Remote controlled aircraft


This mechanical engineering project is about the construction of a flying model of an air craft controlled by a remote control. The materials for construction include light weight materials like wood, plastic and foam.

The tasks included in this working project are:
1. Building the body of the RC plane.
2. Building the RC plane controls.
3. Building the Electronic controls.
rc airplane controls
The four primary controls of an RC plane, collectively called control surfaces, are:

1. Throttle
2. Elevator
3. Ailerons
4. Rudder

The flight of the plane is directed by the movements of these control surfaces. The control surfaces are controlled by small servo motors which are in turn controlled using the remote control.

Even when the plane is made it is not easy to control it without crashing your model several times. So it is better to take a flight video each time you try to fly it, so that if the model is destroyed beyond repair, you may be able to present the video during your project evaluation.

Talking Robots with Lego Mindstorms



From the days of "Small Wonder" TV show , I always wanted to have one robot which can talk and response just like human.To build one as Robotic Project is really interesting. This project is going to be very interesting and challenging because our robot requires not only speak capability but should have artificial intelligence to learn from its surroundings.

Architecture for talking robots consists of four main modules:

1) Dialogue system
2) Speech client with speech recognition and synthesis capabilities
3) Module for infrared communication between the PC and the RCX and
4) the program that runs on the RCX itself.

Automatic parallel parking cars

What is Automatic Car Parking ?

Automatic parking is an autonomous car maneuvering from a traffic lane into a parking place to perform parallel parking, perpendicular or angle parking.


What's the importance of this topic?

Parking is one of the challenging thing for humans in Car Driving. Even though , lot of solutions available for smooth and safe driving such as car collision avoidance system, but very less focus is given to the the automatic parking system till recently. Although,many cars are now available with this feature such as Toyota Prius , still there is a long way to go.

For Whom :

Mechanical, Electrical, Electronics and Computer Science , almost all branches engineering students.

Level : Difficult


It is not an uncomplicated task to build up automatic parking expertise for a car. First of all, the car must be able to sense the surroundings, to find a free parking space and to detect obstacles in the car park.
Secondly, it should have the capability to plan the movement itself from the input of sensitivity system.
Lastly, it should be able to go after the premeditated motion sequences and to make sure that a goal position is reached, regardless of noise and errors.

The Fuel Energizer

The Fuel Energizer is a frequency resonator that uses Neodymium Super Conductor Magnets, which break and then realign the hydrocarbon chains in the fuel passing through the fuel line of your vehicle. The magnetic field created by the Fuel Energizer ionizes the fuel being fed to the engine, which itself produces a more complete combustion, maximizes fuel economy, improves fuel efficiency and reduces polluting emissions.

By installing these Neodymium Super Conductor Magnets close to your carburetor/injection system, your vehicle will start to feel the result of the Resonance frequency of the Neodymium Super Conductor Magnets and by making the fuel flow smoother your engine will run more efficiently. The way to ensure that you will gain the best results from The Fuel Energizer is by following the easy "Golden Seven Steps Rule".

Comes in Tamper Proof Packing.Special Benefits of The Fuel Energizer:

Upto 28% Fuel saving on your mileage per litre
Increased acceleration
Reduction in AC drag
Upto 40% Reduction in Carbon Monoxide emissions
Reduction in exhaust smoke
Extends your engine life, cleans out carbon deposits
Upto 30% increase in life of your catalytic convertor exhaust system
A smoother running engine

How does The Fuel Energizer Work?

Most fuels for internal combustion engines are liquid, but liquid fuels do not combust until they are vaporized and mixed with air. Most emissions from motor vehicles consist of unburned hydrocarbon, carbon monoxide, and oxides of nitrogen. Unburned hydrocarbon and oxides of nitrogen react in the atmosphere and create smog. Smog is the prime cause of eye and throat irritation, noxious smells, plant damage and decreased visibility. Oxides of nitrogen are also toxic.

Generally, fuel for an internal combustion engine is composed of a set of molecules. Each molecule consists of a number of atoms made up from a nucleus and electrons which orbit around their nucleus. Magnetic movements already exist in these molecules and they therefore already have positive and negative electrical charges. However, because these molecules have not been realigned, the fuel is not actively interlocked with oxygen during combustion, the fuel molecules or hydrocarbon chains must be ionized and realigned. This ionization and realignment is achieved through the application of the magnetic field created by the Fuel Energizer.

Fuel mainly consists of hydrocarbons and when fuel flows through a magnetic field, such as the one created by the Fuel Energizer, the hydrocarbons change their orientation and molecules of hydrocarbon change their configuration. This has the effect of ensuring that the fuel actively interlocks with the oxygen, producing a more complete burn in the combustion chamber. The result is higher engine output, better fuel economy and a reduction in the hydrocarbons, carbon monoxide and oxides of nitrogen that are emitted through the exhaust. The ionization of the fuel also helps to dissolve the carbon build-up in carburetor jets, fuel injectors and combustion chambers, thereby keeping the engine in a cleaner condition.

The Fuel Energizer can be used in:

Scooters
Ambulances

If you want , you can use some solar plates in vehicle itself to charge its batteries.

Why Tricycles?

There are many advantages in using tricycle :

1) It is lighter than any vehicle around
2) It can be used to carry more than one person
3) There are pedals so dependence on electricity is not as much as motor bike.
4) Enough space to place large battery.

Solar Powered Air Conditoner


Air conditioners are both cause and solution of global warming, due to rise in temperature in recent years, it becomes necessary for each one of us to have air conditioner. It has become very important part of our life in recent years. The only problem is that it consumes great amount of electricity which results is more global warming.

One of the best solution of above problem is air conditioner which do not use electricity generated by pollution generating fuel, instead use something renewable and unconventional. One of the example for that is Solar Powered Air conditioner which takes its power from solar.Solar air conditioning refers to any air conditioning (cooling) system that uses solar power.

This project is part of solar project ideas and can be used by students of Mechanical or Electronics engineering. Even students of Physics would find it interesting.If this project is implemented with Passive Solar Design , it would be more effective.
