Project-Mobile based fire detecting and Extinguishing Robot

Dear Friends,
I am submitting my first project report which is little interesting and educational.As per the title it is machine which is controlled by our mobile.
It is one f the latest technique that we ever had. It will make you learn how to use micro-controller and the importance of micro-contrller in our scientific life.
You can also know how a mobile that we use for our entertainment, calling,massaging etc can also be used for remote operation of the device from any place of the world.

This device works on the principle of DTMF encoding and decoding.
Before telling you about the project, we should first know what is DTMF

DTMF-Stands for Dual Tone Multi Frequency used on our mobile system from the time of invention of this device.
So DTMF is direct algebraic summation of amplitude of two cosine(Sinusoidal) waves in real time.It is the code which is generated ech and every time we press the keys on our 12 number system(0-9,*,#) mobile.According to the code you can also hear the different sounds generated from your mobile.

Let me give some example-
1 = 697+1209, 2 = 697+1336,
So 697 and 1336 are the amplitudes of the waves generated at the encoder which is present in each and every mobile.

Robot
A re-programmable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks."-- From the Robot Institute of America, 1979.

In simple words Robot is a human created and manipulated device which is used for the human to make the work of the human easier. just like a machine.

It does all the things that is previously coded in it or re-coded at our desire.

This time the robot I am talking about is mobile controlled and manually operated one.

Micro-controller-A micro-controller is a small computer on a single integrated circuit containing processor core, memory and programmable input output peripherals.

Its the device which can be programmable according to our requirement using assembly level languages.

Motors-
These are the bidirectional motors that are used in the robotic application .It can move in both direction according to the command given by the relay ckt.
It works on the principle of Electromagnetic operation.
The motors that are used in this project are PMDC motors or Permanent Magnet DC motors.
This motor consists of axle and battery leads which cause the spin of motor according to the connection made through the leads.
The axle holds the armature and the commutator . The armature is a set of electromagnets(3).
