  1. 1. ABHINAV KUNAL(1ME07EC001) ANIL KUMAR T(1ME07EC006) N.S.AVINASH SAI(1ME07EC044) NAVEEN KUMAR M(1ME07EC045) GUIDED BY: Ms. NATYA S Dept of E&C MSEC
  2. 2.  INTRODUCTION  PRINCIPLE  BLOCK DIAGRAM  EXPIEREMENTAL SETUP  ADVANTAGES  FUTURE IMPLEMENTATION  APPLICATIONS  CONCLUSION
  3. 3.  This project makes use of the cost effective bluetooth service provided by the cell phone in order to monitor and control the robot.  Cell phone captures the video and sends it to the PC for processing using the cell phone bluetooth.  After viewing the video in the PC through the provided GUI, user can move Robot in any required direction by sending RF signals from the PC.
  4. 4.  RF control signals from PC are sent from the RF wireless device connected to the PC and these signals are received by the RF device mounted on the mobile robot.  To control the movement of the robot appropriate sensing mechanism has been implemented through the microcontroller.
  5. 5. BLOCK DIAGRAMBLOCK DIAGRAM HARDWARE REQUIREMENTS BLUETOOTH DONGLE RF TRANSMITTER AND RECEIVER PIC MICROCONTROLLER RELAYS DC MOTOR SOFTWARE REQUIREMENTS J.D.K 1.6.0 J2ME 2.5.2 WIDCOM 5.0.1_BLUETOOTH DRIVER
  6. 6.  The Cell phone bluetooth technology is used to transfer the video captured by the movement of the robot to the PC.  The movement of the robot is controlled by the PC using RF signals.This is achieved by the RF devices in the PC and the Robot
  7. 7.  The PC acts as a server, which controls the movement of robot and processes the image transferred by the mobile through Bluetooth.  The Bluetooth dongle connected to PC establishes the Bluetooth link between the mobile and server SERVERSERVER
  8. 8.  The MAX232 is an integrated circuit that converts signals from an RS 232 serial port to signals suitable for use in TTL compatible digital logic circuits.
  9. 9.  Its a 28 pin IC with 3 ports.  The ports are port A, port B and port C.  Port A is used for analog inputs, port B is for data transfer and interrupts and port C is used for serial communication.  A 20 MHz crystal oscillator provides the clock signal.  It receives the data from server through MAX 232.  It transfers the received data to HT12E encoder.
  10. 10.  It is a 18 pin IC.  It receives the data parallelly and transmits it serially.  The transmission enable pin must be set HIGH.  It converts digital data to RF signals.
  11. 11.  It receives the encoded signals from HT12E.  Its transfers the received RF signals to the receiver end.  The range of the transmitter is 100 meters.
  12. 12.  It receives the RF signals from TXC1 transmitter.  It transfers these signals to HT12D decoder.  These signals are used in controlling the movement of the robot.
  13. 13.  The received RF signals are converted into digital data.  It receives the signal serially and transmits the decoded data parallelly to ULN2003.  The decoded data are indicated by the LEDs on the robot.
  14. 14.  LED – Light Emitting Diode.  It works on the basis of electroluminescence effect.  A light-emitting diode is a semiconductor light source  It indicates the data received by the receiver.
  15. 15.  It is a 16 pin IC.  The data received from the server is given to the ULN2003 which drives the relay as per the data, according to which the mobile robot changes its direction.
  16. 16.  A voltage regulator is an electrical regulator designed to automatically maintain a constant voltage level.
  17. 17.  Relay performs the switching action based on the data from ULN2003 driver.  These relays control the turn ON and turn OFF action of the DC motor.  Based on these switching actions the direction of movement of robot is controlled.
  18. 18.  DC motor works on the principle of Electromagnetism.  DC motor consists of 6 parts namely stator,rotor,commutator,axle, brushes and field magnets.  The DC motor is driven by the set of relays.
  19. 19.  A symbian based mobile phone is mounted on the mobile robot.  This mobile is bluetooth enabled.  The camera in the mobile captures the images and transfers it to the server through bluetooth.
  20. 20.  Mobile Robot has the capability to move around autonomously.If any hurdle is faced,PC redirects the robot.  The controls are stored in PC that acts as master cum server.  The video of the movement of the Robot is transferred from the mobile Robot to the master and processed.
  21. 21.  Bluetooth Technology is used to transfer the video.  After transferring the video the mobile robot waits for command or instruction from the master.  The interaction between the mobile Robot and the master takes place in the form of RF signals. The master has a wireless RF transmitter and the mobile Robot has a wireless RF receiver for this purpose.  To control the movement of the robot we also make use of appropriate sensing mechanism in the microcontroller mounted on the mobile robot.
  22. 22. Easy to use. Cost effective. More efficient. flexible in operation. No extra remote required. wide range of applications. Rugged in Operation.
  23. 23.  Implementation of zoom in and zoom out mechanism in the mobile.  Here we have done the project for a single cell pone but the same can also be used for 2 cell phones looking in different directions and this can give more in depth view of its usage.  We can replace the  Bluetooth by Wi-Fi so that we can have a lot better coverage area.
  24. 24.  It can be used in Surveillance applications.  Used in security.  Used in wild life research.  Used by defense.  Used in mines.  Used to access difficult terrains.  It can be used to explore remote locations.
  25. 25.  This project makes use of cost effective bluetooth technology to transfer live videos to the PC where the data can be processed.  The mobility of the Robot is an advantage as it can capture live video from almost any place.
