Agricultural Robot
(2015-12-21T09:47:14Z) Shameek, Das; Naveen, .M; Yachamaneni, Srikar
Developed agriculture needs to find new ways to improve efficiency. One approach is to utilize available technologies in the form of more intelligent machines to reduce and target energy inputs in more effective ways than in the past. Precision Farming has shown benefits of this approach but we can now move towards a new generation of equipment. The advent of autonomous system architectures gives us the opportunity to develop a complete new range of agricultural equipment based on small smart machines that can do the right thing, in the right place, at the right time in the right way.The application of agricultural machinery in precision agriculture has experienced an increase in investment and research due to the use of robotics applications in the machinery design and task executions. Precision autonomous farming is the operation, guidance, and control of autonomous machines to carry out agricultural tasks. It motivates agricultural robotics. It is expected that, in the near future, autonomous vehicles will be at the heart of all precision agriculture applications . The goal of agricultural robotics is more than just the application of robotics technologies to agriculture. Currently, most of the automatic agricultural vehicles used for weed detection, agrochemical dispersal, terrain leveling, irrigation, etc. are manned. An autonomous performance of such vehicles will allow for the continuous supervision of the field, since information regarding the environment can be autonomously acquired, and the vehicle can then perform its task accordingly
Fire Detection and Extinguishing Robot
(2015-12-21T09:56:53Z) Md., Nizamuddin; R. Sunil Kumar, Reddy; Santhosh, CM
Our goal is to develop an intelligent multi sensor based fire extinguisher robot in our daily life. We design the fire detection system using four flame sensors in the fireextinguisher robot, and program the fire detection and fighting procedure using sensor based method. The fireextinguisher robo is equipped with four thermistors/flame sensors that continuously monitor the temperature the need for a device that can detect and extinguish a fire on its own is long past due. Many house fires originate when someone is either sleeping or not home. With the invention of such a device, people and property can be saved at a much higher rate with relatively minimal damage caused by the fire. Our task as electrical engineers was to design and build a prototype system that could autonomously detect and extinguish a fire. Also aims at minimizing air pollution.in this project we design a fuzzy based microcontroller controlled robot. It is the robot that can move through a model structure, find a burning oil derrick (lit candle) and then extinguish it with help of a blower. This is meant to simulate the real world operation of a robot performing a fire extinguishing function in an oilfield. Fuzzy logic provided an appropriate solution to the otherwise complex task of mathematically deriving an exact model for the non-linear control system upon which conventional control techniques could then be applied. We are using the popular 8 bit microcontroller the 8051 family microcontroller. Program code to control the fire extinguisher robot is written in EMBEDDED C.
Mems Based Home Automation System
(2015-12-21T10:04:03Z) Nigel, T Peter; Dishank, .V; Jithin, O
At home, we generally operate (switch on/off) all the electrical and electronics appliances such as fan, light, cooler, air conditioner, and so on through switches of the regular switch board. This manual switching of any home appliance is an inconvenient method for physically disabled or elders when frequent switching operation is required. Thus, this conventional manual switching method has to be overcome by an easier method of switching so that physically disabled people can easily operate home appliances without making much movements i.e. they don't have to get up and go to the switch board to operate appliances and can do it at the comfort of their position without much movement. This can be done using a MEMS IC. In this, hand gestures are used to either switch on or switch off appliances.
GSM Based Real Time Automated Meter
(2015-12-22T06:07:11Z) Febin R, Francis; Prashanthi, P.S; Pruthvidhar, D
With the problems faced in the present conventional electricity billing system, where, errors due to human involvement in acquiring meter readings and also to take steps in order to reduce consumption of electricity, we bring out a device which will give the customers the benefit of controlling his/hers expenditure on electricity based on a budget. It also reduces man power employed by the electricity board to a great extent. Also, in reaching to rural and remote areas with ease. In practice, we make use of a GSM technology for billing purposes which, takes reading on real time basis of the units of electricity being used and calculates the price (in Rupees) of the amount of units of electricity that has been made use of. The information of this usage is provided to the customer every fortnight via an SMS on his cell phone. A SIM card loaded into the GSM module will be capable of sending this information to the customer. The same information will also be shared with the EB (electricity board) via an SMS with the help of a GSM module that also works on real time basis.
