repeated physical work, especially used to substitute the manual operation under the dangerous and the hazardous environment such as the corrosion and the high temperature.In this paper, the manipulator was installed our mobile robot. The tele-operation system of this manipulator was designed. The whole system is onstituted by PC and slave FPGA. The operator can remote control the manipulator by PC. The wireless communication was used for transmitting data between PC and FPGA. FPGA is controller of the the manipulator in the mobile robot. FPGA has the abundant internal resource and IP cores. And a central control option was built via an embedded Nios II program and an IP core in FPGA. Furthermore, Verilog language was adopted to design the IP core which generated digital PWM waves for controlling the manipulator. Therefore, this system could reach higher precision and easy to debug.MATLAB software was adopted to build the kinematic models of manipulator. And using D-H (the acronym of Denavit-Hartenberg) method to solve the forward and inverse kinematic equations of the manipulator, to analyze the motivation, to plan and track themotion’s path.In addition, a good interface of human-computer interaction was enhanced in the remote control system of the manipulator in PC. Moreover, the manipulator simulation technology was built by using the mixed programming of VC and MATLAB. Thus, the motion choreographs was got quickly and easily, also greatly saved time and cut the cost.2 Manipulator Model and Path PlanningAt first, the motion model of the manipulator was built. Then, the kinematic simulation and its path planning were researched. These works provided the foundation for the design of the remote control system of the manipulator.Motion Model of the ManipulatorThe manipulator was regarded as an open loop kinematic chain. It was constituted by five rotary joints. And its one end was fixed on a base while the other end was used to achieve the ability of grabbing. Therefore, it is better to establish a chain coordinate frame as shown in . The terminal position and attitude was determined via usingforward kinematic equation after knowing the rotating angle of every joint. The D-H parameter table shown as Table 1 was established by using the frames in .Coordinate frames of mechanical armTable 1 D-H Parameters of the Robot ArmDue to D-H method:T =T T +1T +1T =(TT T +1−TT T +1TT T +1TT T TT T +1TT T 0T T −TT T −TT T T T +1TT T +1TT T TT T +1TT T 00TT T TT T T T +101)Where C T T +1=cos T T +1 , S T T +1=sin T T +1 , C T T =cos T T , S T T =sin T T . The transformation matrix of every joint was given byequation (2).T 10=(cos T 1sin T 1sin T 1cos T 1000000001001) T 21=(cos T 2−sin T 200001T 1−sin T 2−cos T 2000001) T 32=(cos T 3−sin T 3sin T 3cos T 3000000001T 201) T 43=(cos T 4−sin T 40000−1−T 3sin T 4cos T 4000001) T 54=(cos T 5−sin T 5sin T 5cos T 5000000001T 401) T 50=(T T T T T T T T T T T T T T T T T T T T 00T T T T 01)=T 10T 2∗1T 3∗2T 4∗3T 5∗4 (2)Where unit vector T →,T →,T → in equation (2) was T→=TTTTTT , T →=TTTTTTTTTTT , T →=TTTTTTTT , T→=TTTTTTTT . Parameters of mechanical arm were given by T 1=85mm , T 2=116mm , T 3=85mm , T 4=95mm . Therefore the forward kinematicequation was determined by taking every parameter in equation (3).T 50=(180TT 1T (T 2+T 3)+116TT 1TT 2180TT 1T (T 2+T 3)+116TT 1TT 285+116TT 2+180T (T 2+T 3)) (3)In practical application, the manipulator was adopted to grabobjects. This required that the fixed position was given from terminalto target location. That was the inverse kinematic analysis ofmanipulator. Inverse transformation was used to determine angle of every rotary joint toward the established coordinates. And the used method of inverse transformation was the common method to solve such problem (this method also known as algebraic method).Using inversetransformation T T T −1−1separately to the left multiplication withT =50T 10T 2∗1T 3∗2T 4∗3T 5∗4 , the angle of every rotary joint (T 1 T 2 T 3 T 4 T 5)was determined. Owing to these results, the rotary angles (T 1T 2T 3)at terminal position of manipulator were totally decided by the target position [T T T T T T ]. Angle T 4 was used to change terminal attitude of the manipulator and it was changed by the known normal vector. However, angle T 5, was decided by the size of target object.Motion Simulation of the ManipulatorThe manipulator model was built and simulated via MATLAB toolbox. We could verify the rationality of the mathematical model. While the MATLAB model was established by table 1 and shown asMATLAB simulation of the manipulatorComparing to the and , the simulation model of the manipulator was coincided to the reference frame model. That was to say, the given coordinate frame was correct. These results also could be proved by the determined inverse kinematic equations via MATLAB shown in the table (2) and table (3).The target position was solved by forward kinematics. After that, the rotary angles were calculated by inverse kinematical equation. It turned out that these rotary angles coincided to the given angles. Therefore, these results verified the correctness of forward and inverse kinematical equation.Table (2) Forward Kinematics AnalyzeTable (3) Inverse Kinematics Analyze3 Path Planning of the ManipulatorThe total displacement of joint was calculated by inversekinematical equation when the manipulator moved to new position. Thus, the manipulator could move to new position. Although the manipulator finally moved to the expected position in such condition, the motion of the manipulator between these two points was unknown. Due to space limitations, motion and some certain position requirements, the manipulator was often unable to move as the above mentioned method. Therefore, the motion path was designed to coincide with the limited conditions.In this paper, we could use these certain limitations to decide some expected points. And these expected points were used to match the planning path of the manipulator’s movement. Owing to the planning path, coordinate in every part could be calculated. The rotary angleof every joint was calculated via inverse kinetical equation and these angles realized the movement of planning path. Movement of the manipulator was shown in (Where‘’ represented the points would be p assed by the manipulator;‘*’represented the expected points of every segment; ‘-’represented path planning of the manipulator). In , we could seethat the motion of the manipulator passed every planning point and the movement path coincided to the planning path.The path planning simulation of the manipulator4 Remote Control System of the Manipulato rThe remote control system of the manipulator contains the main PC and the slave FPGA controller using DE2 