The Automated Guided Wheelchair I have proposed allows any wheelchair user to be guided to a desired location on his own, as long as the building itself is adopted to the novel system. Unlike the state of the art, where no automation exists for guiding a wheelchair in modern buildings, this allows the owner of the least sophisticated wheelchair to explore public buildings with more ease than a normal person. In this project we intend to implement a working prototype, which fulfills the fundamental functions of the system. It can be further customized to the needs of system owners.

Our proposed solution empowers specialized robot cists to contribute software components that can be integrated into complete real-time systems. The ...

Brushless Direct Current motor (BLDC) is widely used for Ebike applications. However, even with BLDC motors widely used in electric vehicle, there is still room for improvement in terms of torque density of the machine. The magnetic flux generated by permanent magnets at the rotor section is fixed and can’t be increased.

Designing a machine requires understanding the operation of the machine that acquired for several situations.Tractive study is very important as we are able to analyze and predict the actual speed of the machine in the vehicle in real world environment that have many types of road conditions.There are 6 conditions faced by the electric vehicle especially electric bike which are early start, normal speed, acceleration, high speed, ...

The proposed approach present the development of a computer tool that allows, in the first phase, the modeling of the electric vehicle power chain. This phase is based on a library developed under the Matlab-Simulink simulation environment. This library contains all the components of the power chain; it offers the selection of the desired configuration of each component. In the second phase, the tool solves the autonomy optimization problem. This problem is resolved by a program based on genetic algorithms. This program permits to optimize the configuration parameters maximizing the vehicle autonomy of the chosen chain. This tool is based on a graphical interface developed under the Matlab simulation ...

Gear systems are one of the oldest and most iconic forms of engineering. They have been studied for so long and by such great minds (Archimedes, da Vinci, etc.) that breakthroughs are rare. Mainstream technologies include the Cycloid (circa 1970), Strain Wave (circa 1950), and Planetary (circa 100 BC) drives. The Orbitless (pat pend) drive is the first new low-ratio drive since the Planetary which shares many features such as torque splitting and co-axial drive shafts that spin in a common direction. However, it has advantages such as lower production cost and lower internal speeds leading to much higher efficiency and longer bearing life.

Orbitless and Planetary drives are mechanically very similar. Both have a sun gear (the input), ...

There are three problems related to food safety and pathogens. The first problem is that 80% of food borne illness and 56% hospitalisations and death in U.S. have occurred due to an unknown pathogen. The second problem is the detection method (RAPID-B and BAM 4a) currently been used is extremely slow. The BAM 4a’s time to final result is 48 to 56 hour. The third problem is climate change and global warming. Weather phenomenon such as rainfall, wind and sun are critical factors in food production. Any undesirable alterations to these result in growth of pathogens.

The machine that I am trying to build would detect food pathogens at the last stage i.e. just the stage ...

The objective was to design, fabricate and investigate the working of Pedal Driven Hacksaw (PDH). PDH is working on Slider Crank Mechanism. The experiment was done using PDH and plywood, hollow and solid cylinders, PVC pipe etc. Work pieces... The hacksaw is connected with the reciprocating rod. By pedaling the bicycle the reciprocating rod moves to and fro, the hacksaw will be moving with the rod. The plywood, hollow and solid cylinder, PVC pipe etc. to be cut is placed under the hack saw. Thus the plywood, hollow and solid cylinder, PVC pipe etc. can be cut without any external energy like fuel or current. The results indicate that the PDH had given better, accurate and faster cuts when compared ...

For small scale workshops, it would be costlier to buy & install huge machines which would be suitable for performing singular & precise operations alone. Moreover, in these small scale workshops, job type or batch type of production process is carried out, which always insists the need for developing a multiplex prospect machine, which paves a way for doing these operations & production processes in an economical manner. The portable hybrid powered intelligent special multiplex prospect machine consists of mechanisms for five different tools for performing diverse operations including drilling, grinding, sheet (including plates & switch boards) cutting, shaping and power saw machining and powered both by means of electricity & solar panel, fitted together with height adjustable & ...

The Pulsed DC magnetic engine is circular in design with fixed magnets on the outside of the centre wheel that runs on a bearing. There is an outside housing that holds the pulsed DC magnets one to oppose every fixed magnet, the engine operates off the rule like poles repel so when just before crossing over of magnets the outside pulsed magnet is fired to repel the inside magnets on the rotor wheel which are permanent. So the outside magnets are pulsed magnets repelling the wheel in the direction depending o te fire angle of fixed and pulsed magnets intersect. This gives circular rotary motion happening, this motion can be used to drive a generator on the output to ...

PROBLEM DESCRIPTION:
Nowadays, mobile phones were used by people all around the world. Think a moment while you are out somewhere and your mobile battery is too low. We need to rush to the nearest shop for charging or somewhere else in search of power socket. In this new era, there are many technologies have been arising today. Think if there is no electricity, then there should be some alternative methods to charge our mobile phones. More number of projects has been arising on this latest mobile phone charging technique. Many solutions have been proposed with the help of piezoelectric crystal, solar energy from sun and also by using wind power, sound energy, human body heat, and ...

Recycling some products becomes somewhat hit and miss because of volumes and large enterprises such as McDonalds make conscious efforts to improve their recycling issues.

This idea is based around that restaurant's colorful packaging and is as applicable to other places with similar disposal issues.

It is a high tech semi automated proposition which (over time) can migrate to full automation as the technologies involved mature with the use of the system.

Basically adaptation of machine vision technology detects the color of the product in the first instance and operates gates which segregate material by color into collector bins which can then be sorted into material types for recycling.

Sorting by color is more readily accomplished than reading barcodes ...