Design and Implementation of an On-Chip Permutation Network
(2015-12-22T06:10:35Z) Aishwarya, Tripathi; Dheepna, Mohandas
A trend of multiprocessor system-on-chip (MPSoC) design being interconnected with on-chip networks is currently emerging for applications of parallel processing, scientific computing. This report presents the silicon-proven design of a novel on-chip network to support guaranteed traffic permutation in multiprocessor system-on-chip applications. The proposed network employs a pipelined circuit-switching approach combined with a dynamic path-setup scheme under a multistage network topology. Permutation traffic, a traffic pattern in which each input sends traffic to exactly one output and each output receives traffic from exactly one input, is one of the important traffic classes exhibited from on-chip multiprocessing applications. The dynamic path-setup scheme enables runtime path arrangement for arbitrary traffic permutations. The circuit-switching approach offers a guarantee of permuted data and its compact overhead enables the benefit of stacking multiple networks.

(2015-12-22T06:15:05Z) Ankit, Mishra; Santhosh, Kumar S; Sreejith R, Warrier
The project involves design and development of algorithms for an autonomous robot system deployed for surveillance activities. The work entails design of routing algorithm, communication system, application server and PID controller using MATLAB and Open Source platforms. Routing algorithm design includes feature matching, mapping of images to grid based graphs and deriving routing meta-data. The communication system is responsible for transferring routing meta-data from server to the client and application data from client to server over the internet backbone using protocol suited for deployment requirements. Communication system entails detailed study and design of buffer size requirements and read/write cycle to buffer (to synchronize bytes that are in buffer and application processing rate). The Client is an ARM based computer responsible for acquisition of data and act as liaison between routing algorithm process at server end and the PID process at the client end that is responsible for movement of robot. Application server is designed to aid surveillance buy monitoring the application data (live video stream) transmitted by the client over HTTP protocol and performing facial recognition using PYTHON and OPEN CV libraries. The design of ground bot entails design of PID controller, placement of power source, routing of signals/power lines to components and packaging within the robot chassis Modelling of routing algorithm is one of the key aspects in the project. An aerial acquired image usually contains a lot of detail in a cluttered environment. The ability to match features of the robot and obstacle to database is vital for autonomous nature of the system. Dijkstra's algorithm and its derivatives are used for finding the shortest paths between nodes in an environment. Currently, autonomous robot systems are at their infancy. Development of algorithms are key to sustainability of these systems and it’s our aim to contribute to this development through this project.
Fire Security System for Public Transport
(2015-12-22T06:18:45Z) Ankita, Patel; Navjot, Kaur; Yashaswini, P
Fire accidents are very frequent in our daily lives. Fire on a running vehicle is more catastrophic than on a stationary one, since fanning by wind helps spread the fire. When these accidents occur in remote areas or during night hours the loss or damage caused is relatively high. The damage is heavier due to improper reach of service at right time due to inefficient communication. This time delay causes greater damage. Thus, eliminating the time between when an accident occurs and when first responders are dispatched to the scene decreases the damage. The delay can be eliminated by identifying the fire accident and notifying the concerned authorities and passengers as soon as possible. The proposed system is very efficient and robust when applied to detect and prevent fire catastrophes. In case of fire, the vehicle is forced to stop, an alarm is raised and then a text message is sent to the fire authority. The message contains information about the location, where the fire accident occurred. Receiver at the fire station is a smart phone having an application of Google map that shows shortest route to the destination. At the same time, primary measures such as water sprinklers and exhaust fans are used to reduce the degree of damage caused by the fire. The major aim of this project is not just to identify if the fire occurred, but also to inform fire authorities and take primary measures to control the fire.