Board of ALTER Company. The motors of the manipulator were controlled by multipath PWM waves. And the PWM waves were generated by IP core. The FPGA controller Communicated with PC via wireless serial port. While in the PC interaction, the operator could observe the move of the manipulator in real-time and tele-control the motion of the manipulator. Also every movement of manipulator could be observed in advance via thesimulation technique. The general design of the manipulator remote control system was shown in .The block diagram of the remote control systemControl Mode of the ManipulatorThere were two control modes of the manipulator. One mode is thatthe inverse kinematical equations are calculated by FPGA straightly to determine angle of every rotary joint. Thus, the control of the manipulator was achieved. The advantage of this mode is more direct and independent to finish the control of the manipulator without the external devices. At the same time, this mode has large quantities of calculations, which occupy more internal storage and running time of FPGA. Resources of FPGA are wasted under this mode.The other mode accomplished the control of the manipulator by using VC and MATLAB in PC. Using VC and MATLAB finished a large number of complex calculations and determined angle of every rotary joint. And the angle results were transmitted to FPGA in order to accomplish the control of the manipulator. This manner saved lots of internal storage and running time. In addition, FPGA could finish other works underthis mode. But the manipulator was not under fast control in this mode.In this system, a new mode was adopted in the manipulator remote control system depending on the advantages of the two modes. Specifically, when the manipulator accomplished the specified and repeated movement the former mode was adopted under direct control by FPGA. When the manipulator wanted to achieve new motions the latter mode was used to be commanded by orders from PC. This new mode was made good use of advantages of the two modes in the above. And this new mode lightened computational burden and improved workingefficiency of the manipulator.SOPC Design for the Remote Control SystemMovement of the manipulator was controlled by servos. And the servos were controlled by PWM waves with the cycle of 20ms. Pulse width of these PWM waves was ~ corresponding to the rotary angle of servo with-90 degree to 90 degree. High precision of PWM waves were generated by IP core via Verilog in this system. The results were shown in . PWM waves controlled rotary angles of the servos via the servo drivers.The PWM IP coreMultiple of IP cores were able to be downloaded into FPGA. Andmultiple PWM waves with high precision were generated in the output. As shown in , the pulse width of these waves could be settled byprogram of Nios II. The movement of the manipulator was more flexible and in higher precision in this system.The IP cores generating PWM waveThe movement of the manipulator was accomplished by the duty ratio of PWM waves. Formula (4) inverted rotary angle T T to thecorresponding amount of the duty ratio of PWM waves. The duty ratio of PWM waves corresponded to the Nios II output.TTT T =1000000−(T T ∗50000+75000) (4) Wireless serial of 9600 baud rate was used to transmit thecoordinate and the angle information from host computer to FPGA. After that, the data and orders were analyzed by FPGA Then FPGA transmitted the movement results to interactive interface of host computer via wireless transition model. This communication was realized through adding UVRT communication protocol to FPGA.The Interactive Interface of the Remote Control SystemThe interactive interface of the remote control system was shown in . There were some functions in the interactive interface: videoobservation, the manipulator control and the simulation modeling. At first, the manipulator video could be seen from camera tointeractive interface. The operator could monitor the manipulator in real-time.Secondly, the angle and the coordinate could be set in control zone of the interactive interface. The angle of the manipulator could beset independently to each single joint. In addition, the angle settingcould be shown in real-time in the list of interactive interface (as shown in . In the set of coordinates, judging of coordinate setting assured that the total coordinates could achieve to the target points. Thus the manipulator could be controlled to move in the settled path depend on the angle information.Lastly, the MATLAB robot toolbox was embedded into this interactive interface. One interface was integrated both the control andsimulation of the manipulator. MATLAB robot toolbox was directly used by interactive interface in the manipulator modeling. Each group of information was simulated separately in order to detect whether each movement was correct. And the general simulation could test whether movement arrangement of the manipulator was reasonable. Combining with multiple simulation methods made the movement arrangement more flexible, the operation of the manipulator simpler and interface interaction more perfect.The interactive interface of the manipulator5 Experiment and SimulationIn order to verify properties of the remote control system of the manipulator, experiments of the system were under way and were comparing to the simulation system. To be specific, manipulator modeling was built by interactive interface and a group of coordinates could be designed. we could see that the manipulator modeling and control of the interactive interface design comforted to the design requirement. The comparing between experiment and simulation was shown in .The experiment and the simulation6 ConclusionIn the experiment, the 5-DOF manipulator modeling was simulated by MATLAB. In the slave FPGA board, control of the manipulator was accomplished via IP core based on the Verilog language. That greatly reduced design of the peripheral circuit, cut the cost, improved the precision and made the movement smoother without shaking. While in theinteractive interface, the mixed programming method of VC and MATLAB was embedded into the MATLAB simulation function. Thus the operability of this manipulator was enhanced. The system had a good ability of interactive interface. The whole system was verified and achieved to the expected effect. One new thing in this system was that embedded the MATLAB robot toolbox in the interactive interface. The D-H modeling, path planning and tele-operation and so on were accomplished by using this interactive interface directly. Compared to the other development tools, this interactive interface had portability, good compatibility, short development cycle and simple operation. References[1] Saeed B.
