ABSTRACT: As it is known embedded system is a special-purpose computer system designed to perform adedicated function. As a spice we also includedrobotics domain and achieved this projectsuccessfully. In this project, an automationsurveillance system is achieved using PIR sensorwhich senses the human and more over the robotconsists of a weapon detector. Once the intruder hasbeen sensed, the location will be tracked using GPSand is sent as a message to nearby police stationthrough GSM modem placed .Mean while the robotfollows the intruder with the help of ultrasonic andinfra red sensor, and a camera is used for capturingthe images and transfer it to CCTV.

AT89s52 Microcontroller The AT89S52 is a low-power; high- performance CMOS 8-bit microcontroller with 8K bytes of in- system programmable Flash memory along with this It also provides
ULTRASONIC SENSOR: Ultrasonic sensors (also known as transceivers when they both send and receive) work on a principle similar to radar or sonar. Here WTS601 ultrasonic sensor is used in this project for the following factors As detection of the object is up to 12m. The frequency at which it is operating is 40 kHz. And the power consumed by the sensor is (+ or -) 5v of DC. It works on the basis of the following condition to detect the distance of the object from the robot. Distant to object = speed of sound * (time it takes to hear echo come back/2)
PIR SENSOR: A Passive Infrared sensor (PIR sensor) is an electronic device that measures infrared (IR) light radiating from objects in its field of view. Here “DYP-ME003” pyro - electric device is used because of the following features As detection range
IR SENSOR: Infrared sensor “MOC7811” is used in this project in order to provide the following features As it can also modulate the IR to achieve better distance and immunity. The receiver diode has a very high resistance And also when IR is incident upon it, the resistance decreases sharply to the order of a few kilo Ohms or even lesser. There are two such sensors used here as it is responsible for the movement of the robot in left and right position respectively. This movement is based on the infrared emitted from the human or object in order to follow its position.
METAL DETECTOR The inductive proximity will sense all metals. The exact point at which a target will be detected is influenced by the type of metal, its size and surface area. The “LM18- 3008PA” metal detector is used in this project and it can sense metal/ bomb within the 2m. The voltage used is about 12-30v.
GSM MODEM GSM Modem provides full functional capability to Serial devices to send SMS and Data over GSM Network. The “FARGO MAESTRO 20” modem is used of the band range of 900 and DC of 5-3v with 450mA.
GPS GPS receivers help us to navigate back to a starting point or other predetermined locations without the use of maps or any other equipment. In conjunction with accurate maps like ones provided by the USGS, and other basic tools like a compass and Lat/Long or UTM scales, one can navigate to identified locations on maps or take readings from a location that they are at or have been at and plot those locations on a map. All of these features make it a very desirable and useful technology for a mirid of activities including Search and Rescue, Aviation and Nautical navigation, hiking, hunting, camping, fishing, and many more. All of these various GPS users have unique needs which require different levels of understanding and skill in using this technology.
Relay A relay is an electrically operated switch. The function of the relays in the control unit is for controlling the movement of robot’s base with respect to the on or off position of the two infrared sensors and an ultrasonic sensor. There are five “JQC-3FC (T73)” relays in which the two of it controls the left and right motion of the robots movement whereas the next two controls forward and backward movement. The rest one relay is used for controlling camera which is in on position only when ultrasonic sensor is on.
UART An UART, universal asynchronous receiver / transmitter is responsible for performing the main task in serial communications with computers. The device changes incoming parallel information to serial data which can be sent on a communication line. A second UART can be used to receive the information. The UART performs all the tasks, timing, parity checking, etc. needed for the communication. The only extra devices attached are line driver chips capable of transforming the TTL level signals to line voltages and vice versa. Basically uart contributes of two components viz Max232 ic. Rs232 serial cable.
MICROCINTROLLER BOARD The microcontroller board is the heart of the robot since it carries the main program. To the base of the controller several components like IR sensor, PIR sensor, GSM/GPS modem , etc used in the robot is connected. It consists of the following components : AT89s52 Microcontroller LCD to display the command being executed and more over it s 40 pin LED to display that the circuit is on Voltage regulator Reset pin to make the controller to start from zero again 1uf,10uf and 100uf capacitors Diode Transistors UART
MOTOR DRIVE CIRCUIT: It is the main circuit to drive the robot effectively. i.e., it is responsible for the movement of the robot and it is connected to the base of the robot which has wheels for the motion. It consists of the following components: Four relays to gain the isolated motion for the robot Four LEDs to display which relay is enable Diode Resistors A chip which has the program to operate the relay with the help of the IR sensors.
Circuit to activate thecamera: To this board a camera is effectivelyconnected to relay which is programmed insuch a way that the camera is active onlywhen the ultrasonic sensor is active. Thecamera is connected to the relay as it acts likea switch. The camera is also connected to thelocal server and it records the video of theintruder in the concern as the real timeapplication. It consists of the followingcomponents: One relay LED Diode switch Resistor And a chip that carries the program tooperate the relay
APPLICATIONS: The main purpose for designing this robot is that toimplement it in defense sector to sense human and detectweapon/ bomb with the human or buried in the place wherehuman cannot fetch for it. The sensors with smaller range frequencies are sufficientto install this robot in residents. The sensors with very high frequencies are required toinstall this robot in the IT industries. This robot can be installed in banks, especially in theplaces where jewels are kept (locker area). In the educational institutions, this robot can play a vitalrole in the areas of library and laboratory where valuableequipments are kept.
