3. INTRODUCTION:
 This project taken from embedded system.
 Embedded system is combination of hardware and software.
 Embedded system is used to perform a single task.
 In this project the robot control based on message.
 Sent message from mobile to GSM modem .
 Based on message the robot move the forward or backward or
right .
 In this project used wireless communication.
 GSM modem for communication purpose.

4. AIM:
 The main aim of this project to control the robot trough GSM in
anywhere in the earth.
 The other important objective that are associated in installing of
robotic system is;
1. Saving of manpower.
2. Ability to work in any type environment.
 The other one object of this project to build a low cost and
efficient wireless robotic system.

5. EXISTING SYSTEMS
 Designed and developed an land rover robot motion is
controlled by using an bit 8 bit microcontroller.
 To move in all direction like forward, reverse, right and left as
per the commands given by the controller.
 Communication between robot and mobile is bidirectional
communication, which takes place by DTMF with 9600bps.

6. PROPOSED SYSTEM:
 This system is made more useful by migrating from 8bit to 32bit
ARM 7 microcontroller.
 The high range GSM transmitter and receiver are used.
 A GSM modem is used send SMS.
 In industries different type of sensors are used to develop.

8. FUNCTIONS:
1.POWER SUPPLY
 The project requires low power.
 This consist a 9v power supply source and a power regulator
(7805)to get 5v power supply.
2. GSM MODEM
 GSM modem is a one type of modulator
demodulator.
 GSM supports data transfer speed is up to 9.6kbps,it allowing
the transmission of basic data services such as SMS.
 GSM operates on the 900 MHz, 1800 MHz and 1900 MHz .

9. 3.MICROCONTROLLER:
 In this project we used a 32bit ARM7 microcontroller.
 The micro controller connect GSM modem interface with a
RS232 cable.
 This microcontroller contains 512KB flash memory,32KB RAM
and additional 8KB for USB.
 It has 2 UARTs for communication purpose.
 It has a pipe line architecture and low power RTC(real time
clock).
 It has 2 ports (P0,P1),we use only P0.
 It contains 32pins it is used for input and output connection
purpose. A1 GLOBAL INSTITUTE OF ENGINEERING AND TECHNOLOGY, MARKAPUR

10. 4.LCD
 LCD is used for to display the motion
of a robot like forward, reverse or right side.
5.H-BRIDGE
 H-Bridge is a one of the IC(L293D),it is also
known as motor driver.
 L293D inputs are take from microcontroller and
amplifies their power to control the motor.
 Wide supply voltage range:4.5v to 36v and High-Noise-
Immunity input.
6.DC MOTORS
 It is mainly used for moving a robot .
 It requires 12v of DC supply.

11. SOFTWARE:
1.KEIL
 It is used for developing a programming code.
 By using this software to create a hex file.
2.PROTEUS
 we can design a hardware in this software.
 The output can verified in this software.
3.FLASH MAGIC
 Flash magic is used to dump a programming code(hex file) into
hardware.
A1 GLOBAL INSTITUTE OF ENGINEERING AND TECHNOLOGY, MARKAPUR

12. IMPLEMENTATION
 The power supply 3.6V is connected IC pins 23,6(VDD&GND).
 The GSM modem is connected to any one of UARTs trough a
RS232 cable.
 The LCD (16 2) is connected to 8pins of PORT0.
 The H-Bridge(L293D) 4 input pins are connected to any 4pins
of PORT0.
 The H-Bridge amplifies the input signal and send to the motors.
 The 2motors are connected to 4pins of the H-Bridge.
 The LCD and H-Bridge pins are connected to PORT0 as per the
program.

13.  The USB cable is connected between PC and hardware kit.
A1 GLOBAL INSTITUTE OF ENGINEERING AND TECHNOLOGY, MARKAPUR
 The developing program is dumped to hardware kit trough Flash
magic and USB.
 By using a mobile we can send a message to GSM modem, it
demodulate that message to send a microcontroller.
 The microcontroller compare GSM information and programming
code information.
 If the information is correct the controller generate a input to H-
bridge.
 Based on controller instruction it will controls the motors.

14. ADVANTAGES
• It requires low power.
• Robotic workers never get tired.
• 24/7 continuous working.
• It can move from one location to another location.
• Can be made to perform even the most dangerous tasks.
• It is simple to operate and is very reliable.
• It reduce the man power.

A1 GLOBAL INSTITUTE OF ENGINEERING AND TECHNOLOGY, MARKAPUR

18. CONCLUSION:
 In our project , the robot is designed to move by our command
and also own according to the command given by the program.
 In this project ,we design in such a way that this robot can be
moved anywhere and it can get the information of particular
place.
 This project is very much useful in the paces where a human
cannot go into the place like ground canals, smoke oriented
caves.
 An alerting message will be sent to a prescribed SIM using GSM
modem.
