Operation Scenario

Diagram below shows the typical operation scenario. The Jaguar is a wireless networked outdoor mobile robot. It comes with a wireless 802.11 AP/router. The remote host controller PC running the “Jaguar Control” program connects to the Jaguar robot via:

 Network cable – Connect the robot on-board AP/router. (DO NOT connect to the WAN port), or  Wireless – To connect the host controller PC to the on-robot wireless AP/router, configure the host PC’s

wireless settings using the default wireless configuration settings found in the Network Connection session of this manual.

Human operator carrying the host controller PC could use the head-mounted display (accessory option) and the included game-pad controller in outdoor environment to monitor and control the operator under any outdoor lighting environment, even under direct sunshine. The included Jaguar control program will therefore be projected on the head-mounted display, where you could see all the sensor information from the robot, and the video streamed from the camera on robot (Please refer to “Jaguar control program” session for detail).

(Optional)

Gamepad Controller

Portable PC (Host controller PC)

(Optional)

Typical Operation Scenario

Note: The host controller PC running the “Jaguar Control” program could be mounted on the robot instead off the robot if your application requires so.

Software Installation

Jaguar Control programs, application development library and supporting documents could be found from the Jaguar software CD.

On the host controller computer, you should install the following programs from the installation CD:

 “Jaguar Control” program - installed by the Setup.exe from CD  Google Earth program - could be downloaded from http://earth.google.com/download-

earth.html. Please follow its installation instruction.

III. Operation of Jaguar Robot

End user could develop his own Jaguar control program using the supplied development API and tools. Here, we are going to discuss how to control the robot using the included “Jaguar Control Program” (You need to install Google Earth program first).

Using Dr Robot Jaguar Control Program

This program will demonstrate how to control to navigate the Jaguar, move the arm-tracks and how to interpret, process, display and log multi-sensor information.

This program provided with source code (c#)

 updates motor encoder reading, motor temperature, board voltage and battery voltage measuring

at 10Hz;

 reads and displays IMU and Laser Range sensor data;  displays GPS reading on the Google Earth;  displays and controls Axis camera.

Once you start the program, you will see the “Login Window”

It will read all the configuration information from outdoorrobotconfig.xml in c:\DrRobotAppFile\.

When “Connect Robot” is clicked, it will start the WiRobotGateway program (also in c:\DrRobotAppFile\) and try connecting to the Robot.

Google Earth is then loaded and it may take a while.

Google Earth supports offline use (without Internet), but you have to obtain the map online ahead of use.

When Internet is not presented, this loading process will take a longer time for trying to connect with Google Earth website. You will not get the correct Latitude and Longitude position by mouse clicking on map before the map loading is finished. When loaded, click “OK” button.

- 9 -

www.DrRobot.com

“FlyToSetPoint” button will bring you to the location (latitude/longitude) specified in outdoorrobotconfig.xml. This is the location you would like the map to center and show around. You should modify this location according to your location. This could be done by inputting the value in this xml file or navigating on Google Earth map to your interested point, then clicking “SaveSetPoint” button. The location value of the map center will then be saved to the outdoorrobotconfig.xml when program is closing.

- 10 -

www.DrRobot.com

You could use the vertical track bar to zoom in or out.

(

p

When the GPS-IMU module is presented, this program will connect and display the GPS information on Google Earth and IMU raw data on the 6 chart boxes.

When camera is presented, the video and Av control buttons will be show in the video window.

You could use the included Game pad controller to navigate the robot. When used outdoor, especially under direct sun lights, head-mounted display (optional accessory) will provide clear and large display for excellent outdoor experience.

Note: when using Gamepad control, you need to make sure the program window is in “focus”.

Initializing or resetting arm-track position:

After power up, or when the actual arm position is different from the diagram below, you should reset the arm-track position as following:

 drive the arm forward and being flat on the ground, we call this initial or “0”

position (extend forward)

www.DrRobot.com

- 11 -

 then, click the “Set arm’s initial position” button to save this value and reset arm position display.

Clicking

button, you will display laser scanner data in polar view as shown below.

Battery information and motor information will be displayed in window below:

If the robot uses the included Li-Po battery, you need to stop the robot when voltage is below marked voltage (22.2V) to protect battery. Motor temperatures are also displayed in the display. PWM boxes show the PWM values received in motor driver board from motion control board.