Wireless Power Transmission for Electric Vehicle Battery Charging
(2015-12-22T06:28:50Z) Arun, Yogash S M; Darshan, S; Girish, Kumar R
The main objective of this project is to develop a device for wireless power transfer. The concept of wireless power transfer was realized by Nikolas tesla. Wireless power transfer can make a remarkable change in the field of the electrical engineering which eliminates the use conventional copper cables and current carrying wires. Based on this concept, the project is developed to transfer power within a small range. This project can be used for charging batteries those are physically not possible to be connected electrically such as pace makers (An electronic device that works in place of a defective heart valve) implanted in the body that runs on a battery. The patient is required to be operated every year to replace the battery. This project is designed to charge a rechargeable battery wirelessly for the purpose. Since charging of the battery is not possible to be demonstrated, we are providing a DC fan that runs through wireless power. Moreover this technique can be used in number of applications, like to charge a mobile phone, iPod, laptop battery, propeller clock wirelessly. And also this kind of charging provides a far lower risk of electrical shock as it would be galvanically isolated. This concept is an Emerging Technology, and in future the distance of power transfer can be enhanced as the research across the world is still going on.
Tri - Axis Motion Detection using Mems for Mouse Navigation System (Human Mouse)
(2015-12-22T06:33:43Z) Bharath, V; Rahul, S; Vijay, Kumar S N
Easy Input is a head-controlled keyboard and mouse input device for paralyzed users. This study describes the motivation and the design considerations of an economical head- operated computer mouse. In addition it focuses on the invention of a head-operated computer mouse that employs tilt sensors placed in the headset to determine head position and to function as simple head operated computer mouse. One tilt sensor detects the lateral head motion to drive the left or right displacement of the mouse. The system uses accelerometers to detect the user's head tilt in order to direct mouse movement on the monitor. The clicking of the mouse is activated by the user's eye blinking through a sensor. The keyboard function is implemented by allowing the user to scroll through letters with head tilt and with eye blinking as the selection mechanism. We constructed an interface system that would allow a sin-Wady paralyzed user to interact with a computer with almost full functional capability. That is, the system operates as a mouse initially, but the user has the ability to toggle in and out of a keyboard mode allowing the entry of text. This is achieved by using the control from a single eye, tracking the position of the pupil for direction, and using blinking as an input. As detection of eye motion proved too challenging, we built an accelerometer based tilt detector to determine head motion, so that, although not as applicable in this particular case, it might be used by a quadriplegic individual.
Frequency Monitoring of Industrial Machine
(2015-12-22T06:39:37Z) Bidya Bhushan, Bihu; Saaket, Upadhyay
Since the dawning of Industrial revolution in 1790, industries play a huge part in the society and it is one of the pillars of modern society. Every country has its own industry, and the backbone of any industry is its machine. Machines are the driving force of any industry. Now the question arises, what happens if the machine stops working? Sometimes a part of a machine may malfunction but the machine still keeps on working. After a point of time the machine will completely stop working. What if we were able to know about the deficiency in the machine before it was immobile? We would be able to redeem the money squandered due to the halt in production. Our frequency monitor system does exactly that. It tells about the fault in the system before it becomes a hindrance to production. This paper showcases all the evidence required to build this system. It describes the use of piezo to sense the frequencies and the use of Arduino to store and show the obtained frequencies.
Fuzzy Logic Based Smart Traffic Control
(2015-12-22T06:45:09Z) Deepshika, .B; Poojita, Jonnalagadda; Prasanna, Kumar .V
This project demonstrates intelligent traffic control with capability of controlling the traffic flow according to the varying situations of traffic flow with the help fuzzy logic. The control of traffic is done using 8051 microcontroller. The fuzzy allows the 8051 to take decisions according to number of vehicles on each road and as a result control the timing of green signal of the respective lanes. The input to the fuzzy is number of vehicles, given into the system by a PIR sensor. The intelligent traffic control does not restrict to only control of 3 lights, but also gives freedom to take decision during emergency situations, such as giving way to fire engines and ambulance vehicles. The project is demonstrated by three different modules. Module 1 demonstrates the traffic light working with the fuzzy input vehicles in 4-road junction. The system classifies the traffic into 4 types: isolated, light, medium and heavy. The number of vehicles is put into either one of the categories and the timing of the green signal varied based on the category. If emergency is detected, then the green signal of the respective lane is made to blink for a considerable long duration, so that the emergency vehicle leaves the junction. Module 2 employs a Passive infrared sensor that detects motion. This PIR sensor is used to count the number of moving vehicles and the number is displayed on a 16X2 LCD display. This serves as the input to the fuzzy code. Module 3 demonstrates the detection of emergency vehicles. It employs a RF transmitter and receiver. The RF transmitter is placed on the emergency vehicle, and the receiver at the traffic junction. When the transmitter is in the range, and receiver detects the vehicle, receiver initiates the emergency signal. It sends a emergency message to traffic control room on a 16X2 LCD display.
