Abstract - Science is a field developing in a rapid phase in order to create the technology which can make

human life easier. Nowadays, many innovations and inventions are made in the field of defence to reduce

the loss of human lives. One such invention is Camouflage Robot that plays a vital role in reducing the

damages that occur during disasters. This robot is designed to work on the principle of Chameleon's

camouflaging technique which is one of the most natural and primitive methods for avoiding detection.

The main objective of this paper is to implement a multi-functional army robot consisting of various

sensors. The proposed system consists of a wireless camera for live video streaming surveillance and a

colour sensor is used as a part of camouflaging feature. In the proposed model cloud based IOT interface

with Blynk app and Wi-Fi module are used for retrieving, storing and recovering information to increase

the range of communication.

I.INTRODUCTION

In the modern combat techniques employed by various militant forces across the globe, stealth and ability to

maneuver in inaccessible areas plays a key role. The idea of the proposed system is to use robots which are

capable of disguising itself in order to infiltrate the enemy campsite [1]. The word robot means "A machine

which is capable of performing complex series of actions automatically that is programmable by a computer."

These robots used in defence are usually employed with the integrated system, including cameras, sensors and

video screens [2]. The main motive behind Camouflage Robot is to reduce human losses in terrorist attacks or

military operations. Many military organizations take the help of robots in the risk prone areas. Camouflage

Robot acts as a virtual spy that can quietly enter into enemy area and send information via camera to the

controller [10]. The movement of the robot is remotely controlled using a mobile. Robots can be made to

interact and cooperate more closely with human beings by incorporating additional features such as robustness

and autonomy. A versatile perception and recording of different parameters in this robot is accomplished using a

multi-sensor platform. In this system an interfacing module is incorporated to remotely sense the object

parameters using IoT (Internet of Things). Finally, the purpose of the project is to design, manufacture and

operate a robot using a remote controlled device. A small mobile robot is designed which can duplicate its

colors similar to the platform it moves on, appearing as camouflaged to the outside world.

II. PROPOSED METHODOLOGY

A Camouflage Army Robot is designed in such a way that it can reproduce the color independently at various

areas with specific spots of the ground surface which allows the robot to mock up as a checkerboard of multiple

colors i.e. the various colors it drives over. In the implemented system the movement of the robot can be

controlled in any required direction using IoT platform and smart phone which receives the information from

the sensors and camera.

The main processor used in the proposed system is Arduino Mega, which is a microcontroller board based on

the ATmega2560. The ATmega series is much more advanced since it has many more peripherals that can be

easily programmed when compared to 8051 Microcontroller. An ultrasonic sensor is incorporated which

measures the distance to an object by using sound waves and helps in detecting the obstacles [5]. Here a passive

device, PIR (passive infrared sensor) or PID (passive infrared detector) sensor is used which measures infrared

light radiating from objects in its field of view by detecting the movement/motion of living things. This sensor

works on reflection and radiation properties [6]. A LM35 temperature sensor is employed which measures the

temperature through an electrical signal with the help of thermocouple or RTD (resistance temperature detector).

The operating range of LM35 is from -55°C to 150°C. To detect the leakage of different gases such as Alcohol,

Benzene, CH4, Hexane, LPG, CO (carbon monoxide), a MQ3 Gas sensor is used which has fast response time

and high sensitivity. Its sensitivity can be adjusted by using the potentiometer. A metal detector is used for

finding metal inclusions hidden within objects, metal objects buried underground and also for detecting the

presence of nearby metallic devices such as bombs and guns. The color sensor employed detects the color of the

ground, usually in the RGB scale [3]. A DC motor which is a class of rotatory electrical machine is employed

and that converting direct current to mechanical energy. Here 2 DC motors are used for the movement of the

robot which is controlled via mobile (Android application). Also, Node MCU ESP8266 is deployed as a Wi-Fi

module which includes firmware that runs on the ESP8266 Wi-Fi SoC.

For the software implementation, we have used Arduino IDE in the proposed system to program the Arduino

mega board. An integrated development environment (IDE) is a software application that provides

comprehensive facilities to computer programmers required for software development. It generally consists of a

source code editor built-in automation tools and a debugger. The Arduino IDE supports C and C++ languages

using special rules of code structuring. The android application used in this system is BLYNK, which is an

internet based tool that helps in mapping the hardware circuitry onto android phones. Here the robot movement

and other sensor data values are displayed in Blynk application. For the purpose of live video streaming, a

wireless IP address based Wi-Fi camera is used[2]. The live video streaming can be viewed on a smart phone by

making use of an android application V380S.

V. CONCLUSION AND FUTURE SCOPE

The Camouflage Army Robot is highly favourable in circumstances where it is impossible for human beings to

reach or monitor. The implementation of our system is purely driven by usage of PIR sensors, Ultrasonic

sensors, DC motors and camera etc. Overall, this robot is a multi-functional device that reduces the strain on

humans during calamities. The camouflage robot system provides a helping hand to our security forces in

detection of intruders and trespassers. Moreover, the camouflaging feature makes it difficult to detect the robot

by naked human eye. There is scope to improve the system by configuring it with multi-colour camouflaging as

our implemented system camouflages only in RGB scale.
