THE LANDMINE THREAT

•There are 40-120 million landmines worldwide today.

•Landmines injure/kill about 10,000 every year.

•Landmines are long-term killers, active long after a war is over.

•Landmines are indiscriminate in their killing of people.

Yearly reports documenting the landmine problem worldwide

CHALLENGE OF DEMINING•Deminers face monumental task in clearing landmines.

•Most common method to find landmines is by metal detector.

•Dogs, bees, and rats can also find landmines.

•People will have to go in and still remove the landmine by hand with a prod.

•Process is fraught with dangers and long-term viable demining methods are needed.

Detectors are notoriously inaccurate

Hand prodding is very dangerous

AIM OF THE PROJECT

•Aim of this project is to design a robot that can detect a mine. •On detection of mine, it will forward the information to the controller. •After processing this information it transmit alert signals to the computer through RF, where this warning can be detected .

BLOCK DIAGRAM

WORKING OF THE PROJECT

•RF transmitter for controlling the movement of the robot.

•Signal is received by the RF receiver of the robotic unit.

•Microcontroller accordingly run the motor which in turn connected to the wheels of the robot.

•As the robot detect a mine through the metal detector, this will send a signal to the controller and the controller will then perform a desired action to show the detection of the mine by the robot.

METAL DETECTORSA metal detector is a device which responds to metal that may not be readily apparent.

USES Uses include de-mining (the detection

of land mines), the detection of weapons such as knives and guns, especially

in airport security, geophysical prospecting, archaeology and treasure hunting.

GPSThe Global Positioning System (GPS) is a

space-based global navigation satellite system(GNSS).

Provides reliable location and time information in all weather and at all times

and anywhere on or near the Earth when and where there is an unobstructed line of sight

to four or more GPS satellites.

How it worksGPS satellites circle the earth twice a day in a

very precise orbit and transmit signal information to earth. GPS receivers take this information and

use triangulation to calculate the user's exact location.

A GPS receiver must be locked on to the signal of at least three satellites to calculate a 2D position

(latitude and longitude) and track movement.

With four or more satellites in view, the receiver can determine the user's 3D position (latitude,

longitude and altitude).

Once the user's position has been determined, the GPS unit can calculate other information, such as speed, bearing, track, trip distance, distance to destination, sunrise and sunset time and more.

The GPS satellite systemThe 24 satellites that make up the GPS space

segment are orbiting the earth about 12,000 miles above us.

They are constantly moving, making two complete

orbits in less than 24 hours. These satellites are travelling at speeds of roughly 7,000 miles an hour.

GPS satellites are powered by solar energy. They have backup batteries onboard to keep them

running in the event of a solar eclipse, when there's no solar power.

RF AUDIO/VEDIO TRANSMITTER

•A Audio/video transmitter is a device which carries video and audio signals from one location to another.

•A Audio/video transmitter will normally come in the form of two components.

•One is the transmitter, or "sender“.

•The other is the receiver.

PROJECT MODULE DIVISION

•Manufacturing of project has been completed in 3 modules:

•MODULE 1:- Completion of Circuit diagram has been done. Along with this In module-1 the robotic section has been completed. In this module we’ll interface the motor drive and power supply to cy8c27443 microcontroller.

•MODULE 2:- In module-2 interfacing of A/V device and metal detector has been done.

•MODULE 3:- In module-3 interfacing of GPS tracker has been done.

APPLICATIONS•It can be used for the detection of land mine in military operation.

•It provides exact location of the mine.

•It can be used as a SPY robot.

•It can be used to track the location of the enemies through GPS.

•It provides real time video.

•It reduces the casualties in war zones.

APPLICATIONS Cont.•Accurate information about longitude, latitude, speed of device, direction of movement can be tracked by the GPS System fabricated in this robot.

•It can be used to provide the information about the damage in a building.