Automatic Highway Signaling System and Digital Fuel Indicator
(2015-12-22T06:49:30Z) Dhanush, R; Abhishek, B J; Naveen, Kumar
This project is developed in the vision of preventing accidents in the highways. A prior intimation is given to the driver about the obstacles present in the highways such as steep curve, bends, bridges, temporary work on progress etc. to avoid mishaps and also focuses on creating a digital display of the exact amount of fuel contained in the vehicles tank and also helps in cross checking the quantity of fuel filled at the petrol bunk. Finally once the fuel is filled at a bunk the device also sends a sms to the vehicle owner indicating the quantity, and date, time. This project also provides a provision for the vehicle owners to monitor and get information about their vehicles regarding the amount of fuel filled by their drivers and thus avoids cheating.
Microcontroller Based Clinometer
(2015-12-22T06:53:25Z) Harsha, Kumar K.S; Jithendra, Kumar B; Kadiresh, M
The word clinometer is derived from ‘clino’ which means slope or incline. Clinometer is an instrument whose main purpose is to find the height and the distance from one given point to the top of a building/object. The height of the building/object is calculated along with the distance from the foot of the building/object to the place where we are standing. Currently it can be calculated manually by using trigonometric functions along with the help of a Clinometer. So we present a solution by using a microcontroller (which will calculate the distance and height of the building/object using trigonometric functions digitally) and a rotating pointer to point towards a building/object. Hence we can find the heights of tall buildings within fraction of seconds with utmost accuracy. This is a simple and wonderful innovation which would be extremely beneficial to mankind.
Solar Power Monitoring
(2015-12-22T06:56:29Z) Jyotsna, .R; Kiran, Kumar .R; Neha, .P
The era of fossil fuels, as a main part of energy supplies, is coming to end by next some years. Then using new forms of energy instead of traditional forms of energy is necessary. Remarkable daily amount of energy from the sun, and the fact that using solar energy is free of environmental pollution and harmful gases, makes solar energy as proper source to replace fossil fuels. The areas where there is sufficient amount of solar energy, a solar power plant is the best way of generating electricity. Growing concerns about energy availability have increased consumer and government interest in solar power as a viable alternative to traditional power sources. In fact, large concentrated solar power plants are capable of creating the thermal energy equivalent to conventional fossil fuel power plants. A centralized system is needed to monitor the Solar Energy Plant. The system should be able to take in different sensor readings, and transfer data to a centralized location for storage or report generation. If any solar panel has problem we can check that from anywhere.The main essence of Solar Power Station Monitoring System Using Ethernet is to design and implement data monitoring system of a solar power station like voltage, current and wattage using ARM CORTEX M3 CORE and Ethernet connection for data monitoring applications.

(2015-12-22T06:59:40Z) Kasthuri, C.N; Komal, Saha; Shashwata, Jaganath
Fish-like swimming could have considerableamount of energy savings while it is used for small autonomousunderwater vehicle. But, analysis of fish motion dynamicsin the water, demands great attention. Here, in this work,we analyze fish motion dynamics in the water and design robotic fish which is capable of navigating in three dimensional space with the use of pectoral fins. The robotic fish movementin a three dimensional space is simulated in arduinoIDE . The skeleton of the fish which consists of 3-joint mechanical tail (rear part) and two pectoral fins,are designed and fabricated. The joints are actuated by servo motors. Experiment shows that the mechanical tail is capable of generating near sinusoidal wave through its body. The control signals for the servo motors are generated by an onboard Atmega-328 micro controller.
