Fontus - mini cooler

Mini Dehumidifier Invention For Cyclists

Today’s topic is making a bottle that can collect water from the air. It’s an amazing invention and is crucial for the use of this assembly where there is scarcity of potable water. Bringing this while touring via bike etc. can prove to be of a great importance.

Introduction:

This is called a “Fontus” and works best in humid weather facilitating it to condense the moisture in air into safe potable water.

The experiment has done to test the efficiency of the assembly and came out to be able to produce 0.5 Liter water in just under an hour and that’s pretty impressive right?

It is estimated that by 2030, 47 percent of the global population will inhabit in water scarce areas.

Integration:

It can be used as an accessory for the bicycle. That would be useful for the long drives and touring where it is difficult to collect the water. It would let you enjoy the “Adventure Trip” at the same time without the worry of water.

Working Of This Project:

The basic principle involved in the process is the condensation of water.

The hot humid air is cooled to the condensing temperature by the use of Peltier module acting as cooler. There is a small electricity source which powers the Peltier module.Fontus mini cooler

The mini cooler is divided into two parts: The upper chamber and the lower chamber.  The upper side is cooled by the cold junction of the Peltier module and the lower chamber gets hotter. This is how Peltier effect works. The lower the temperature or heat removal from the hot chamber the higher will be the efficiency as the upper chamber even gets cooler.

The two sides are isolated from each other. The air enters the bottom chamber with high speed, when vehicle is in motion thus cooling the lower hot chamber.

The condensing surface is larger to get the most possible area with the small space to enhance the condensation of the air. The direct air is obstructed by the perforated air in order to get the max time for the incoming air for shedding its air to the chamber.

The collected droplets then are funneled into a bottle by a pipe. The bottle oriented vertically to take it out of the assembly.

To make this at home you need some knowledge of Engineering. If you are trying to make it by your own or have made already do share with us via commenting in the below comment section.

Dolphin Like Sea Glider

We all have been heard many times in debates and discussions that global warming is responsible for the melting of polar ice. However this is not the only reason for the melting, the swirly eddy currents add to that. The findings are based on the information gathered by the Robotic ocean gliders.

The Findings

Ice sheets of west Antarctica are melting at a faster rate and it is predicted that if it continues with the present rate might raise the sea level by 3 meters. Scientists have been a close eye for many years on the warm water near the coast of west Antarctica and got into conclusion as one of the main reason for the melting of the ice. It remained a mystery for some time on how it is happening. Finally scientists have gathered some crucial information regarding ice melt.

How they got the information?under water dolphin glider

The obvious question that comes to mind is how the hell all the times scientists find the reasons and solids information for the concerned problems? Well, they do research simple.  This time they took help of three robotic gliders which look like the dolphins under the sea.

The gliders are 2 meters in length –around the size of a bottle –nosed dolphin. They were deployed deep down the ocean near Antarctica to measure the salinity and temperature. After two months of research they found that eddy currents, swirls of warm water are the reason, reaching the surface. This leads to the melting of the coastal ice.

Eddies current are actually the instabilities in a medium caused by certain factors. You can imagine eddies as circular motion of the liquid medium forming the whirlpool, a perfect example would swirl formed while mixing the sugar in a cup of tea by the use of spoon, Eddies facilitates mixing. Hence when we talk here about eddies current in ocean that means mixing of heat into ocean water efficiently.

Researchers used ships to gather ocean data in the past, the method being expensive having lots of constraints. However the gliders like this enhances the capabilities of taking ocean samples for much longer time. These battery powered bots are extremely energy efficient.

How Dolphin Gliders do it?

These gliders dive into the ocean like a dolphin. The batteries power a pump that pushes water into a specially designed compartment within the glider. It makes it heavier than the sea saline water making it to sink. When they it needs to come upon the surface, water is pumped into a bladder which is incorporated into the dolphin surface, making it more buoyant and causing to rise.

