What is a Robot ?

An electrical or mechanical or electromechanical, programmable or non programmable multifunctional manipulator designed to move material, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks.

Features of Robot

1 .M o b il it y :It possesses some form of mobility. 2. Programmability: It can be programmed to

accomplish a large variety of tasks. After being programmed, it operates automatically.

3. Sensors:On or around the device that are able to sense

the environment and give useful feedback to the device.

4. Mechanical capability:Enabling it to act on its environment rather than merely function as a data processing or computational device. 5. Flexibility: It can operate using a range of programs

and manipulates in a variety of ways.

COMPONENTS OF ROBOTS

1.MECHANICAL DESIGN 2.ELECTRONIC COMPONENTS 3.PCB BOARD 4.MOTORS 5.MICROCONTROLLER 6.SENSORS

INTRODUCTION

1.This is a robot which can be controlled by using cell phone. 2.A GSM-controlled robotic application is a Robot that can be controlled, and navigated by the usage of mobile networks or GSM (Global Sytem for Mobile) technology. It can handle and execute commands derived from mobile phone bases initiation and can also be programmed to work autonomously as per the situation demands.

TECHNOLOGY USED

DTMF (Dual-Tone-Multiple-Frequency) DTMF signaling is used for telecom

signaling over analog telephone lines in the voice frequency band between telephone handsets and other communication devices and the switching centre.

In other words DTMF is a method of instructing switching system of the telephone numbers to be dialed, or to issue commands to switching systems

Working of the IC

* Tone is attached to 0.1 micro F capacitor on the top corner.

* Mount the circuit on the robot with auto answer mode on.

* Connect one wire of the headphone to the wire and other to the ground.

* The tone is then passed to amplifier for filtering. * OE is the output enable pin, high on this pin will enable

the output . * D0,D1 ,D2 and D3 are the decoded output of the IC. DV is data valid pin, its a output pin, Set to high itself by

IC when valid data is available on these bits. *RT/GT and EST are pins for setting effective time duration

of tone to check for authenticity.

WHAT NEW COULD BE ADDED?

Well we controlled our robot through the mobile network but it can be controlled by the server (web server) in future.

This model is composed of three components: Home server (PC server), Mobile Internet and Home Robot. Home server is responsible for passing

message and information between Home Robot and Mobile Internet. Mobile Internet, which includes Mobile Network and Internet, accomplishes the tasks requested by home master from far away.

Change!!!!

We can also assemble many appliances by the use of this same technology.

APPLICATIONS

The presented robot has numerous applications in daily life :

1. It can be used inS P Y I N G P U R P O S E S to get the confidential details of anybody from remote area without making our life in danger.

2. TheC A M E R A which has been installed can provide the live streaming of the places where a human can’nt reach.(especially during natural calamities like EARTHQUAKE)

3. We make of use of robot in small pieces of work whenever we are away from HOME .

4. It can be also used by ourD E FE N S E agency in many cases.
