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.

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.
![Page 9: Blue robot seminar](https://reader035.vdocuments.net/reader035/viewer/2022062319/554a04b1b4c9055b7a8b5369/html5/thumbnails/9.jpg)
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.

to the receiver end.
The range of the transmitter is 100
meters.
![Page 12: Blue robot seminar](https://reader035.vdocuments.net/reader035/viewer/2022062319/554a04b1b4c9055b7a8b5369/html5/thumbnails/12.jpg)
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.
![Page 17: Blue robot seminar](https://reader035.vdocuments.net/reader035/viewer/2022062319/554a04b1b4c9055b7a8b5369/html5/thumbnails/17.jpg)
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.
![Page 18: Blue robot seminar](https://reader035.vdocuments.net/reader035/viewer/2022062319/554a04b1b4c9055b7a8b5369/html5/thumbnails/18.jpg)
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.
![Page 20: Blue robot seminar](https://reader035.vdocuments.net/reader035/viewer/2022062319/554a04b1b4c9055b7a8b5369/html5/thumbnails/20.jpg)
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.
![Page 21: Blue robot seminar](https://reader035.vdocuments.net/reader035/viewer/2022062319/554a04b1b4c9055b7a8b5369/html5/thumbnails/21.jpg)
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.

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.

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.