Each time when glider comes to the surface, it calls the researchers via mobile phone inbuilt device. This allows the researcher to find the dolphin and collect the information it has gathered from deep down the sea.

Further the team wants to adopt a more advanced sophisticated glider to study the Drake Passage. This is a patch of ocean between the southern tip of South America and Antarctica. This narrow stretch of ocean is known for its deep waters coming at the surface. And making it ideal to study the CO2 exchange between the ocean and the atmosphere.

The Project Idea which you can take out of it:-

Well there are lots of researches has to be done inside the ocean and day after day new things come up. You being the engineers can help these researchers by making some new kind of Drones with new sensors. You can make bots that can directly transmit the information in the real time even if the glider fails. As far as college Engineering project is considered, you can make a prototype of it by incorporating batteries and propeller into it.

In case you have money constraints, you can make static model showing areas in it for more advancements. We never know when we become a crucial inventor.

Finally it’s always important to share information with the mates. I would be pleased if you share it in various networking sites. Do comment if you feels like having a potential project idea and loved it.

bionic bird project for engineers

Bionic Bird Project for Engineering Students

Hello friends, your Engineer buddy, have brought you a new project idea for your engineering projects. Today’s idea is world’s first furtive civilian drone. It’s a bionic bird.

The unique characteristic of this bionic bird is that it flies not with the rotating wings like in helicopter drones but uses its wings like a bird in up and down motion to fly. The most interesting is it can fly in a group of the real bird without even making them realize that it’s unreal. This bionic bird like drone is shown attracting other bird and predators.

Following is the demonstration:-

 Construction and working

The bird’s body is constructed with high quality wear resistance foam. The wings are made of the carbon fibres for weight reduction and increased durability. It is incorporated with a Bluetooth 4.0 for communication via smartphone. Soon it would be controlled with an android application too.

There is an on board battery which allows it fly for around 8 to 10 minutes and took 12 min to charge with the egg shaped charger. Presently it does not have too much practical applications but later version would have improvements such as inbuilt HD camera with live streaming, control with a wrist band, and hovering ability like a humming bird. This drone can be operated within a range of 100 meters.

Following is the video showing its internal gear system. The video represented  rotatory motion conversion to reciprocatory motion in  bionic bird.

It is sort of a good toy to play around for some time.

Hope you liked this article and you really loved the concept than don’t forget to share with your friends and amaze them with the bot.

 We are always fascinated with the objects that fly in sky. We have the intrinsic desire to fly like a bird, hovhendo hoveboard, magnetic levitationer like a bug and love adventure related to sky. The researchers have created a hover board which is a combination of a skate board and hover craft. It levitates above ground. A Japanese technology team also demonstrated ultrasonic levitation working in three dimensions.

This is the technology which you normally would see in the science-fiction movies. With this technology, hovering car and trains could revolutionize the world and add a new way to transportation. They called the hoverboard a hendo, a special skateboard. The nonferrous material let Hendo to hover and is conductive in nature. We all know magnetism from childhood that like poles attracts and unlike repels. It is the old known concept behind the technology.

The board has disc shaped motors acting as four engines that create a magnetic field which react with the non-ferrous conductive material producing the secondary magnetic fields. Each field repels the other, allowing the board to hover above the ground. The hovercraft uses magnetic field architecture and only reacts to certain materials such as copper and aluminum. The blue light adds to the aesthetics. The working of the Hendo is quieter. Tough part while making the project was with the balancing, described by Earns haw’s theorem. The theorem state: that it’s utterly tough to balance magnets when they are repelling.

The magnetic hovercraft was restricted in a track for equilibrium. The device is capable of weighing upto 136 kg hovering few cm. above the ground. The Hendo only float above the ground or park made for hovercraft. It cannot float above the water. They are working to get some more advancement with the major goal to levitate the house. Presently 50,000 kilogram train is already running on track like the hover train, Levi train. The cost of such board is $10,000.

