9、 or the overall worksite. In teleoperating a remote robot,multiple viewpoints are necessary for operator to get sufficient situation awareness.</p><p> Situation awareness need enough information from the r
10、obot. And to control the robot, the order must be transmit to the robot by a remote way. Many systems used the computer card to do this work. In these kind of system, the main computer must deal with much information in
11、the information transmit task. </p><p> In this paper, we use a kind of RF chip to configure the information transmit task.This paper is organized as follows. In section 2 we describe developed mobile robot
12、 BCAR-01. Section 3 presents the control structure and the remote cockpit for it.Section 4 provides the method to organize the hardware of the communication card. Section 5 described the software of the system. The exper
13、iment and the conclusion are given in section 6 and 7 respectively.</p><p> II. THE MOBILE ROBOT BCAR-01</p><p> Mobile robot “BCAR-01” (figure 1) is designed for security scout, building insp
14、ection etc.. Especially, in a building which is danger but not has been destroyed,the robot can complete the searching work instead of human. By the sensors system in the robot, the environment information like temperatu
15、re or humidity could be collected [15-16].</p><p> Two driving wheels are driven by DC motors respectively which are symmetrically equipped on the underpan. Anothertwo supporting wheels are installed perpen
16、dicular to the driving wheels axis to keep the body balance in level. The total weight with a pile is 32kg. The maxim speed is 2m/s. With full charged batteries, the robot can work for about 2 hours incessantly. The moto
17、rs power is 180W, so the robot can load about 40kg.</p><p> Main parameters of the robot are shown in the table1.</p><p><b> TABLE 1</b></p><p> Type PARAMETERS of Ro
18、bot</p><p> With the deeply research, we changed the control system of the mobile robot. Now, a PC104 computer is used as control center. All the control command and sensor information in the system are dis
19、posed in this computer. Four kinds of hardware module are equipped in the PC104 computer to execute the control and detecting work. Firstly,DC motor control system is built in the control center computer. Two wheels of t
20、he robot with swing arm are driven by these DC motors. Secondly, two cameras with cont</p><p> Fig.1 Control system for the mobile robot</p><p> By the difference wheel speed control, the robo
21、t can swerve in origin or in a certain radius. The kinematics model of the robot is shown in figure 2.</p><p> Fig.2 Kinematics model of the mobile robot “BCAR-01”.</p><p> We define S1 and S2
22、 as the velocity of two wheels. In the single swerve status, the two wheels velocity could satisfy with the equation followed:</p><p><b> (1)</b></p><p> Here r denotes the distanc
23、e between the two wheels. And R is the swerve radius. In a certain time, the robot turn angle in certain direction by the difference velocity. The equation could be changed as:</p><p><b> (2)</b>
24、;</p><p> In (2), r is constant, which is 255mm in this robot. The ngle velocity of the robot could be expressed as:</p><p><b> (3)</b></p><p> From the (2) and (3),
25、we can conclude that to control the robot turn angel with the radius R could be gotten by the appropriate proportion between the two wheels difference velocity. But as the slipping error and other reason, the actual num
26、erical value for control should be adjusted real time.</p><p> III. THE TELEOPERATION SYSTEM FOR MOBILE </p><p> ROBOT BCAR-01</p><p> The robot teleoperation system consisted of
27、 control master, communication channel and robot system. Operator,joystick with force feedback and portable computer constitute the control master. Communication channel include the wireless network AP, master side netwo
28、rk card, slave side network card, embed communication server and video server.The robots are made up of carrier system, controller and navigation system, sensors and apperceive system.</p><p> Fig.3 Teleope
29、ration for the Mobile Robot</p><p> The whole system soft structure is Client/Server structure. Robot control computer is the Server. It wait for the command from the control master and control the DC motor
30、 etc. to finish the teleoperation instruction. Control master is the Client. All client which want to control the robot can send a request to ask for the robot server. So one robot can receive multiple control master com
31、mand, but the Server time should be distributed reasonably. Also, multi-robot can be controlled by the same op</p><p> In the master site, a cockpit with multiple kinds of interfaces is used. The operator c
32、an use the joystick or keyboard to input the commands. These commands information is coded and send to the robot. At the same time,the cockpit displays feedback information in different format.That is the GPS information
33、, gyro information etc. To reappear the situation information of the robot in the worksite, two kinds of telepresence system are adopted. Force telepresence is used to play the feedback informa</p><p> The
34、carrier system is a minitype mobile robot with four pedrail. Two cameras are equipped on the robot. One is for sensing, which has the small focus and widely visual field.Another is for task, which has a big focus, and na
35、rrowly visual field. These two cameras are used as the sensors of the robot. Mobile robot has been equipped with the distance sensor and force sensor as to apperceive the force feedback.</p><p> IV. HARDWAR
36、E OF THE WIRELESS SERIAL </p><p> COMMUNICATION CARD</p><p> As mentioned above, the motors are driven by the drivers which are controlled by the PC104 card computer. Another way is to transmi
37、t the orders by the wireless way but not direct hardware link. This kind of control style could improve the efficiency of the PC104 computer.</p><p> We use wireless transceiver systems as our hardware part
38、,which composed of the single chip and RF modules, that is,AT89S52 single chip and nRF2401.It contains four parts: RF modulesMCUInterface circuit and power supply part.</p><p> A. RF mod
39、ules</p><p> RF circuit system is composed of nRF2401 and a number of external components. As the following figure, it is mainly consisted of the amplifier, crystal oscillator and modulator.nRF external tra
40、nsceiver includes RF front-end ( the antenna matching network), and phase-locked loop PLL circuit (including crystal oscillators, VCO and loop filter circuit inductance). As the external components is the key elements to
41、 achieve the function of nRF 2401, the quality and accuracy of these components can dir</p><p> We use the reference circuit given by the Nord Company for the power of nRF2401. C5, C6 are the decoupled capa
42、citors. The antenna part of the reference circuit uses a horizontal antenna, so it occupies a larger space. But now, in the field of wireless communications, we often use inverted F antenna. Inverted F antenna is closer.
