1ST PRIZE VOICE CONTROLLED ROBOTIC VEHICLE MANIKANTAN R. (1BT17IS007) The voice controlled vehicle is controlled using a simple smart phone (android), through the app named “AUD voice control” which only works on android. The command given is received and recognized by Google then the command is transmitted from mobile through ‘Bluetooth’ in the form of character variables. This character variables received by the Bluetooth module (H-C 05 Module) is sent to the Arduino micro controller (Arduino are circuit boards in which “Microcontrollers are mounted” this can be coded using with a platform called “Arduino” which is a higher level language similar to “C-language”. Arduino board helps the user to interface many sensors, drivers, displays etc, through the I/O pins) then the stepper works according to the instruction given by the Arduino and the Motor is driven accordingly.

2ND PRIZE ELECTROMAGNETIC TRAIN HEMANTH KUMAR M.C (1BT17CS011), RAHIL KHAN (1BT17CS030), MOHAMMED OWAIS (1BT17CS023) & B.S.SAPNA KUMARI (1BT17CS004) In the project we have built an “electric train,” utilizing uninsulated copper wire, a battery, and powerful magnets. The result is a fascinating experiment that displays the basic principles of electromagnetism and engineering. This experiment is guided towards STEM education and outreach, particularly for underfunded schools. The end product is a train made of a battery and magnets that propels itself through a coil of wire using electromagnetic force.

3RD PRIZE CHILDRENS’ SAFETY IN SCHOOL VAN VINODHINI.S.K.S (1BT17CS053) & SHANKRAMMA (1BT17CS041)

The project is based on school children safety in their respective school van. The project is basically a working model consisting microcontroller of 8051 family, RFID reader(Radio frequency identification),GSM Modem etc. A program containing children name along with their parent’s phone number respectively, was coded into the memory of microcontroller using embedded C language. The aim of the project is when a student enters into the school van with all the settings containing the working model in it, the student has to place the ID tag in front of the RFID which displays his/her name and id number on LCD placed along with the model. After the detection immediately the parents of the respective student gets a name saying that child had got into the school van. In the same manner, while leaving the bus when the child places his/her id before the RFID which detects, displays and sends the message immediately telling the child has left the bus.

SMART SHOE MURALI KRISHNA(1BT17EC012), VIJAY REDDY (1BT17CS055) & VENKATESH PRASAD (1BT17CS049)

The smart shoe is a shoe that charges your phone on the go as you walk, run, jog etc. The smart shoe works with pizo plate (piezoelectric sensor), which inturn works on the principle of a pizo electric transducer. When pressure is applied on the shoe i.e. when you walk or run, electricity is generated and the battery installed in the shoe is charged. The battery inturn charges the phone connected to it via usb .

TYPES OF ENERGY KALYANI (1BT17CS015) & KAVYASHREE.T.N. (1BT17CS017)

ENERGY is defined as the capacity to do work. In the project Solar Energy is converted to Wind Energy with the help of Solar Panel or Solar Cell. From which Light Energy is produced or Electricity generated and also Sound Energy from the Light energy. A 100 Watt bulb is used which is assumed as a Solar Energy , by which the radiations emit (UV radiations from SUN). The radiations from the Sun(SOLAR ENERGY) absorbed by the device called SOALR PANNEL which is made to absorb solar radiations by which we can convert Solar Energy into Wind , Light , and Sound Energy.

SMARTPHONE CONTROLLED ROBOT R. SRINIVAS (1BT17IS008) The project is about a robot which can be controlled by an android smartphone. The app sends commands via Bluetooth connected to microcontroller. Microcontroller controls motors. The robot works through a “cxem car” an android app. The app is designed and made available to open source. The app and source code can be downloaded from https://engineerts.weebly.com. While device is not connected, the red led is continuously flashing. In smartphone in cxem car app search for Bluetooth device name HC-05 device. Connect to it, add passcode “1234”. While connection is on, the led blinks once in a while. Now the robot can be controlled by the smartphone interface. On large scale, it can be used to develop robots with military applications. It is fast moving, robust and sensitive hence, can be used in rescue operations. This simple architecture is also useful for educational robotics, because students can build their own robots with low cost and use them as a platform for experiments in several courses.

ACCELEROMETER BASED HAND GESTURE CONTROLLED ROBOT SHASHI BHARATH (1BT17CS038), MANJUNATH (1BT17CV004), YASHASH KUMAR (1BT174CV009), SAI MAHESH (1BT17CV008) & ADITHYA (1BT17CV001)