In the pioneer’s festival in Vienna, the most advanced flying car was unveiled by the Slovakia based company, aeromobil. The aeromobil 3.0 is the name of their prototype. It has accommodations for two passenger and has length of the limousine. The car make you feel like the luxury sedan. The amazing feature of the car, which makes it advanced, is that it can transform from car to airplane within few minutes and reminds us like a transformer from the film- Transformers. The speed of the vehicle in car form is upto 160km per hour and 200km per hour as a flying aircraft.

Front view makes it look like a car whereas back view makes feel like a private jet.  The aeromobil 3.0 requires 250metres of open field, pavement or grassland to take off and 50metre space to land. When one feel it to fly, just a touch of a button ,it opens its wings like from the side automatically an a large  becomes a small flying plane. It can be kept at home garage just like a car when we are done with the flying.

The company says if one need to buy the car, they must possess the pilot’s license, which is fair enough. We certainly don’t want someone to crash it onto or roofs. Presently only trained pilots are permitted to test the aeromobil 3.0.

volocopter engineer project

Introducing -Volocopter:  final year Major project

Greetings to all the engineering aspirants. One of the strong instinct of human being was always was to fly like a bird in the sky. In early time it was considered impossible but with the evolution of human being and advancement in the technology, we ‘humans’ made that possible and opened the doors of our mind. With that, we believed in us and can achieve whatever we think of. Many of the Engineering students still intrigued with the flying objects and aspire to make them by their own. For them, we have brought one of the idea which you can take and go and for it.The researchers and makers named 18 rotor helicopters as volocopter.

Volocopter Simulation

The experiment of flying the real volocopter is done by the simulation process.  In the simulation, 5 minutes of flight instruction is given to the person, which includes steps for taking off, moving it to front, left, right, etc. The simulation is of the UK city of Liverpool. It mimics perfectly the real world.  The person is allowed to fly it even if he has no flying experience. Developers said that it uses an early version of the easy to use control panel and would form a basis of a much malign concept i.e. the flying car.

Cars that transformed into a flying helicopter are usual approaches and such kind of prototype is already launched by AeroMobil of Bratislava, Slovakia in a technical conference. The major drawback of ‘road able car’ is that it still need an airport for the takeoff and has failed since 1950s. Those are user friendly and still require technical abilities to fly one. Not to forget this point that it would not replace the cars from the roads and help ease road congestion.  What is required a system, which can take a vertical takeoff and system that can fly one point to another strictly.

 

final engineering project idea

However by the end of the year that would be possible with the volocopter. Other researches are in progress like the ‘My copter’ by European developers with the simple yet efficient flight control interface. One is of which is based on a car steering wheel plus the camera with added sensors. That will let the flying cars automatically avoid each other hitting, without the involvement of the user. Apart from this, they are working on flocking software that automatically plots GPs routes and paths to locate a landing spot in bad weather conditions. This project is seen as the key part of a low – congestion transport system in future. Unlike helicopter pilots who take hundreds of hours to master, users will get trained for such fly copters in 5 hours who never have an experience before, developers claimed.

Volocopter Project Specifications

Sources say, within two years, an 18-rotor powered by battery helicopter would be on sale to rich commuters who have dreamed of open skies instead of gridlocked highways.

The Volocopter is incorporated with 18 rotors, each of which is 1.8 meters long, working in counter-rotating pairs around a circular made frame. Though it looks odd, this arrangement means the torque effects of each pair cancel outs and the vehicle just goes up and down, or side to side, by changing the speed of different rotor pairs. The prototype has nine lithium-ion battery packs, each driving two motors that currently allow it to fly for 20 minutes duration. The joystick works in the same manner as a quad-copter remote control panel. If you let go of the joystick, the Volocopter keeps hovering where you left it, developers says.

We hope this article would be helpful to you. In case you have any query regarding the article or want to know some technicalities, please don’t hesitate to ask. We would love to reply you to the most possible way we can. Stay tuned with us for other Project Ideas and Engineering Projects.

