ANIMATRONICS

ABSTRACT

Animatronics is a cross between animation and electronics. Basically, an animatronic is a mechanized puppet. It may be preprogrammed or remotely controlled. An abbreviated term originally coined by Walt Disney as "Audio-Animatronics" (used to describe his mechanized characters), can actually be seen in various forms as far back as Leonardo-Da-Vinci's Automata Lion, (theoretically built to present lillies to the King of France during one of his Visits),and has now developed as a career which may require combined talent in Mechanical Engineering , Sculpting / Casting, Control Technologies, Electrical / Electronic, Airbrushing, Radio-Control.
Long before digital effects appeared, animatronics were making cinematic history. The scare generated by the Great White coming out of the water in "Jaws" and the tender otherworldliness of "E.T." were its outcomes. The Jurassic Park series combined digital effects with animatronics.

It is possible for us to build our own animatronics by making use of ready-made animatronic kits provided by companies such as Mister Computers where no programming skills are required.Only a knowledge of Windows is required.

Air powered cars

ABSTRACT

Have you been to the gas station this week? Considering that we live in a very mobile society, it's probably safe to assume that you have. While pumping gas, you've undoubtedly noticed how much the price of gas has soared in recent years. Gasoline which has been the main source of fuel for the history of cars, is becoming more and more expensive and impractical (especially from an environmental standpoint). These factors are leading car manufacturers to develop cars fueled by alternative energies. Two hybrid cars took to the road in 2000, and in three or four years fuel-cell-powered cars will roll onto the world's highways.

This seminar is to explain the working of air powered cars. These type of cars will run on compressed air instead of gasoline .The car is powered by a two cylinder compressed air engine.

The air powered car is also called as a low pollution or zero pollution cars. Since the car runs on compressed air it is environmentally friendly.
