 Abstract

A crop cutter is a machine that uses sliding blades to cut a lawn at an even length. Even more sophisticated devices are there in every field. Power consumption becomes essential for future. Crop cutter is a very useful device which is very simple in construction. It is used to maintain and upkeep lawns in gardens, schools, college's etc. We have made some changes in the existing machine to make its application easier at reduced cost. Our main aim in pollution control is attained through this. Unskilled operation can operate easily and maintain the lawn very fine and uniform surface look. In our project, crop cutter issued to cut the different crops for the different application. Today, Agriculture especially in India need to concentrate in some aspects such as how to increase the productivity and profit, how to reduce the cost and how to solve the problem comes from workers. To overcome these, a new motorized cutter is fabricated specially for cutting various crop varieties during the time of harvesting and named as an ultraportable crop cutter. It comprises three criterions such as "easy to fabricate, low cost and light weight". With this Ultraportable Crop Cutter, the entire problem can be solved easily. There are some procedures involved in fabricating this device such as fabricating the prototype using suitable material and test the functioning of this machine. So the objectives are to fabricate and test the performance of the prototype of a motorized crop cutter for harvesting the crop.

 Abstract

Considering the energy security concern for and commitment to a 'Low Carbon Growth Strategy', the 12th Five Year plan of the country included plans to ensure sustainable development of the power sector. Due to the RE impetus an increase in the development of medium to high density wind and solar farms in India is expected. In this scenario it becomes important and necessary to revisit the impacts of RE projects in the neighborhood where these projects are coming up. Thus, this study is commissioned by MNRE to assess the environmental and socio-economic impacts of RE projects in India, particularly from solar PV and on-shore wind farms in hybid mode.Hence to test this we have tried to fabricate a hybrid solar cum wind mill power plant model.

 Abstract

This system is very beneficial in areas where there is high risk for humans to enter. This system makes use of robotic arm as well as robotic vehicle which helps not only to enter an area involving high risk but also to pick whatever object it wants to. The system also includes night vision camera which will not only allow viewing whatever will be recorded in day time but also during night. The whole system is controlled via RF remote. The system sends commands to the receiving circuit mounted on the vehicle through push buttons. The receiving circuit involves 8051 microcontroller and a receiver which receives commands sent by the transmitting circuit. At first the system is set to control the movement of vehicle. In order to set the system in a mode that operates the arm. At first the user needs to press the push buttons for moving the vehicle in whichever direction it wants i.e. forward, backward, right or left direction. In order to make the arm movement, the user needs to long press the forward and backward push buttons. Thus this system makes use of camera, robotic arm and robotic vehicle to enter a high risk involving area and also to pick, move and drop an object as well as record the place wherever the system goes and later view it for future reference.

 Abstract

Conventionally the feeding of the cattle is manual which is time consuming. In this project, an automatic cattle feeding system is introduced where food feeder follows the path through a pre-determined distance and places the feed to the cattle by the side of the feed fence. The prototype is developed using screw conveyor mechanism for the operation of feed mechanism with certain time space. The motors are interfaced to operate in either direction. A belt conveyor is operated by a DC motor to feed the cattle at certain time space. This mechanism is basically controlled by motor

 Abstract

Pedal powered washing machine (PPWM) is a low-cost washing machine made up of easily and readily available scrap parts in daily life. It is a machine which generates power through pedaling and with a drive mechanism, converts the pedaling motion into required rotary motion of the drum, innovation lies in simple design, without use of inexpensive parts. We intends to directly address the problems faced in washing clothes, and thus have developed a new design for easy effort in washing, rinsing and drying clothes. In our country where approximately 70% of population is living with very poor economic status those people cannot have a washing machine because of cost constraints. The present work is an attempt to develop a concept to make a cloth washing mechanism which can meet our requirement of above mentioned 70% population. PPWM is completely new concept, which in its one laundry cycle does washing, rinsing and partial drying of cloths similar to that of automatic washing machine available in market

 Abstract

This paper discusses innovative technology in terms of various ways to irrigate agricultural land using solar power. Agriculture is the central heart for the nation and farmers. Nowadays Agriculture is decreasing day by day because of reduction of water and it consumes more electricity and loss of water in many fields like irrigation fields here because the overflow of water in irrigating land results in loss of water and also it will make plants decay. To control this cause we are using renewable energy by means of solar panels along with a pump and monitoring control system with four sensors. With the help of this system we are able to reduce, save and consumption of water will be in the limit without loss of water. This system performs automatically because an automatic monitoring system is provided.

 Abstract

This new feature deals with the actuating of the bus doors automatically using advanced timers, relays & specialized microprocessors to assist the driver to close these doors without closing in on the passengers effectively trapping them between powerful pneumatic doors as opposed with the existing manually operated technology where these accidents are prevailing as happenstance all-around and the country and the driver has to react to it manually, after realizing what is happening to their passenger because of a seemingly extenuated problem. Thus adding this piece of hardware to an existing component not only improves safety and assurance to property and personnel but takes off one more thing the driver has to worry about extensively while driving a multi axle vehicle carrying more than fifty passengers. This also allows passengers to have more feasible egress during an event of any emergencies including but not limited to smokes, collisions etc. After many avenues of analysis it is submitted for the future reference and use of next generation vehicles.

 Abstract

Nowadays, automobiles consume a large number of fossil fuels. However, the consumption of fossil fuels has brought many serious environmental problems, such as global warming, ozone layer depletion and fine particulate matter. To avoid such environmental problems, renewable energy has been applied to automobiles. An air-powered engine of a renewable energy vehicle is introduced. To lay a foundation for the optimization of compressed air engine (CAE), a physical model of compressed air engine (CAE) is established with cam which controls compressed air charge or discharge cylinder. To obtain performance of the CAE, a prototype CAE system is set up. The output torque, power and efficiency are obtained through experimental study. The results show that the prototype of CAE has a good economic performance under low speed and when the supply pressure is 2 MPa, the maximum output power is 1.92 kW; the maximum output torque is 56.55 N?m; and the maximum efficiency is 25%. This research can be referred to in the optimization of air-powered engine.

 Abstract

This project harvests energy from speed breaker by making gear arrangement and using electronic gadgets. Large amounts amount of electricity can be generated saving lot of Money. And if implemented will be very beneficial for Government. When vehicle is in motion it produces various forms of energy like, due to friction between vehicle's wheel and road i.e. rough surface HEAT Energy is produced, also when vehicle traveling at high speed strikes the wind. The principle involved is POTENTIAL ENERGY TO ELECTRICAL ENERGY CONVERSION. There is a system to generate power by converting the potential energy generated by a vehicle going up on a speed breaker into kinetic energy. When the vehicle moves over the inclined plates, it gains height resulting in increase in potential energy, which is wasted in a conventional rumble strip. When the breaker comes down, they crank a lever fitted to a ratchet-wheel type mechanism (a angular motion converter) which in turn rotates a geared shaft loaded with recoil springs. The output of this shaft is coupled to a dynamo to convert kinetic energy into electricity

 Abstract

A sieve is a device for separating wanted elements from unwanted material or for characterizing the particle size distribution of a sample, typically using a woven screen such as a mesh or net. This project focuses in design, fabrication of the mechanical part of machine and the system of the wind operated sieve machine. To achieve this project objective, this sieve machine body structure and mechanical system needs to concern some other criteria such as strength, safety and ergonomic design. Depending on their size the individual particles either pass through the sieve mesh or retained on the sieve surface. There are different machines that are being used for sand sieving processes. In our project the process will takes place automatically. Thus, the time consumed during the whole process is reduced