Error Correction Capability using Reed Solomon Encoder / Decoder Algorithm and its implementation FPGA and ASIC Platforms
(2015-12-22T07:04:55Z) Kushal, .S; Kiran, .N; Detphung Gwra, Narzary
In coding theory, Reed–Solomon (RS) codes are non-binary cyclic error-correcting codes invented by Irving S. Reed and Gustave Solomon. They described a systematic way of building codes that could detect and correct multiple random symbol errors. By adding t check symbols to the data, an RS code can detect any combination of up to t erroneous symbols, and correct up to [t/2] symbols. As an erasure code, it can correct up to t known erasures, or it can detect and correct combinations of errors and erasures. Furthermore, RS codes are suitable as multiple-burst biterror correcting codes, since a sequence of b+1 consecutive bit errors can affect at most two symbols of size b. The choice of t is up to the designer of the code, and may be selected within wide limits. In Reed-Solomon coding, source symbols are viewed as coefficients of a polynomial P(x) over a finite field. The original idea was to create n code symbols from k source symbols by oversampling P(x) at n > k distinct points, transmit the sampled points, and use interpolation techniques at the receiver to recover the original message. That is not how RS codes are used today. Instead, RS codes are viewed as cyclic BCH codes, where encoding symbols are derived from the coefficients of a polynomial constructed by multiplying P(x) with a cyclic generator polynomial. This gives rise to an efficient decoding algorithm, which was discovered by Elwyn Berlekamp and James Massey, and is known as the Berlekamp - Massey decoding algorithm.
Wireless Communication using LI - FI
(2015-12-22T07:09:08Z) Lakshmeesh, S; Nouble, Sameem M A; Sri, Hari K P
A wireless optical networking technology that uses light-emitting diodes (LEDs) for transmission of data can be termed as Li-Fi also known as Visible Light Communication. The main purpose of this paper is particularly to show the advantages of Li-Fi technology in audio transmission and device switching using an embedded web server with light as the medium of transmission. Here the LED is used as the source of light for transmitting the necessary information to the receiver. This technology enables in sending more data to the receiving end very quickly. Li-Fi makes use of transmitter fitted with LED lamps that can illuminate a room as well as transmit information. As this technology uses LEDs, there is no need of separate infrastructure to be deployed exclusively for this purpose. Thus existing LED lights in conjunction with a transmitter circuit can be used for data transmission which can be received by the receiver equipped with appropriate circuitry thereby reducing the use of Radio Frequency for wireless transmission of data.

The work is to design and develop an interfacing electronics to obtain the input data from a charge sensor to obtain both analog and digital stream of data at the output. The input signal is amplified using cascaded connection of two-stage amplifier. The analog output obtained is digitized using an Analog to Digital Converter. The Analog to Digital Converter used here is the Flash ADC. The Analog to Digital Converter used here should convert analog output to a four bit digital output.
Multilevel Security for ATM Systems
(2015-12-22T07:15:49Z) Manochitra, Ravichandran; Heeraa, Kalaiselvan; Vikas, G
Identification and verification of a person today is a common thing; which may include door-lock system, safe box and vehicle control or even at accessing bank accounts via ATM, etc which is necessary for securing personal information. There is need for improve security in ATM transactions. Due to tremendous increase in the number of criminals and their activities, the ATM has become insecure. ATM systems today use an access card and PIN for identity verification. The Personal Verification Number (PIN) does not give good security. The fingerprint is unique and cannot duplicate by others. This system combines the pin verification and fingerprint recognition technology for identification. With fingerprint recognition technology we embedded the GSM modem connected to the microcontroller. The GSM module is used to generate the 4 digit one time password (OTP) and it send to the main user mobile number when the user enrol the fingerprint to gain access the ATM. The fingerprint of the card holder is collected and stored in the database corresponding to the Bank account details. Every fingerprint which is placed at ATM is checked across the database. The 4 digit one time password should be entered using the Keypad. After enter all the correct information customer can begin the further transactions. The biometric features cannot be replicated; this proposal will go a long way to solve the problem of account safety. We have used the Arduino Mega 2560 as a core controller. The system uses R305 fingerprint scanner to capture fingerprints with its DSP processor and optical sensor and SIM900 GSM module for generation and transmission of 4 digit OTP. This system can be employed at any application with enhanced security because of the uniqueness of fingerprints. It is convenient due to its low power requirement and portability.