43、 The bandwidth is moderate and it is not easy to damage, but also it absorbs a smaller power compared with whip-type antenna. Therefore,in this design we use inverted F a</p><p> B. The design of the contro
44、l part of the single chip</p><p> The single chip communicates with the wireless communication module through the serial port in this system.After the wireless transceiver system received the data, it will
45、be transmitted to the single chip through the serial port. At the</p><p> same time, some other control command will be sent by the single chip. Similarly, at the time when the system sends data,the control
46、 command will be sent to the wireless communication module through the serial port by this single chip and then be sent out using the wireless communication module.</p><p> Fig.4 Configuration of the nRF240
47、1</p><p> Since nRF2401 uses DRI, CLK and DATA, the three wires to implement transmission and considering the factor of the rate, the connection of AT89S52 and nRF2401 will be implemented through the SPI in
48、terface. The external system will be set with FLASHRAM, Network Controller, LCD monitor, A/D Converter, single chip and so on. Within our design, as the single chip AT89S52 has not the SPI interface, we have to simulate
49、I/O to SPI. The operation for simulating SPI includes SCLK, data Input and Output. C</p><p> Fig.5 Chip information Transmission of the nRF2401 and AT89S52</p><p> C. The design of the power s
50、upply part</p><p> According to the power’s requirements of the wireless transceiver module NFR2401, we decide to choose ASM1117 to supply the power for 3.3V. The power supply of the system is composed of t
51、he power supply module, an integrated voltage regulator AMS1117 and a number of external components. AMS1117 is a DC-DC voltage converter; it can convert the 5V voltage to 3.3V voltage.</p><p> V. THE SOFTW
52、ARE PART OF WIRELESS TRANSCEIVER</p><p><b> MODULE</b></p><p> The part of the Wireless transceiver module should first initialize the AT89S52 and nRF2 401. The nRF2401’s initializ
53、ation includes the Transceiver Mode of the RF Modules, transceiver channel frequency, the rate of the transfer, address, CRC Checksum, Chip transmission power and oscillators frequency configuration. In this design,chann
54、el 1 (Channel 1) mode is mainly used to transport data in the Shock Burst TM, the Data Rate is 240kbps, transceiver channel frequency is 2402 MHz, Crystal Frequenc</p><p> A. AT89S52 configures nRF2401</
55、p><p> Set CS high, CE low and enter the programming mode of nRF2401, the Data pin of nRF2401 is in the input state, the host writes the data through the MOSI and reads the data from MSIO, configuration data i

57、writes data through the MOSI and reads data from the MISO. Input the data through 2401 feet of RnF2401 to the TX FIOF, and set the CE low and start the burst transfer mode.</p><p> C. AT89S52 reads data fro
58、m nRF2401</p><p> When nRF2401 is under the receiving mode and has received the packet, the host writes data through the MOSI and read data from MISO. Because of the two resistors in the figure, the data wr
59、itten in the MOSI will not affect the data outputted from nRF2401.</p><p> VI. CONTROL ROBOT UNDER THE VIRTUAL SCENE</p><p> With the above analysis, we build the remotely control system for r
