Abstract: The paper proposes a new approach for detecting

alive human beings in devastating environments using a

low cost semi-autonomous robot. The proposed alive human

body detection system uses a specific set of sensors that

gives information about the presence of human in a stable

or movement condition and in alive or expired condition

and a low quality camera to acquire a video scene of the

debris environment. Having detected an obstacle or alive

human body, the set of sensors trigger the camera to show

live scene. The video is then displayed on a PC or a laptop

at base station and processed at lab. The alive human

detection system proposed in this paper is highly reliable as

it is managed individually or in a group. The data and

information required to be acquired and processed for

rescue operation are done using WI-FI. So, it is very cost

effective and faster to be applied in real-time operating

environment.

Keywords: semi-autonomous; human Detection;

temperature sensor; WI-FI

INTRODUCTION

Due to technological development, information about

different natural disaster can be predicted earlier. Now days,

natural disasters keep happening frequently because people

are disrupting the natural balance. Police, fire service and

paramedics are being deployed to minimize the loss of life

and property. Sometimes the rescue team cannot reach many

parts of the affected area due to the inability to search for

the live person in the debris.To reduce losses of lives and for

getting accurate information of a situation, a robotic system

can be used and modified.

A robot is a reprogrammable, multifunctional manipulator

designed to move materials, parts, tools or specialized

devices through variable programmed motions for the

performance of a variety of tasks. Basically a robot consists

of a mechanical structure, such as a wheeled platform, arm,

or other construction, capable of interacting with its

environment. Sensors to sense the environment and give

useful feedback to the device. Systems to process sensory

input in the context of the current situation and instruct

device to perform actions in response to the situation.

Surveillance robot is to recognize and detect motion

automatically around a robot's environment. The robot design

has been partitioned into sensor, control, and planning

subsystems. Robotic surveillance appliance is built on a

moving platform designed for surveillance and security tasks.

This robot can be operated in “remote eyes” or “automatic

trip” modes. This means it can be steered remotely by a

human watchman as a moving surveillance camera or it can

drive autonomously along an undefined route, detecting all

Inconsistencies in the video input. Secret surveillance in

tightly constrained spaces is demanded in many military and

civilian activities, such as cave-in enemy raids and indoor

hostage rescue missions.

Robots are used to do jobs that could be done by humans.

However, there are many reasons why robots are better than

humans in performing certain tasks.

Speed: Robot may be used because they are FASTER than

people at carrying out tasks. This is because a robot is really a

mechanism which is controlled by a computer.

EXISTING SYSTEM

Semi autonomous robot consists of gas sensor, PIR sensor ,

RF transceiver and receiver, ultrasonic sensor and IP camera.

The controller consists of a joystick which is used to drive

the robot in a controlled way. It detects the human presence

inside the affected area and gives the result about alive or

expired condition. It has ARDUINO MEGA controller board

and it costs high.

PROPOSED SYSTEM

Rescue robot consist of gas sensor, accelerometer,

temperature sensor, moisture sensor, camera and node red

server. A keyboard, which acts a remote control used to drive

the robot in a controlled way.DS18B20 Temperature sensor

sense the temperature of human body and the raspberry pi

camera shows the body motion .Using putty software a static

IP address is created and output is displayed in the webpage

by internet connection or Wi-Fi.

HARDWARE MODULE

Arduino

Arduino is an open source computer hardware that designs

and manufactures single-board micro

controllers and microcontroller kits for building digital

devices and interactive objects that can sense and control

objects in the physical world. Arduino board designs use a

variety of microprocessors and controllers. The boards are

equipped with sets of digital and analog input/output (I/O)

pins that may be interfaced to various expansion boards

(shields) and other circuitsSensor produces thermistors

capable of operating over the temperature range of -100° to

over +600° Fahrenheit. Because of their very predictable

characteristics and their excellent long term stability,

thermistors are generally

accepted to be the most advantageous sensor for many

applications including temperature measurement and control

RASPBERRY PI3

The Raspberry Pi is a low cost, credit-card sized computer

that plugs into a computer monitor or TV, and uses a standard

keyboard and mouse. It is a capable little device that enables

people of all ages to explore computing, and to learn how to

program in languages like Scratch and Python

THERMISTOR

Thermistors are thermally sensitive resistors whose prime

function is to exhibit a large, predictable and precise change

in electrical resistance when subjected to a corresponding

change in body temperature. Negative Temperature

Coefficient (NTC) thermistors exhibit a decrease in electrical

resistance when subjected to an increase in body temperature

and Positive Temperature Coefficient (PTC) thermistors

exhibit an increase in electrical resistance when subjected to

an increase in body temperature. U.S. Sensor produces

thermistors capable of operating over the temperature range

of -100° to over +600° Fahrenheit. Because of their very

predictable characteristics and their excellent long term

stability, thermistors are generally accepted to be the most

advantageous sensor for many applications including

temperature measurement and control.

GAS SENSOR(MQ5)

A gas sensor is a device which detects the presence of gas in

an area.This sensor interacts with a gas to measure its

concentration. Each gas has a unique breakdown voltage i.e.

the electric field at which it is ionized. Sensor identifies gases

by measuring these voltages. The concentration of the gas

can be determined by measuring the current discharge in the

device. The MQ5 gas sensor detects the presence of various

gases such as hydrogen, carbon monoxide, methane and LPG

ranging from 100ppm to 3000ppm.

.

TEMPERATURE AND HUMIDITY SENSOR (DHT11)

The DHT11 is a basic ,ultra low-cost digital

temperature and humidity sensor.It measures the humidity

and temperature of the surrounding in the affected

area.DHT11 digital temperature and humidity sensor is a

composite Sensor contains a calibrated digital signal output

of the temperature and humidity.
