ABSTRACT

We are presenting a Voice Control Spy Robot For Security System, which is controlled by usingwireless voice controller. This project we are using another technology is VOICE RECOGNITION whichcan also be easily interfaced. If the people want to move using voice command the robot moves tothe required position. The main aim of this project is to design and construct a voice operated controlsystem. This system acts as human-machine communication system. Speech recognition is the processof recognizing the spoken words to take necessary actions accordingly. User can also control theelectrical devices like fan, lift, door, etc. with the help of voice recognition system. It contains a devicecalled wireless CCD Camera which capture audio and video information and send using RF transmitterand receiver device. The maximum range up to which we are working is 80 metres.

INTRODUCTION

Here is a Voice Operated Spy Robot circuit using voice Recognition. It can capture Audio aswell as video information’s from surrounding area and can be sent to remote station though RF signal.The maximum range is 80metres. This robot consist of mainly two sections. They are as follows:

Voice control section: This section controls the input voice signal which contains microphone andcontrols the input for accurate output.

Video transmitting section: It consist of CCD camera which capture audio and video information asinput and transmit to remote station (computer) as a output.

EXPLANATION

We are Presenting a project named as VOICE CONTROLED SPY ROBOT FOR SECURITY SYSTEMWhose input is voice signal and output is video signal at receiver. These project consists mainlyof two sections :-

1. Voice Controlled Section.

2. Video Transmission Section.

1. Voice Controlled Section :- This crcuit uses encoder and decoder Ic. RF Transmitter andReceiver Module is used for voice control. H-bridge circuits are used for driving motors. Two 12vDC /100RPM gear motors are used as drivers.

The working of the circuit is as follows:

When we speak any word the microcontroller Ic will generate 8 bit address and 4 bit data. The input directions in voice form are used for setting the address for Ic. Then the RF transmitter will send the 8 bit address and 4bit data to receiver then the RF receiver receive the 8 bit address and 4 bit data and decoder Ic will decode the data thus enabling the output. Thus the output signals generated will controls the H-bridge circuitry which then rotate the motors.

2. Video Transmission Section :- In This project we are going to use a wireless CCD camera which works on 12V/DC supply. The 12V/DC supply is taken from the battery placed in robot. T camera has a receiver, which is placed in a remote station. Its output signals are in the form of audio and video. These signals are directly connected to a TV receiver or a computer through a tuner card.

PROPOSED SYSTEM

ADVANTAGES

The visual gathering from spy robot can be recorded and viewed to human directly via computer.

Humans are removed from direct exposure to potentially dangerous situation; Robotic systems can perform many security and surveillance functions more effectively than humans, Giving us information that humans can’t get.

This can perform tasks faster than humans and much more consistently and accurately; they can capture moments just too fast for the human eye to get; they can entertain us and help us in certain tasks.

DISADVANTAGES

Communication devices mostly use similar frequency so interference occurs if address is not specified.

It cannot be work beyond limit.

To cover longer distance Power required should be more.

APPLICATIONS

The Wireless spy Robot has been designed in such a way that it can fulfill the needs of the military, the police and armed forces.

It has countless applications and can be used in different environments and scenarios.

For instance, at one place it can be used by the armed forces, military purposes, while at another instance it can be used for spy purposes.

It can be also used there were humans were unable to reach.