The two horizontal track bars show the gamepad left and right stick control value.

You could record raw GPS-IMU/Encoder sensor data by clicking

button. The raw file will be saved

under current execution folder with file name GPSIMURec*.txt.

All traces are displayed on Google Earth by KML data. Since the current version of Google Earth does not provide programming method to clear these KML data, there is risk of memory leak. You could manually clear these KML data by: right-clicking on “Temporary Places”, then choosing “Delete Contents”. (That is why we did not hide Google Earth program)

On normal program exit, Google Earth will be closed. However, you should double check it using “Windows Task Manager”, or you may not be able to display Google Earth when you start Jaguar control program again.

DRROBOTSentinelCONTROL.OCX: Please refer to “WiRobot SDK API Reference Manual.pdf” for

detail.

2.

WiRobotGateway.exe

3. AXIS Media Control Library Set These are the camera control component for the AXIS Mini Camera

(P/N: AXCAM) used for Jaguar robot. Please refer to “AXIS Media Control SDK Help” for detail.

- 19 -

www.DrRobot.com

Motion Control/Sensing System:

Jaguar comes with a special version of PMS5005 as its motion control and sensing board. It follows the Dr Robot WiRobotSDK protocol and user could control and access Jaguar by Dr Robot ActiveX control (DrRobotSentinelActivexControl.ocx) and WiRobot gateway program.

Based on the protocol, you can develop your own program on any system. You could request protocol sample code from Dr Robot using C++/Java. You should contact Dr Robot with any questions regarding SDK API and protocol.

The communication port is connected at WiFi module-I port 1.

Gateway program will connect to this board at 192.168.0.60, port 10001.

Here is C# sample code to control Jaguar System with ActiveX control, myJaguar is DrRobotSentinelActiveXControl.

Arm Motor control: By default the system provides synchronized control, so the left/right arm motors only use channel 0 PWM signal, but you can get each encoder reading for left arm and right arm.

private void myJaguar_MotorSensorEvent(object sender, EventArgs e)

{

//here reads back PWM value for all motors

leftArmMotor.pwmOutput = myJaguar.GetMotorPWMValue1(); rightArmMotor.pwmOutput = myJaguar.GetMotorPWMValue1(); //right motor still uses PWM channel 0 leftWheelMotor.pwmOutput = myJaguar.GetMotorPWMValue4(); rightWheelMotor.pwmOutput = myJaguar.GetMotorPWMValue5();

leftArmMotor.encoderDir = myJaguar.GetEncoderDir1(); leftArmMotor.encoderPos = myJaguar.GetEncoderPulse1(); leftArmMotor.encodeSpeed = myJaguar.GetEncoderSpeed1();

rightArmMotor.encoderDir = myJaguar.GetEncoderDir2(); rightArmMotor.encoderPos = myJaguar.GetEncoderPulse2(); rightArmMotor.encodeSpeed = myJaguar.GetEncoderSpeed2(); }

You can read board voltage(5V) and battery voltage in standard sensor Event.

private void myJaguar_StandardSensorEvent(object sender, EventArgs e)

{ boardVol = ((double) myJaguar.GetSensorBatteryAD1() / 4095 * 9); motVol = ((double) myJaguar.GetSensorBatteryAD2() / 4095 *

33.749);

}

You can read motor temperature sensor in custom sensor event, function Trans2Temperature() is based on the sensor specification to translate AD value to temperature celcius degree.

Also you can read left/right wheel motor encoder in this event.

private void myJaguar_CustomSensorEvent(object sender, EventArgs e)

{

//here can read back left wheel motor and right wheel motor encoder information

leftWheelMotor.encoderPos = myJaguar.GetEncoderPulse4(); leftWheelMotor.encodeSpeed = myJaguar.GetEncoderSpeed4();

- 20 -

www.DrRobot.com

leftWheelMotor.encoderDir = myJaguar.GetEncoderDir4();

rightWheelMotor.encoderPos = myJaguar.GetEncoderPulse5(); rightWheelMotor.encodeSpeed = myJaguar.GetEncoderSpeed5(); rightWheelMotor.encoderDir = myJaguar.GetEncoderDir5();

