(2018-06-26T06:29:53Z) Rajesh, B K; Sachin, G; Vinay, M; Vishal, Durgad
Fused deposition modeling (FDM) is an additive manufacturing technology for 3D printing layer by layer. The main purpose of research is to develop some mechanical properties for FDM printed parts with variable fill density and obtain effective result and to encourage manufacturer to adopt the method of 3D printing. The material most commonly used in FDM is ABS, PC, PLA and mixtures. This work was being done on using ABS filament of diameter (1.75mm). This is printed using 3D printer, with 0.3mm thin layer by layer technique. Variable fill density 70%, 85%, 100% was tested for tensile strength (ASTM D638) and flexural strength (ASTM D790), using the printed parts and obtained test result (Peak load, break load and strain). For getting good quality of printed parts, influence factors must be considered such as material properties, machine specification, printing conditions and process parameter. Experimental results were carried out to obtain a optimum result based on their dimensional stability

This project is designed for the sole purpose of safety and accessibility for physically challenged people. It is made up of a resilient material i.e Mild Steel which can withstand heavy loads at a cheaper cost. We have incorporated a high torque motor for better weight range and a rack and pinion. We have concluded that this model can be scaled up to accommodate different vehicles and also we have tested 3 criterion for safety stability, Load capacity and speed. This ensures that the mechanism operates at a constant speed for variable loads hence reducing the jerk that may occur. We believe that this can be put to use in various parts of our society which would help the physically challenged depend less on others for simple tasks.

(2018-06-26T06:15:49Z) Suraj, Skanda R; Akarsh, H R; Prem Kumar S, Banagar; Sharankumar, R R
Energy is a key input for technological, industrial, social and economical development of a nation. However, a large number of consumers in domestic, agricultural, commercial and industrial sectors are faced with a situation of energy availability that is characterized by inadequate quantity, poor quality, unaffordability, un-sustainability and negative environmental consequences. A wide variety of Chulha or biomass stoves are used in Indian kitchen sand road side tea stalls and restaurants. These stoves emit smoke, ash and excessive heat creating uncomfortable and unhealthy environment for the user. Combustion rate is not well controlled. The efficiency of these stoves is quite less, generally not exceeding 28 -32 %. The waste which cannot be degraded by bio-chemical route like agricultural waste, wood waste can be converted into useful fuel through the process called Gasification. The inverted downdraft gasifier consists of combustion chamber, gas primary air inlet with control, grate, secondary holes for proper combustion of the producer gas and vessel support. The major advantage of this type of gasifier was that all the energy available in the fuel was used and controlled the fuel consumption rate with the help of primary air inlet. A reduction in the overall cost for replacing fuel oil and LPG is estimated.
Design and Fabrication of Tadpole Model Solar Powered Tricycle for Physically Challenged
(2018-06-26T06:07:24Z) Dijin, Mathew; Renju, Job P S; Venkat, Naidu G; Rakesh, A
Solar energy is one of the important sources of renewable energy which can be a feasible alternative to fossil fuels. There are many works done in order to incorporate solar energy to everyday transportation including tricycle. However, most of the tricycle developed are expensive and not feasible for developing countries. In this study, a cheaper solar tricycle with more capability of utilizing the solar energy is designed for developing countries. The main problem identified with the existing delta model (2 wheels at rear and 1 wheel in front) for tricycle is low dynamic stability, inefficient braking and poor aerodynamic suitability. Hence a tadpole model (1 wheel at rear and 2 wheels in front) is proposed in this existing study. The model is made to a system in which the power can be obtained from the solar energy . The energy can be obtained externally as a backup when the solar energy is not available. The outcome of this project is a tricycle with a better design and ergonomically well suited for a physically challenged person. Tadpole design will provide better dynamic stability which will avoid slipping of the vehicle and will provide better weight distribution to the vehicle. It will also provide better braking mechanism as tadpole design has two tyres in the front where the weight transfers when decelerating. The tadpole design lends itself better to the aerodynamics tear drop with the correct length to width ratio.
Design and Fabrication of an Artificial Leg Mechanism for above Knee Amputees
(2018-06-26T05:55:09Z) Ganesh, Kumar C; Suhas, Bharadwaj K S; Rahul, M R; Rahul, P
In recent years, there has been a worldwide interest in the improvement of mobility of people with amputations. In spite of significant development of new technologies during the last decade, there exists deficits in motor control because of reduced sensory perception in the amputated leg, asymmetry in leg kinematics in consequence of different leg mass and inertia, energy loss during power transmission from the stump to the prosthesis, prostheses are still energetically passive devices. This paper presents the use of Flex sensor which accomplishes the above tasks with a great degree of accuracy. Flex sensor is a device which measures the amount of deflection or bending. The surface signals picked up from the calf muscles of a healthy leg during the muscle activity are interfaced with a Microcontroller. These signals are processed, analyzed and used to actuate the knee joint of the prosthetic leg. Microcontroller is linked with the DC Servo motor to drive its knee joints, sets up non-linear dynamics and adopts control algorithm to improve the robustness, speed of response and accuracy. During the course of the present work, it is possible to control the rotation of motor of prosthetic knee joint using the sensor signals received from the healthy leg. Hardware and software design of the robotic limb is controlled using flex sensor and arduino controller. The completely designed prosthesis will allow users to walk with a better gait. Microcontroller programming can be done with an ease to suit the requirements.
Study on Assembly Flow Line and Measures to Rectify Interruptions by Utilizing Concepts of Lean Line Manufacturing
(2018-06-25T11:11:27Z) Joyjit, Sarkar; Rishav, Singh; Anchit, Boral; Nandish, G B
The basic principle of lean line manufacturing has its origins from Toyota, Japan. Lean manufacturing involves the concept of reducing the amount of rejections and rework to increase the production efficiency. It also incorporates the concepts of just-in-time manufacturing, standardization, improvement in strategies, continual assessment and improvement of facilities. In a hybrid assembly line, the one which incorporates both automation and manual interventions, the manual worker can stop the assembly line whenever there is an interruption or failure, in order to fix it. Under such situations it becomes a necessity to optimise the process to reduce both the production time and the rate of rejections. Interruption in the workplace are not new in today’s world, however there are more possible ways to stop them. So, we conducted a set of experiments, measuring interruptions in the assembly auto line of BOSCH spark plug at Naganathpura plant Bangalore and we came out with some possible ways to minimize few of them.The studyin this project work includes methods to analyse and re-design the existing system, providing a set of lean line manufacturing concept and methods to locate and rectify the issues that causes interruptions. Requirement for any changes can be determined utilising the lean manufacturing concepts to study the assembly flow line. The source of issue are also analysed and possible modifications in design are suggested.
Design and Fabrication of Internal Pipe Defect Detector Using Visual Method
(2018-06-25T11:00:14Z) Dikshant Dhoj, GC; Nikesh, Rai; Syed Altaf, Ahmed; Shashikumar M, Guttannavar
The project focuses on the development of wireless robot system that can inspect pipeline internally. The goal of the project is to design and fabricate a prototype which can navigate defect through pipelines. Pipelines are typically buried under ground; they are in contact with the soil and subjected to corrosion. Although it is less common, corrosion may also occur on inside surface of the pipe and reduces the strength of pipe. If a crack becomes sever the pipe can leak and in worst case may fail catastrophically. Pipe inspection is especially necessary when one should inspect an underground pipe. Internal Pipe Defect Detector (IPDD) aims to carry out inspection of pipelines through visual inspection with being mobile and powered by battery to make it wireless operated with a controller. Inspection robot has ability to move inside horizontal and vertical pipe along with long complex distance including bend in pipe. Pipe inspection robot can maintain traction between the wheels and pipe surface all the time due to its repositioning mechanism and this enables it to move or transverse vertical pipe section. Expansion and reduction in diameter is encountered in the device. This is achieved by the expansion and contraction of the spring in the device along with Sliding mechanism and four bar mechanism. As spring contracts diameter decreases and when expand it increases. The range of the diameter depends on the movement of transaction element along with the contraction and expansion capability of the spring. Image transmission takes place with the help of camera fitted in the device. This can be visualized in a monitor or can be saved for future analysis. The device is capable of forward and backward motion which is controlled by key pressed from the transmitter. Transmitter transmits data which is received by the receiver and decodes then forward and backward motion is achieved. The device is driven with the help of motor which are connected to battery. The range of the controller depends upon the module used. If Bluetooth module is used it would have a short range, while if Wi-Fi module used it can be used for long range

