Design and Fabrication of Pesticide Spray Machine using blue tooth technology[ ]


Agriculture has a predominant role in our day to day life. Spraying of pesticides is an important task in agriculture for protecting the crops from pests. The conventional methods were person carrying a sprayer and manually actuating a lever to generate and pump the pesticide through a tube or a mobile vehicle carrying an inbuilt compressor and sprayer unit. Another major drawback in human operated systems is that the operator is exposed to the harmful chemicals while spraying which is extremely detrimental to operator’s health. A battery powered semi automatic pesticide sprayer model consists of a re chargeable battery, two DC motors, pump, container, microcontroller and Bluetooth device which is operated by a wireless remote( range of 30 to 50meters) which runs on power source as a DC battery(12V, 9.5Ah). The capacity of the container in the sprayer was designed with 4 liters capacity for an uninterrupted operation of 10 minutes with the discharge rate of 0.556 lpm. Analysis of radiation data from Bangalore showed that the sprayer can be best operated during 9 AM to 5 PM. The vehicle is powered using an onboard battery powered which runs down the running cost. Besides reducing the cost of spraying, there is a saving on fuel as well. The farmers can do the spraying operation without human interference thus protecting them from noxious chemicals.

CONVEYOR [ ]


Spherical robots, sometimes regarded as polar robots, are stationary robot arms with spherical or near-spherical work envelopes that can be positioned in a polar coordinate system. So, these robots are more sophisticated than Cartesian and cylindrical robots, while control solutions are less complicated than those of articulated robot arms. This may be the reason why sometimes they are used as a base for robot kinematics exercises. Also, it should be noted that spherical robot type takes a significant spot in robot history, as some of the first robot arms can be counted into this type. Modern industrial robot arms kind of evolved from spherical robots and are sometimes regarded as this type, as their work envelope often is sphere-like as well. Polar Robots, or spherical robots, have an arm with two rotary joints and one linear joint connected to a base with a twisting joint. The axes of the robot work together to form a polar coordinate, which allows the robot to have a spherical work envelope. Polar Robots are credited as one of the first types of industrial robots to ever be developed. Polar robots are commonly used for die casting, injection molding, welding, and material handling & in medical field for Lab analysis & testing.

LEAN MANUFACTURING: ANALYSIS OF VSM, OEE AND IMPLEMENTATION OF 5S[ ]


Manufacturing is one of the prime sectors that has kept the world running for almost three centuries now. The technology has grown skyrocketing. As the technology became more advanced the customers demand increased and this in turn put a hit on many industries on their working schedule. Time I the key factor here. As to this, to meet the customer requirements in the given time many scholars and industrialist came up with different techniques and one successful method was lean manufacturing. Here in this project we have implemented lean manufacturing to a cell through machine analysing and OEE monitoring and mapping the key process that defines the pay for the job. Initially we had noticed that the part process was not monitored regularly and the part environment was not maintained. We have taken that into consideration and implemented 5S concept that will improve the cell efficiency.Value stream mapping is a concept that gives details about all the process that a part undergoes during the machining operation and makes it easy to identify all the value-added and non-value-added process so that we can make changes with regards to them. These concepts are time consuming; they are not a fast go process. they are implemented one by on which improves the overall factory efficiency step by step. We have taken all the parameters into consideration and have come up with a few of the best possible outcomes that can increase the production speed whilst maintaining the quality and customer satisfaction.

Hot corrosion experiments were done on the coated and uncoated materials under a salt environment of 40%Na2SO4 and 60%V2O5 at 700°C. Thermogravimetric cycles of 1 hour heating and 20 minute cooling was followed for hot corrosion study. After each cycle weight measurement was carried out. It was observed that the coated sample is more resistant to hot corrosion than uncoated samples. Gravimetric analysis indicated that the sample weight gain was following a parabolic relationship with time. A damage mechanism is discussed for the hot corrosion damage of the samples. Presence of high level of chromium in HVOF sprayed coating imparts improved hot corrosion resistance at 700°C, in a molten salt environment of Na2SO4 + 60%V2O5. Based on the thermogravimetric data, the relative hot corrosion resistance is more of the WC/Co+NiCrBSi coated and compare to uncoated materials. Also both coated materials are shown more corrosion resistance comparing to uncoated materials.

Design and Fabrication of Power Generation unit From Railway Track[ ]


In this project we are generating electrical power as non-conventional method by simply running train on the railway track. Non-conventional energy system is very essential at this time to our nation. Non-conventional energy using locomotive path needs no fuel input power to generate the output of the electrical power. The main aim of the concept is to utilize the train crossing time on a railway track. The power is produced by the railway track power generation equipment. Here the train flat is rubbing the roller held on the axle with the gear set which rotates the generator to generate electricity during the roller rolling. The roller will be rolling for the entire length of the train moving on it, and the energy generated will be stored in the battery and also showing the output by glowing a set of 10 LEDs. The stored energy is shown by glowing a set of street lights.

Design of Hydraulic Fixture for Machining of Automobile Component[ ]


Fixture is a work holding element which is used to hold the work part firmly during the machining operation time & also helps in clamping and de-clamping the workpiece during the loading and un-loading of work part so as to not harm the work part and fixture elements during the machining operation. Pitman Arm is very important part of Steering system. It should be accurately machined with the given acceptable tolerance limits. At present scenario productivity and economics of machining workpiece in large quantity is greatly affected with the work holding devices such as fixtures. Fixture reduces the production cost and interchangeability of machined workpieces. The design of fixture is done by using software SOLIDWORKS 2019. The purpose of the Hydraulic fixture is preferred it reduces the cycle time and increases the production rate with accuracy & precession of the product being produced. The main purpose of a fixture is to locate and hold the workpiece during the operation, to increase the quality and production rate & reduce the production cost.