//temperature sensor here

RightArmMotorTemp = Trans2Temperature((double)myJaguar.GetCustomAD7()); leftArmMotorTemp = Trans2Temperature((double)myJaguar.GetCustomAD5()); leftWheelTemp = Trans2Temperature((double)myJaguar.GetCustomAD6());

rightWheelTemp = Trans2Temperature((double)myJaguar.GetCustomAD8()); } NOCONTROL = -32768;

To stop all motor, you could use:

myJaguar.DcMotorPwmNonTimeCtrAll(16384, 16384, 16384, 16384, 16384,

16384);

To control track/arm motor using PWM control with value 32767 (full PWM) you could use:

myJaguar.DcMotorPwmNonTimeCtrAll(32767,NOCONTROL, NOCONTROL, NOCONTROL, NOCONTROL, NOCONTROL);

or

myJaguar.DcMotorPwmNonTimeCtr(0,32767);

Using position control, move motor to encoder position 2000 in 2000 ms, you could use:

myJaguar.DcMotorPositionTimeCtrAll(2000,NOCONTROl,NOCONTROL,NOCONTROL,N OCONTROL, NOCONTROL, 2000);

or

myJaguar.DcMotorPositionTimeCtr(0, 2000, 2000);

Using velocity control, move motor at encoder speed 200, you could use:

myJaguar.DcMotorVelocityNonTimeCtrAll(200,NOCONTROL,NOCONTROL,NOCONTROL ,NOCONTROL,NOCONTROL);

or

myJaguar.DcMotorVelocityNonTimeCtr(0,200);

Same for the track/wheel motor control, the left track/wheel motor is at PWM channel 3, right track/wheel motor is at PWM channel 4.

To control head lights, using expanded IO port bit7.

Turn off light:

myJaguar.SetCustomDOUT(expandedIO & 0x7f);

Turn on light: myJaguar.SetCustomDOUT(expandedIO | 0x80);

Software watchdog: The system will auto stop all the motors if it does not received any data package in 5 second.

Laser Ranger sensor (4m version, URG-04LX) is connected to WiFi module–1 port 2 after voltage level conversion. You could access the sensor data via TCP socket at port 10002 with IP 192.168.0.60.

Default settings for the serial port are: 115200, 8, N, 1, no flow control, TCP, port number 10002

Date and communication protocol could be found in “URG-04LX commspec_eg.pdf”.

GPS

GPS sensor output interface is RS232 serial port, and connected to WiFi module-2 port 2 after voltage level conversion. You could access the sensor data via TCP socket at port 10002 with IP 192.168.0.61.

Default settings for the serial port are: 115200, 8, N, 1, no flow control, TCP, port number 10002

NMEA 0183 sentence is described in file “GPS18x_TechnicalSpecifications.pdf”. GPS configuration tool is SNSRXCFG_200.exe

9DOF IMU (Gyro/Accelerometer/Compass)

The output interface for this IMU sensor module is serial port. It is connected to WiFi module-2 port 2. You could read from this sensor via TCP port 10001 at IP 192.168.0.61. Serial Port Settings: 57600, 8, N, 1, no flow control, TCP, port number 10001. The sensor output rate is 50Hz (20ms) with output format of ASICII.

It’s easier to read with a terminal program since the sensors’ measurements are reported in ASCII. DCM estimation and all measurements are delimited with “,”characters as well as a carriage return and line feed at the end of the data frame.

Format:

“ANG,roll,pitch,yaw,AN,gyroY,gyroZ,gyroX,accelX,accleY,accelZ,magnetomX, magnetomY, magnetomZ”

After “ANG”, roll, pitch, yaw are estimated angle value by on board DCM algorithm. The unit is degree.

After “AN”, the data are raw AD value for each sensor. Please note that the accelX, Y, Z value have been adjusted by subtracting the offsets by on board firmware.

Sample data string:

“ANG,0,0,10,AN, 379,378,379,1,-2, 243,4096,-1558,256”

Camera with Two Way Audio

You need to install the camera ActiveX control on your system by running the “AXISMediaControlSDK.exe”. You could find some sample codes (C++, C#, VB) in C:\Program Files\Axis Communications\AXIS Media Control SDK\samples and the corresponding SDK documents in C:\Program Files\Axis Communications\AXIS Media Control SDK\doc.

By using the Microsoft’s “Windows Media Encoder 9” and Axis video capture driver, you could also access this camera in Intel’s OpenCV as same as accessing a USB camera.
