Transcript of ALIVE HUMAN DETECTION ROBOT USING ANDROID PHONE

ALIVE HUMAN DETECTION ROBOT USING ANDROID PHONE
ABSTRACT
A new approach for detecting alive humans in destructed environments using an autonomous robot is proposed.

Using this system monitoring system using specific sensors and camera to record, transmit and analyze conditions of human body.

The video is then displayed on the screen.

This system has the potential to achieve high performance in detecting alive humans in devastated environments relatively quickly and cost-effectively.

Once the people are located it immediately gives audio and visual alerts to the android phone.
INTRODUCTION
EXISTING SYSTEM
In destructed environments it is impossible to detect them. Detection by rescue workers becomes time consuming and due to the vast area that gets affected it becomes more difficult.

ABSTRACT

INTRODUCTION

EXISTING SYSTEM

MODULES

TECHNICAL DETAILS
A unique Passive Infrared sensor is used in the project which emits infrared rays to detect humans.
As live human body emits thermal radiation it is received and manipulated by the PIR sensor to detect humans.
Alert is given to the android phone after detecting each alive human.
A camera is attached to the robot to view the video on the screen.

The robot consists of a four wheel geared drive with DC motors attached to perform forward and reverse movement.
PROPOSED SYSTEM
The project proposes an autonomous robotic vehicle that moves in the destructed area and helps in identifying the live people and rescue operations.

Hence precious life can be saved by timely detection in natural calamities even without the help of large number of rescue operators.
MODULES
Arduino microcontroller

GSM Module

PIR Sensor

Motor and Motor driver

camera

Android

ARDUINO MICROCONTROLLER

Arduino is a single-board microcontroller to make using electronics in multidisciplinary projects more accessible. .

Signals from PIR sensors are given to the microcontroller and this microcontroller will digitize the signal and send it to the GSM.

The controller has peripheral features like inbuilt ADC, required to get the signals from the various sensors.
GSM
It is used to send and receive data between robot and the control unit.

GSM is a digital wireless communication protocol.

It is a high power communication technology.

It provide reliable delivery of critical data between devices.
PIR sensors are passive infrared sensors.

They detect change in the heat and this can be used to detect movement of people. It has digital output and can be directly given to the digital pins .

CONCLUSION
Hence many lives can be saved by using this autonomous vehicle during a disaster in a short duration .
This vehicle can be improved by using high range sensors and high capacity motors. Some more sensors like mobile phone detector, metal detector etc. can be implemented to make this vehicle more effective.
SOFTWARES USED
Eclipse SDK used to develop android part.

Arduino IDE used to program microcontroller.


MOTOR AND MOTOR DRIVER

motor denotes the robot which can move over earthquake prone areas.

Motor drive is the interfacing circuit between microcontroller and motor.

DC motors cannot be interfaced to the microcontroller directly because it requires much higher voltage and current. Motor drive is used for this.
The hardware consists of an open-source hardware board designed around an 8-bit Atmel AVR microcontroller, or a 32-bit Atmel ARM.

The software consists of a standard programming language compiler and a boot loader that executes on the microcontroller.

The Arduino integrated development environment (IDE) is a cross-platform application written in Java, and is derived from the IDE for the Processing programming language and the Wiring projects.
ARDUINO BOARD
GSM

GSM is a digital wireless communication protocol.

GSM uses a combination of TDMA (time devision multiplexing)and FDMA(frequency devision multiplexing). This means that users A and B are not only sharing the channel in time but also frequency
.
PIR SENSOR
The temperature of an object determines how much radiation is emitted and at what particular wavelength

The higher a body’s temperature, the more radiation emitted and the shorter the peak wavelength of the emission
The heat that generates electricity (here, an electric signal of small amplitude). Since these sensors do not have an infrared source of their own, they are also termed as passive.
CAMERA
camera consist of a transmitter which hass the capability to transmit clear audio and video.
The signal is received by an receiver at the other end.
receiver and the pc has a wired connection.
ANDROID
Using eclipse IDE a XML file is created as UI
to control the robot

It also has the facility of giving information about the detection via GSM module and calling init.message() in android.

Thus detection of alive human is indicated to the user as pop up message

The following algorithm will be followed to
implement the performance of Robot.
Step 1: Start
Step 2: Initialize micro controller
Step 3: Initialize motors
Step 4: Initialize PIR sensor
Step 5: Monitor PIR sensor
Step 6: If person detected
information is send to mobile
Motor rotates in specified direction
Step 7: Monitor PIR sensor
Step 8: Stop
