MAV Flapping Wings Using Repelling Magnets Concept

One of the holy grails of designing micro air vehicles or MAVs is to build a prototype that mimics a flying bird or insect. Why? Simply because evolution is the best designer of all, those designs that work flourish, those that don’t, well those species perish. Yes, that is the harsh reality of nature, but we can learn from its incredible time-tested research and development as each iteration serves a specific niche allowing for growth of the species.

Okay so, an MAV is a very small robotic airplane or flying device, yes, also built to serve a specific niche. In most cases built by robotics teams trying to prove concept, or their ability to use biomimicry to copy some sort of insect or bird. The ultimate goal would be to use these devices to do surveillance as the proverbial ‘fly on the wall’ or camouflages as a biological equivalent such as a bird.

This turns out to be a little harder than it looks, but not impossible at all, in fact a few robotics teams have conquered the challenge and a few small defense contractors have pulled it off. Today you can buy small remote control bird-like models and fly them around to entertain yourself for kicks. Now then, often I myself consider things such as muscle memory materials and other strategies that might assist in the flapping of wings. Thus, came up with yet another concept, using repelling magnets on the wing tips of a small MAV.

How would this concept actually work? Well, using repelling magnets on the wing-tips of a flapping-wing micro-air vehicle would cause the wings to fly apart at a good rate of speed. How this would work is somewhat a unique concept. You’d hold the wings together between your thumb and fingers then let go and the wings would repel down until they hit again at the bottom of the stroke, once again repelling until the wings hit on the up-stroke and so on, flapping along. The mathematics for the best Reynold’s Number and use the Navier-Stokes equation would be employed to ensure the best possible efficiency.

In looking at other flapping wing designs, they often use little motors and gears, perhaps such strategies too could be employed to see that the system continued to operate and never reaches equilibrium, as is the problem with magnetic ‘free energy’ concepts which look great on paper but never actually come to fruition.

3D Printing: The Near Future & Market Opportunities Explored

The 3D printing process was invented by Chuck Hill in 1983, named, as ‘stereolithography’ as a technique for constructing solid entities by sequentially printing thin films of ultraviolet material over one another. This technique laid the foundation of present scenario of 3D printing. The modern definition of 3D printing can be defined as an additive engineering process to generate a physical entity from a digital source or design. Today, there are various 3D technologies and material available in the market, but all follow the same standardised procedure: a solid material from a digital design by adding consecutive layers. A typical 3D printing initiated with a forming of digitalized design file of a physical entity. The next step varies with technology and material used, commencing from system printers to melt the material and place it down onto printing platform. The time is highly dependent on the printing size, and often post-processing events. The common printing techniques include fused deposition modelling, stereolithography, digital light processing, selective laser sintering, polyjet and multijet modelling, binder jetting, and metal printing (selective laser melting and electron beam melting). The materials for printing varies by printing options, ranging from rubber, plastics (polyamide, ABS, PLA, and LayWood), ceramics, biomaterials, sandstone, metals and alloys (titanium, aluminium, steel, cobalt-chrome and nickel).

The 3D printer is advantageous as they offer construction of complex designs which cannot be produced by traditional methods, customization of products with no supplementary detailing or tooling, and no additional pricing, and creating a hope for entrepreneurs or designers in cost effective production for market testing or other needs. In addition, the traditional methods for manufacturing an entity generate a huge amount of waste of raw materials, for instance, bracket manufacturing lavish nearly 90% of the raw material. On the other hand, 3D printing manufacturing process involve minimal wastage of material and can be recycled in the next cycle.

However, the concept of 3D modelling often associated with drawbacks such as high cost of large production, restricted strength and durability, and lower quality resolution. Moreover, there are more than 500 3D printing materials available in the market, most are made from plastics and metals. However, owing to rapid technological advancement, the number of materials is increasing briskly comprising wood, composites, meat, chocolates, and so on.

As exemplified by public sources, by 2027, one tenth of world’s production will be 3D printed. Consequently, the cost of printers will drop from $18,000 USD to $400 USD in upcoming 10 years. Therefore, various companies have started their 3D printed production such as dominating shoe companies as well as in aircraft constructions. Evolving technology will create a scenario where smartphones were fortified with scanner allowing to build anything at home, for instance, China has created a complete 6-story building by using 3D printing technology.

