Operation Scenario

Diagram below illustrates the typical operation scenario. The Jaguar-4x4-wheel 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-4x4-wheel 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).

Operation of Jaguar Robot

End user could develop his own Jaguar control program using the supplied development API and tools. Here, we will show you how to control the robot using the included “Jaguar Control Program” (You need to install Google

Earth program first).

Turn on/off the Platform

Please follow the below steps to turn on the robot.

1. Turn the main switch to "ON" position.

2. Press the start button for a while (around 1 second) then release.

If you see the green LED on the start button is on, the system is powered up.

If not, please check the battery to make sure it is fully charged.

Turn the main switch to "OFF" position, the system will shut down.

Using Dr Robot Jaguar Control Program

This program will demonstrate how to control and navigate the Jaguar-4x4-wheel, and how to interpret, process, display and log multi-sensor information. This program is provided with source code (c#).

 updates motor encoder reading, motor temperature, board voltage and battery voltage measured at 10Hz;

 reads and displays IMU and Laser Range sensor data;

 displays GPS readings on the Google Earth;

 displays and controls Axis camera.

Once you start this program, you will see a “Login Window”

It will read all the configuration information from “outdoorrobotconfig.xml” under c:\DrRobotAppFile\.

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

Google Earth is then loaded (this 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 when trying to connect with Google

Earth website. You will not get the correct Latitude and

Longitude position by clicking on map before the map loading is finished. When loaded, click “OK” button.

“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 closed.


- 11 -

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

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 shown in the video window.

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

Further Development & Programming

The Jaguar Control program

The Jaguar Control program is written with Visual Studio 2008 express (in C#) under .Net 3.5 framework. You could download the development tools (Visual Studio 2008 express under .Net 3.5 framework) free from

Microsoft. Please refer to the “Dr Robot Application Development Notes on C# Programming for Robot Control” for further information.

The control program uses the supporting components and libraries that should have been installed when you install the control program from the installation CD:

1.

DRROBOTSentinelCONTROL.OCX:

detail.

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

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.

Motion Control/Sensing System

Jaguar-4x4-Wheel comes with a special version of PMS5005 as its motion control and sensing board. It follows the Dr Robot WiRobotSDK protocol. User could control and access Jaguar by Dr Robot ActiveX control

(DrRobotSentinelActivexControl.ocx) and WiRobot gateway program.

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

The communication port is connected at Ethernet 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-4x4-Wheel System with ActiveX control,

myJaguar is DrRobotSentinelActiveXControl.

Wheel Motor control: private void myJaguar_MotorSensorEvent( object sender, EventArgs e)

{ leftRearWheelMotor.encoderDir = myJaguar.GetEncoderDir1();

leftRearWheelMotor.encoderPos = myJaguar.GetEncoderPulse1();

leftRearWheelMotor.encodeSpeed = myJaguar.GetEncoderSpeed1();

rightRearWheelMotor.encoderDir = myJaguar.GetEncoderDir2();

rightRearWheelMotor.encoderPos = myJaguar.GetEncoderPulse2();

rightRearWheelMotor.encodeSpeed = myJaguar.GetEncoderSpeed2();

WheelMotor.output leftFrontWheelMotor.outputPWM = myJaguar.GetMotorPWMValue4();

rightFrontWheelMotor.outputPWM myJaguar.GetMotorPWMvalue5();

leftRearWheelMotor.outputPWM myJaguar.GetMotorPWMValue1();

rightRearWheelMotor.outputPWM myJaguar.GetMotorPWMValue2();

}


- 21 -

You could 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 *

34.498);

}

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

Also you could read left/right wheel motor encoder in this event. private void myJaguar_CustomSensorEvent( object sender, EventArgs e)

{

// front left track motor double tempM =

Trans2Temperature(( double )myJaguar.GetCustomAD5());

tempM = double .Parse(tempM.ToString( "0.00" ));

lblTemp1.Text = tempM.ToString( "0.00" );

// front right track motor

tempM = Trans2Temperature(( double )myJaguar.GetCustomAD6());



// rear left track motor




// rear right track motor




leftFrontWheelMotor.encoderPos = myJaguar.GetEncoderPulse4();

leftFrontWheelMotor.encodeSpeed = myJaguar.GetEncoderSpeed4();

leftFrontWheelMotor.encoderDir = myJaguar.GetEncoderDir4();

rightFrontWheelMotor.encoderPos = myJaguar.GetEncoderPulse5();

rightFrontWheelMotor.encodeSpeed = myJaguar.GetEncoderSpeed5();

rightFrontWheelMotor.encoderDir = myJaguar.GetEncoderDir5();

}

To stop all motor, you could use: myJaguar.DcMotorPwmNonTimeCtrAll(16384, 16384, 16384, 16384, 16384,

16384);

For track/wheel motor control, we use independ-drive mode. Under this mode, PWM channel 3 is driving Left front wheel motor, PWM channel 4 is driving right front motor, PWM channel 0 is driving left rear motor and

PWM channel 1 is driving right front mtoor.

To move forward with full power myJaguar.DcMotorPwmNonTimeCtrAll(32767,0,NOCONTROL,32767,0,NOCONTROL);

To move backward with full power myJaguar.DcMotorPwmNonTimeCtrAll(0,32767,NOCONTROL,0,32767,NOCONTROL);


- 22 -

To turn left with full power myJaguar.DcMotorPwmNonTimeCtrAll(0,0,NOCONTROL,0,0,NOCONTROL);

To turn right with full power myJaguar.DcMotorPwmNonTimeCtrAll(32767,32767,NOCONTROL,32767,32767,NOCO

NTROL);

For encoder speed/position control of each motor, you could referee “DrRobot

Jaguar4X4 Motor Control Demo” program and you could find the source code in the installation folder.

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 automatically, stop all the motors if it does not received any data package in

5 seconds.

Laser Scanner

Laser Ranger sensor (4m version, URG-04LX) is connected to Ethernet 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

GPS sensor output interface is RS232 serial port, and connected to Ethernet 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


The output interface for this IMU sensor module is serial port. It is connected to Ethernet module-2 port 1. 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. All measurements are delimited with “,”characters as well as a carriage return and line feed at the end of the data frame.

Format:

“$seq,accelX,accleY,accelZ,,gyroX,gyroY,gyroZ,magnetomX, magnetomY, magnetomZ#”

"seq" is data package sequency number, value is in range: 0 ~255.

After “seq”, the data are raw AD value for each sensor.

Sample data string:

“$2,9,1,255,20,40,3,235,4000,20#”

Please note the magnetic sensor will be measured every 220ms, so if the output value is 0, means no new magnetic sensor data in this data package.

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.

Advanced Development

Please refer to document “GPS-IMU Sensor Module and Outdoor Autonomous Navigation Program” for detail on autonomous navigation programming using the Jaguar GPS and IMU system module.

Support and sample codes are available for using OpenCV, LabVIEW and MATLAB. Please contact [email protected]
