The global population is growing at a compounding 1.3% rate. Society has begun to identify and work toward the need to maintain resource sustainability. A conglomeration of high school FIRST robotics teams will resolve these concerns with an automated renewable energy powered electric tractor, The Automated G. This solution will enable new agricultural production capabilities well suited to sub-Saharan Africa.
Innovation: The Automated G runs autonomously via an Arduino microcontroller, which can be activated at a click of a button. The conversion kit guides the tractor through a special form of GPS, called Real Time Kinematics (RTK). This allows the Automated G to have centimeter accuracy, which prohibits over-planting. Through the collision avoidance system and the lack of ...
Automated Software System For The Simulation Of Arcing In Spacecraft On Board Power Electronics Equipment
In our project, we propose an innovative software solution to the problem of electrical arcing risk prediction in high-voltage on-board electronic equipment intended for long-term self-contained use, like spacecraft conditions. As modern on board equipment is not vacuumed the appearance of arcing leads to considerable damages due to high energetic output from arcs. In spacecraft, this problem has been actual since 1995 when Boeing Satellite Systems offered the BSS 702 platform with high-voltage bus connected to 100 V stabilized power source. Possible further increase of operating voltages (e.g. due change in standard) will only escalate the problem.
Arcing simulation is a monumental challenge because it represents an attempt of numerical solution to the multiscale discharge plasma problem. The main ...
How does it work?
All vending machines consist of two major parts: electrical and mechanical. Initially the customer swipes his/her identity card containing their unique code. This card is scanned by the RFID reader; if it is accepted then the electrical interface consisting of 8051 microcontroller, regulator 7802 and 7812 etc. sends the signal to the motor controlling unit and the motor which is shafted to the power screw starts rotating. This rotating action moves the book holder near the suction cups placed at the top end. When the book approaches the suction cup the vacuum pressure actuates in the suction cup and the book is separated from the stack. This stopping action is due to the presence of ...
In every automobile, the function of the headlight is to illuminate the road ahead from a safe distance. At the same time, it should cause minimum discomfort for drivers coming from the opposite side. In order to achieve this, in every automobile a dip beam is provided in addition to high beam. But as the eyesight varies from driver to driver, many drivers go for more powerful headlamps instead of company fitted headlamps. Manual beam shifting is not being done satisfactorily due to variety of reasons, which includes sheer physical strain involved in operation of the dipper switch hundreds of times every night. Manual beam shifting also requires cooperation of vehicles coming from the opposite direction. The situation gets ...
In a developing nation with a large population, the agricultural sector has its own importance in terms of revenue and food security. Modern methods of farming are not economically and technically feasible with small farms in the country side. The proposed economical product facilitates the farmer by providing automation in spraying the fertilizer on their crops in the farms, increasing the productivity with reducing the working time and effort of manual operation.
Silent features of automatic fertilizer sprayer:
• With the use of ultra-sonic sensor and battery operated pump, given system automatically starts spraying the fertilizers in crop/plants presence and consequently switch off in their absence, thus minimizing the wastage.
• Well placed nozzles helps in uniform spray of ...
NAME: Automatic Lifting Squatting Toilet
PROBLEM SOLVED: Hemorrhoids, hard stools, constipation

Recent studies have shown that this position is associated with a number of health problems.
1. According to an Israeli study published in a journal called “Journal of Medical Sciences,” the squat while emptying your bowels is a main cause of diseases such as:
“The frequency of intestinal diseases (hemorrhoids, constipation, inflammation of the appendix, polyps, ulcerative colitis, irritable bowel syndrome) is similar among white men in South Africa and the peoples of the rich Western countries. In rural areas with style of traditional life, ...
Growing demand of energy is almost everywhere, leading people to think of using it more efficiently. In this regard, we are proposing the auto-light unit, which has many pros over the existing similar products in the market.
Above mentioned PIR sensor based automatic light, senses any movement within 7 meter radius range. Take an example of a corridor, when no person is present, respective light will be in off mode. Now, if any person passes by and comes in that prescribed sensor range, his movement will activate the system and thus light will switch on till that person presence. Switching OFF action can be delayed using the incorporated timer in the same unit. Hence a ...
Over the past ten years there has been an enormous increase in road accidents, where millions of people left their souls on the roads and it’s due to speeding and avoiding safety gear like seat belts.
So to avoid this we designed smarter and intuitive technology. Our aim is to save the driver using the smart technology. In most of the cases drivers ignore putting on the seat belt which leads to major injuries and even death in accidents. But to avoid such problem we are implementing a car seat belt locking ignition system which acts as a main key to start the car.
Another major cause of accidents is speeding, due to not considering the speed limit ...
Automotive Brake Vibration and Squealing Suppression Analysis
Methods in Simulation Design Stage
The brake vibration and squealing problem has been investigated from its occurrence mechanism to systematical analysis method by my group since 1984. The brake system eigenvalue matrix is a non symmetric one due to its frictional coupling parts. So the mismatched system structural design parameters lead to double conjugate complex eigenvalues. The positive real part of complex eigenvalue means that brake system is unstable with the negative damping and self-excited vibration can be occurred, that is the brake vibration and squealing phenomenon.
Our study established a systematical analysis method to identify the most important substructures and their design parameters that should be modified to suppress ...
The ideal Automotive Waste Heat Recovery (AWHR) system needs to be compact, cheap to mass produce and ultimately provide an efficiency improvement that significantly outweighs its cost.The proposed AWHR system operates on a novel heat cycle termed the SLFB cycle and is capable of being produced cheaply with currently available mass produced components.
The SLFB Cycle
The SLFB Cycle is an augmented version of Power Flash Cycles such as the Trilateral Cycle (TLC). In a conventional power flash cycle, an expandable vapour is generated through "Flashing." However, the liquid or unflashed portion which possesses a significant amount of heat energy is discarded as it cannot contribute to expansion work. The SLFB Cycle harnesses this energy by inducing multiphase ...