Termite-Inspired Robots Can Build Unsupervised

Greetings to all the science buddies. We are always fascinated by the robots and the science behind robotics. Our Hollywood films are too intrigued by the robotic engineering and that is one of the reason they incorporated all they incorporates sci-fi robots and their amazing abilities. The films we can see most of the robots or arterial intelligence are- iRobot, Terminator series, Transformer series, Wall-E etc. and the list goes on. One of the latest works on artificial intelligence and robotics is today’s project. You can take lots of ideal or references to make similar stuffing and become part of the noble cause.

A team of engineers and computer scientists at ‘School of Engineering and Applied Sciences (SEAS)’ and the Wyss Institute for Biologically Inspired Engineering at Harvard University have produced an autonomous robotic construction crew. The most appealing character of the crew is that it requires no supervision. It does not require an eye in the sky, no communication to guide, just simple robots. They cooperated to each other and act intelligently themselves modifying the environment. The team got its inspiration from Termites so they call it the Termite Crew. The Harvard Termite System corroborates that collective system of their robots can build complex, 3-D structures without the want of any central command or prescribed roles. The result their four year hard work was presented at AAAS 2014 Annual Meeting.

Now one obvious query you all must have what can they build so they can make towers, castles, pyramids out of foam bricks and autonomously builds the staircase to reach the higher levels for adding bricks and materials for construction when they need. In the near future such robots could lay sandbags in advance of the flood, etc. and perform construction tasks on Mars and moon etc.

On an Interview with the core faculty member  while discussing the amazing  robotic crew She says “The key inspiration we took from termites is the idea that you can do something really complicated as a group, without a supervisor, and secondly that you can do it without everybody discussing explicitly what’s going on, but just by modifying the environment”  The lead author also  said that most human construction projects today are performed by the trained workers  in hierarchical organization . We all are pretty much aware that when a construction project is started we do have a blue print and plan. the foreman then directs his crew members and supervise them .while in the termites world the queen does not instruct  each individual  member but everyone is aware of  what other the termite is doing and the current overall state of the job they are accomplishing.

termites botes

The curious geeks want to know by now, what is that concept on which this system depends? The answer is ‘Stigmergy’ which is a kind of implicit communication. The bots observe each other’s changes to the environment and acts accordingly. Each individual robot executes its building process in parallel with the others without being aware who else is working in the same real time. This means that the same set of instruction can be executed by ten robots or ten thousand. This system is a perfect epitome of concept for scalable, distributed artificial intelligence. The bots are employed with simple sensors and three actuators.

This system is a plus in contrast to the previous concept where a central controller is needed or an eye in the sky. It guides the whole crew and keeps an eye on them all the time. The system works efficiently if the crew of the robots is small but with the increase in no say- 500, becomes complex and difficult to manage. On the other hand if there occur some problem with the central control, leads to failure of the whole crew system.

Following are some points to decipher about the termite Crew:-

What can a TERMITES robot do?

  • Move forward, backward, and turn in its own place.
  • Climb up or down a step the height of one brick.
  • Pick up a brick, carry it, and deposit it directly in front of itself.
  •  Detect other bricks and robots in immediate vicinity.
  •  Keep track of its own location with respect to a “seed” or brick.

What instructions do the TERMITES robots follow?

  • Obey predetermined traffic protocols.
  •  Circle the growing structure to find the first, “seed” brick (for the orientation).
  •  Climb onto the structure.
  • Obtain a brick.
  •  Attach the brick at any vacant point that satisfies local geometric requirements.
  • Climb off the structure.
  • Repeat.

We, Mech- Ant – Group is also inspired by the working of ants all together to accomplish the task too. We hope this article would be helpful to you. In case you have any query regarding the article or want to know some technicalities, please don’t hesitate to ask. We would love to reply you to the most possible way we can. Stay tuned with us for other Project Ideas and Engineering Projects.