60、obot.In this robot system, we designed a wireless serial communication card to send or receive the information between the robot and the control center. The multiple control information are transferred by the special net
61、work. But finally they must be used in the robot control drivers. The next picture is the wireless serial communication card to transfer the data.</p><p> In the robot body , a wireless serial receive card
62、is used to receive the data from the robot. The next picture is about the card.</p><p> In the real control work, by a joystick, the desirable direction and angel value are easy to input to the system. In o
63、ur experiments we input the angle velocity θ / s in a fixed radius. Then the wheels speed could be calculated by (3). But</p><p> in narrow places, the radius should be changed little. At the same time, the
64、 wheel speed should be little. </p><p> We use a joystick, which is easy for human and the mobile robot, based on the man-machine engineering principal and the characteristic of the mobile robot and its man
65、ipulation.The operator grids the joystick, moves the joystick and draws the robot moving. The angle data are detected by the sensors equipped on the joystick, and communicated to the teleoperation system by wireless comm
66、unication card.</p><p> VII. CONCLUSION</p><p> For the purpose of remotely controlling mobile robot BCAR-01, we designed a teleoperation system with the following characters: a wireless seria
67、l communication card is used to transmit the information. Compared with the direct information transmission, the card could be used as atranslucent communication card which could improve the efficiency of the main contro

84、如下圖,它主要由放大器, 晶體振蕩器和調制器組成。nRF外部收發(fā)器包括射頻前端(天線匹配網絡),和鎖相環(huán)PLL電路(包括晶體振蕩器,壓控振蕩器和環(huán)路濾波電路電感)。由于外部元件是實現nRF 2401功能的關鍵因素,這些部件的質量和準確性直接影響整體裝置的性能。</p><p> 我們使用諾德公司給出的給nRF2401供電的參考電路,C5、C6是解耦電容器。參考電路的天線部分采用水平天線,所以它占據了很大的空間,
85、但現在,在無線通信領域,我們經常用倒F天線,倒F天線是比較接近的,它的帶寬適度并且不易損壞,而且它吸納了相比whip-type天線較小的功率。因此,在這個設計中,我們使用圖5中的倒F天線。匹配網絡是由L1、L2,C3、C4、C9和C10組成。</p><p> 單片機控制部分的設計</p><p> 在這個系統(tǒng)中單片機通過串行端口和無線通信模塊通信,在無線收發(fā)系統(tǒng)后收到數據后,它將通過

87、LASHRAM,網絡控制器、液晶顯示器、A / D轉換器,,單片機等等。在我們的設計中,,因為單片機AT89S52沒有SPI接口, 我們必須模擬I / O轉換為SPI接口。模擬SPI操作包括SCLK、數據輸入和輸出。和標準SPI接口相比,nRF2401只有一DATA和SPI中的MISO和MOSI相對應。因此,這關系圖如圖5所示,。</p><p> 圖5,nRF2401和AT89S52的芯片信息傳輸</p
88、><p><b> 供電電源部分設計</b></p><p> 根據無線收發(fā)模塊NFR2401的電源要求,我們決定選擇ASM1117 來供3.3V電源,供電系統(tǒng)的供電模塊,一個完整的電壓調節(jié)器AMS1117和大量的外部元件組成。AMS1117是DC-DC電壓轉換器,它可以將 5V電壓轉換為3.3V電壓。</p><p> 5、無線收發(fā)模塊的軟
89、件部分</p><p> 無線收發(fā)模塊部分應該首先初始AT89S52和 nRF2401,nRF2401的初始化包括射頻模塊的收發(fā)模式,收發(fā)信道頻率,發(fā)送速率,地址,CRC校驗,芯片的傳輸功率和振蕩器頻率配置。在這個設計中,頻道1(1頻道)模式主要是用于在沖擊破裂TM中傳輸數據,數據率是240kbps,收發(fā)頻道頻率是2402MHZ,晶振頻率是16MHZ, -5d芯片頻電源是-5d Bm,現在我們談論nRF2401

91、52發(fā)送數據給nRF2401</p><p> 設定CE引腳位高電平并使nRF2401進入TX模式,nRF2401的數據針處于輸入狀態(tài),主機通過MOSI寫數據通并從MISO讀取數據,通過RnF2401 的2401引腳輸入數據給TX FIOF,設定CE為低電平并開始破裂傳輸模式。</p><p> C、89S52 從RF2401讀取數據</p><p> 當nR
92、F2401處于接收模式并已取得數據包,, 主機通過MOSI寫數據通并從MISO讀取數據,因為圖中的兩個電阻,寫入MOSI的數據不影響從nRF2401輸出的數據。</p><p> 6、在虛擬場景下控制機器人</p><p> 根據上述分析,我們建立了機器人遠程控制系統(tǒng)。在這個機器人系統(tǒng)中,我們設計了無線串行通信卡來在機器人與控制中心之間發(fā)送或接收信息。多重控制信息由特殊網絡的轉移。但最
93、終,他們必須被用在機器人控制驅動器中。接下來的照片是轉移數據的無線串行通信卡。</p><p> 在機器人體內,一個無線串口接收卡用來從機器人接收數據,接下來的圖片就是關于這張卡的。</p><p> 在真正的控制工作中,,通過操縱桿,輸入系統(tǒng)。理想的方向和角度值很容易地輸入系統(tǒng)中。在試驗中,我們在固定的半徑內輸入角速度,然后車輪速度可由公式(3)計算。但在狹窄的地方,半徑應沒有什么改
94、變。與此同時,車輪的轉速減小。</p><p> 我們使用的操縱桿,對于人和移動機器人是方便的, 是基于人機工程學的基本原理和移動機器人的特點及它的操作。控制者控制搖桿、移動操縱桿,使機器人移動。裝配于操縱桿的傳感器能探測到角度數據,并通過無線通訊卡和遙控制系統(tǒng)通信。</p><p><b> 7、總結</b></p><p> 為了遠程