In many application of controlling robotic gadget it becomes quite hard and complicated when there comes the part of controlling it with remote or many different switches. It is quite complicated to control the robot or particular machine with remote or switches, sometime the operator may get confused in the switches and button itself, so a new concept is introduced to control the machine with the movement of hand which will simultaneously control the movement of robot. A Gesture Controlled robot is a kind of robot which can be controlled by hand gestures not by old buttons. You just need to wear a small transmitting device in your hand which includes an acceleration meter. This will transmit an appropriate command to the robot so that it can do whatever we want. The transmitting device includes a ADC for analog to digital conversion and an encoder IC(HT12E) which is used to encode the four bit data and then it will get transmitted by an RF Transmitter module. At the receiving end an RF Receiver module receives the encoded data and decode it by and decoder IC(HT12D). This data is then processed by a microcontroller and finally our motor driver is ready to control the motor. AUTOMATIC STREET LIGHT CONTROL SYSTEM BINDU PATIL (1BT17CS006) & CHANDHANA S. (1BT17CS007)

The project is about Automatic Street Light Control System. It is a simple and powerful concept, which uses transistor (BC 547 NPN) as a switch to switch ON and OFF the street light system automatically. It automatically switches ON lights when the sunlight goes below the visible region of our eyes. (e.g in evening after Sunset). It automatically switches OFF lights when Sunlight fall on it ( i.e on LDR ) e.g in morning, by using a sensor called LDR(Light Dependent Resistor) which senses the light just like our eyes. By using this Automatic system for street light controlling, we can reduce energy consumption because the manually operated street lights are not switched off properly even the sunlight comes and also not switched on earlier before sunset. In sunny and rainy days, ON and OFF time differ noticeably which is one of the major disadvantage of using timer circuits or manual operation for switching the street light system .

ROOM HEATER RAKSHITHA S.(1BT17CV007) & MANJULA V. (1BT17CS021) Room heaters are used to heat a small space and are normally portable or fitted to a wall. Most room heaters use gas or electricity. They consume a lot of gas or electricity if used to heat up a space. Ideally, room heaters should only be used as a secondary or supplementary source of heat. Even then, we should use the right heater for the space we want to heat, and carefully control the temperature and the time we have the heater on. Heaters that have these controls are often cheaper to run.There are two types of room heaters- Electric room heaters and Gas room heaters. Electric room heaters are expensive to run as compared to Gas room heaters. A comparison model has been structured so as to promote the use of Gas room heaters. WIRELESS TRANSMISSION OF CURRENT LALIT KUMAR TRIPATHY (1BT17CS019) Wireless Transmission of Current is a method of transferring current from one coil to another coil due to mutual induction. A copper coil is taken and winded up 60 turns (primary coil). Again taking copper coil and winding up 30 turns (secondary coil), the connection is done with connected transistor. Now in the secondary coil we connect a LED bulb to know the deflection induced in the secondary coil. We connect a 9 volt battery to the primary coil. And the outcome is the light glows. It can be used in transformer, hydroelectric power station, wireless charging of mobile phones and other gadgets. SMART TRAIN BRIDGE HUSNA C. (1BT17CS013), HARSHITA (1BT17CS022) & RASHMI PRIYA (1BT17CS032)

The model of display is an automatic smart train bridge for railway station. We have placed 3 ir sensors one near the station one in middle and one far away from the station. We see that the traffic signal and a buzzer beep sound when the train is sensed by the first ir sensor which is far away from the station. The traffic light becomes green which was yellow in color before. When the train passed through the second sensor the traffic light becomes red which gives the signal to other train that already train is in the station . Here the first ir sensor acts as detector which detects the train far away which is going to enter the station. So don’t enter the station. Simultaneously here we can hear beep sound and the bridge will get open. Beep sound is to inform the people that the train is approaching. When train goes out of the station, it passes through ir sensor 3 and the bridge comes back to its original position and the traffic light turns yellow in color.

STEAM POWER GENERATOR

SAMYUKTHA N. (1BT17CS034), ANU OKULA (1BT17CS003) & AMRUTHA G. (1BT17CS002)

The steam power generator is based on UK’S electricity which is generated in power stations using fossil fuels. Thermal energy released from the burning fuel is used to boil water to make steam, which expands and turns turbines. This drives the generators to produce ELECTRICITY. BABCOCK & WILCOX boiler can generate steam with steam pressure ranging from 11.5 to 17.5 bar. The evaporative capacity ranges from 20,000 to 40,000 kg/hour. Steam is thus primarily used to run steam turbines and generate electric power.

TIN ELECTROPLATING ON COPPER

NIKHILK.(1BT17CV006),KARTHIK(1BT17CS016),BHUVAN(1BT17CS005)&HIMANSHU (1BT17CS012)

Electroplating is an electrochemical process where metal ions are transferred from a solution and are deposited as a thin layer onto surface of a cathode. The setup is composited DC circuit with an anode and a cathode sitting in a bath of solution that has the metal ions necessary for coating or plating. Electroplating can enhance chemical properties-increase corrosion resistance, physical properties-increase thickness of part, mechanical properties-increase tensile strength and hardness

BURGLAR ALARMS

HEENA M. (1BT17CS010)

Burglar alarms are networks of integrated electronic device working together with a central control panel to protect against thefts and other possible illegal entries, as well home intruders. The sensors are typically installed in doors and windows that expose potential intrusions. The alarm will sound once the circuit is closed. When sensor detects the movement in the door or window it would send signal to the control box which would in turn send signals to the alarm device. Burglar alarms are used in residential , commercial , industrial and military properties for protection against burglary or property damage as well as personal protection against intruders.