The 3D printing has diverse applications in the fields of medical, manufacturing, sociocultural, and industrial. Based on manufacturing applications, the field is divided into agile tooling, food, research, prototyping, cloud-based additives, and mass customization. Based on medical application, the field is distributed into bio-printing devices and medicines. For instance, in August 2015, 3D printed surgical bolt device, named, ‘FastForward Bone Tether Plate’ was approved by Food and Drug Administration (FDA) for the treatment of bunion. In addition, in May 2017, the researcher of Max Plank Institute for Intelligent Systems, Germany developed a micro-machine, named, microswimmers, by using 3D printer technology of Nanoscribe GmBH, for precisely delivering drugs to the site of infection and can be controlled inside the body. Various industries have adopted 3D printing technology for manufacturing their products. For instance, Airbus SAS, France declared that its product, Airbus A350 XWB contains more than 100 3D printed components. The astronautical industries have developed a 3D printer through the collaboration of NASA Marshall Space Flight Center (MSFC) and Made In Space, Inc. for printing in zero gravity.

If Our Future Is Digital, What Will Be the Biggest Advance?

Our world is full of screens. We keep them in our hands, purses and pockets, next to our beds while we sleep, and surround ourselves with screens on our desks and counter tops. What if all our screens, everywhere, were a two-way networked system that turns the Earth into a digital room with everyone in it? What if that networked system brought everyone the world’s best services, resources and knowledge based on what we do, as a normal part of everyday life?

If your future devices were continuous and serve you, your control over all your devices, and the continuous digital world they could open for you, could expand exponentially.

You switch between multiple screens. When you leave your old screen it stores “where” and “who” you are, then turns off. Your new screen recognizes you, turns on, retrieves “where” and “who” you are, puts you “there.” It is truly automatic.

All sorts of things are in front of you – with you. They could be people, services or places. They could be apps or software, digital content (books, TV shows, movies, music, recorded videos and more), games or live video from events worldwide. They could even be other devices and sources you control remotely.

Your digital life will always be on, always open, always yours. You’ll live in your “Shared Planetary Life Spaces.”

You combine anything into the digital “shared space” you want to inhabit, until you switch to a different one. Then switch again.

In fact, it’s so real that your “shared spaces” move with you across your screens, and become one of your realities. It’s the digital world you choose, where you can live. Always ready for you to use in whatever ways you want.

Much of your life is already you-centered. Next your digital life will let you become the person you’ve always dreamed of becoming.

Your digital life is a real life. Wherever you really are.

For billions of people all across the Earth, yesterday’s world isn’t succeeding well enough or fixing problems fast enough. Too many are stuck, educated, aware, capable and connected – yet locked in a limited future instead of free to soar.

Isn’t it about time that your reality was yours, continuous and under your control?

Something else future technology will offer is called Active Knowledge. What if the best knowledge, tools, resources and opportunities to succeed could be delivered as part of what we do every day, as we use our screens? Everyone could become able to perform as well as the best in the world.

Then, with a universal interface, everyone could surpass the physical world’s limits from anywhere. It won’t matter whether you’re in Silicon Valley or a small village in Africa.

You will be a global person who connects everywhere. The whole world and its best knowledge and resources will be local to you, at your fingertips, under your control.

Everyone could rise to the top.

Is it time to expand today’s limited devices, and expand today’s limited world? Should we begin a digital world where everyone could choose to be their best, where greatness could be normal?

This won’t happen overnight. But unlike any generation before in history, we know how to design and build our dreams.

One day greatness will be in our grasp. But rather than waiting, can we reach it now?

Holographic Traffic Cops of the Future

Have you ever seen a traffic cop standing in the center of the street when the power goes out directing traffic or after a big game directing traffic to keep the flow moving? Have you ever considered how dangerous this really is? Have you ever stopped to think that someone not paying attention or talking on their cell phone could at anytime mow over the traffic cop? Hey now be nice, as you probably deserved that last ticket, so don’t go there. You are evil I cannot believe you just thought that?

In any case my point is this, with the up and coming future advances in Holographic Technologies, which are getting closer to becoming reality we may soon be able to design a Holographic Police man to stand in the intersection so you can run him over all you want; no harm, no foul.

I propose we put holographic projectors in the police cars to display the 3D or 4D in Virtual Reality, just like what Microsoft is planning with the next generation of our 360 X-Box Video Games in our living rooms. The system will run off the police cars extra alternator for juice and will not need the power grid, so if the power is out after a severe thunderstorm, Hurricane or Earthquake, the police car can drive up point it, turn it on and restore the flow of traffic without risking his life. This will insure an end to the chaos and smooth traffic flows and prevent injuries. Because as a taxpayer the last thing we want it to pay for medical bills from a flattened policeman. Think on this.
