INTRODUCTION PRINCIPLE BLOCK DIAGRAM EXPIEREMENTAL SETUP ADVANTAGES FUTURE IMPLEMENTATION APPLICATIONS CONCLUSION

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.

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.

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

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

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.

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.

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.

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.

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.

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.

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.

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.

A voltage regulator is an electrical regulator designed to automatically maintain a constant voltage level.

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.

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.

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.

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.

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.

Easy to use.

Cost effective.

More efficient.

flexible in operation.

No extra remote required.

wide range of applications.

Rugged in Operation.

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.

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.

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.