TRANSIT ELEVATED BUS

NAVEED LONE (1BT17CS025), GOWHAR LONE (1BT17CV002), MUKESH KUMAR (1BT17CS024)

The Transit Elevated Bus (TEB) is a new bus concept where a straddles above road traffic. For the road for the bus, two options are available: rails can be laid on the edges of the lanes that the bus occupies, or two whiteline can be painted on the road to facilitate use of autopilot technology. Rails would offer less wheel rolling resistance and better energy efficiency. For either option, it may be necessary to widen the lanes occupied by the bus to accommodate the bus wheels and undercarriage whilst allowing other vehicles to pass under the bus. Since the bus is no higher than a tractor-trailer, roadway overpasses will usually not be a problem. The bus would have alarms to warn cars traveling too close to it, and signals to warn other vehicles when it is about to turn. It would have inflatable evacuation slides similar to those of an aircraft. Optional features could include sensors to keep it from colliding with a person or object (such as an overheight vehicle in front), warning lights and safety curtains at the rear to keep drivers of overheight vehicles from going underneath, repeater traffic signals underneath to relay the indications of traffic signals up ahead, and animated light displays to simulate stationary objects to prevent disorientation of drivers underneath. Amongst other benefits the main benefit is that it is expected to relieve .

PARKING PLANT ASHRAY (1BT17ME004), ADITHYA (1BT17ME001), SANDEEP (1BT17ME019), SHASHIKUMAR (1BT17ME020) & BALACHANDRA (1BT17ME005)

The number of vehicles is increasing day by day in rapid manner. It causes the problem of traffic and congestion. To overcome this problem A FPGA based parking system has been modeled. The parking system has two main modules i.e. identification module and slot checking module. Identification module identifies the visitor. Slot checking module checks the slot status. These modules are modeled in HDL and implemented on FPGA. A prototype of parking system is designed with various interfaces like sensor, interfacing, stepper motor and LCD. ARTICLES ARTIFICIAL HEART SAYALI (1BT17CS040) An artificial heart is a prosthetic device that is implanted into the body to replace the original biological heart. It is distinct from a cardiac pump, which is an external device used to provide the functions of both the heart and the lungs. Thus, the cardiac pump need not be connected to both blood circuits. Also, a cardiac pump is only suitable for use not longer than a few hours, while for the artificial heart the current record is 17 months. This synthetic replacement for an organic mammalian heart (usually human), remains one of the long-sought goals of modern medicine. Although the heart is conceptually a simple organ (basically a muscle that functions as a pump), it embodies complex subtleties that defy straightforward emulation using synthetic materials and power supplies. The obvious benefit of a functional artificial heart would be to lower the need for heart transplants, because the demand for donor hearts greatly exceeds supply. In 1982, Seattle dentist Barney Clark became the first human to receive a permanent artificial heart, a device known as the Jarvik 7. The Artificial Heart uses magnetic and fluid levitation from rocket system. This technology can reduce friction in device to increase working efficiency and extend life span of power generator. This technology used can reduce damage to the blood pump to work longer. Fuwai Cardiovascular Hospital in also developed artificial heart using magnetic levitation and later planted them in three patients from June to October 2017.These artificial hearts were typically used on patients while they were waiting for heart transplant or to permanently replace heart in case heart transplants are not possible. In 2013, scientists planted man-made heart in sheep, which survived for 120 days in good health. Then hearts were then placed in six other sheep and all survived 100 days or longer, which proved that heart is qualified for batch production. Research is being done in several areas to improve the quality and use of artificial hearts. Researchers are looking into reducing the size of artificial hearts so that they can be totally implanted inside the chest. Work is also being done to develop artificial heart batteries that are small, long-lasting and implantable, and which can be recharged across the patient s skin. Biologically superior materials are being developed to reduce the tendency for blood to clot and the need for blood-thinning medicines (anticoagulants). These materials will be used to line the internal chambers of artificial hearts. Artificial hearts 5 INF-001-C Research is also being done into stem cells, which may be used to replace damaged heart muscle cells and restore heart muscle function. If this is possible, it would prevent heart failure and ultimately reduce the need for heart transplants and artificial hearts.

ARTIFICAL INTELLIGENCE DEEKSHA REDDY (1BT17EC004)

Artificial intelligence is a study and design of intelligent agents, where intelligent agent is a system that perceives its environment and takes action in which maximizes its chances of success. The term “ARTIFICAL INTELLIGENCE “ is applied when a machine mimics “cognitive” functions that humans associate with other human minds, such as learning and problem solving. The scope of AI is disputed as machines become increasingly capable , tasks considered as requiring intelligence are often removed from the definitions , a phenomenon know as AI effect , leading to the quip . Capabilities general classified as AI of 2017 include successfully understanding human speech, competing at the highest level in strategic games system autonomous, intelligent routing in content delivery network and military simulations.