Pedal Operated Water Purifier
(2018-06-25T09:53:55Z) Nawaz, Jaffar; Steven, John; Jackie, Gupta
This paper analyzes the design of a pedal powered purified water supply device to be used by local dwellers. It works on the principle of compression and sudden release of a tube by creating negative pressure in the tube and this vacuum created draws water from the sump into the pump while rollers push the water through to the filter where adsorption takes place to purify the water. This paper proposes to take on challenges associated with the accessibility and cleanliness of water in developing countries by designing and building a filtration system and sidecar that are portable, durable, and cost-effective. A reciprocating pump will be used to pull unsafe water out of one holding tank, pass through a filtration system, and onward into a clean tank while the rider pedals the bicycle. Water is the most basic necessity for life yet nearly one billion people in the world lack access to it. In many developing countries, people walk many miles to reach a source of water that is not necessarily potable. The functionality of the pump and filter system needs to require as little maintenance as possible. The design must also be user-friendly as the assumption will be made that users will have no experience with any vehicle of this type. Once the design is optimized, materials within the build will be considered to find the most cost-effective method of manufacturing. This design will reduce the labor, cost and weariness caused by transporting and sanitizing drinkable water for use in the homes of villages.

Development of Double Basin Solar Still with the Aid of Latent Heat Techniques to Maximixe Distillate Output
(2018-06-25T07:59:58Z) Harish, R; Lakshminarayana, M; Trishul, V; Vinay, D
This water purification system is designed by contemplating the water shortage faced by the urban areas during summers and the use of polluted lake water by the local farmers for irrigation, while analyzing the economic factors and feasibility associated with this process. The presence of heavy metals, phosphates, nitrates and Escherichia coli in the lake waters of the urban areas render it unfit for domestic use and irrigation. The crops cultivated utilizing these waters are hazardous when ingested by humans and cattle, this may lead to bioaccumulation. The system designed aims at purifying the lake water, solely using solar power and natural filtration techniques. The experiment was conducted at New Horizon College of Engineering, Bangalore, Karnataka (latitude12o93’N longitude 77o69’E). The system uses distillation as the basis for purification of water. The use of a double basin system and black gravel increases the efficiency of the process thereby increasing the distillate output. The peltier system uses thermo-electric cooling to reduce the temperature of the glass which in turn increases the rate of condensation. The electricity required to run the peltier can be easily generated using a solar cell.
