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.
What Is Animatronics
Animatronics
is a combination of animation and electronics. What exactly is an animatronic?
Basically, an animatronic is a mechanized puppet. It may be preprogrammed or
remotely controlled. The animatronic may only perform a limited range of
movements or it may be incredibly versatile. The scare created by the Great White coming out of the water in
"Jaws" and the tender otherworldliness of "E.T." are
cinematic effects that will not be easily forgotten. Later animatronics was
used together with digital effects. Through the precision, ingenuity and
dedication of their creators, animatronics creatures often seem as real to us
as their flesh-and-blood counterparts.
Introduction
The
first use of Audio-Animatronics was for Walt Disney's Enchanted Tiki Room in Disneyland,
which opened in June, 1963. The Tiki birds were operated using digital
controls; that is, something that is either on or off. Tones were recorded onto
tape, which on playback would cause a metal reed to vibrate. The vibrating reed
would close a circuit and thus operate a relay. The relay sent a pulse of
energy (electricity) to the figure's mechanism which would cause a pneumatic
valve to operate, which resulted in the action, like the opening of a bird's
beak. Each action (e.g., opening of the mouth) had a neutral position,
otherwise known as the "natural resting position" (e.g., in the case
of the Tiki bird it would be for the mouth to be closed). When there was no
pulse of energy forthcoming, the action would be in, or return to, the natural
resting position.
Jurassic Park
Long
before digital effects appeared, animatronics were making cinematic history.
But it was in Jurassic park that the best possible combination of animatronics
and digital effects were used together. Spinosaurus was a new dinosaur animatronic created for
"Jurassic Park III" by Stan Winston Studio (SWS). SWS worked with
Universal Studios and the film's production team to develop the Spinosaurus
design. Below lies the discussion of the amazing process that creates and controls
a huge animatronic like this dinosaur!

Electronic
Another group develops the electronic control
systems needed to operate the animatronic. Typically starting from scratch and
creating their own custom circuit boards, these engineers are essentially
building giant remote-controlled toys. Almost all of the movement of the
Spinosaurus will be manipulated by specialized remote-control systems known as
telemetry devices.
Structural
All of the electronic and mechanical
components need something to attach to and control, and the skin must have a
frame to maintain its shape. This is done by building a plastic and steel
frame. To increase the realism, and because it is the natural way to design it,
the frame of the Spinosaurus, as well as most other creatures made by SWS,
resembles the actual skeleton of the beast. This skeletal frame is largely
comprised of graphite, a synthetic material known for its strength and
lightness.
Surface
The "skin" of the Spinosaurus
is made from foam rubber, which is a very light, spongy rubber that is made by
mixing air with liquid latex rubber and then curing (hardening) it. While there
are other compounds, such as silicone and urethane, that are stronger and last
longer, foam rubber is used because it is much easier to work with. The
solution is poured into each mold and allowed to cure. As mentioned earlier,
parts of the frame are embedded with the foam rubber at certain points. To
further strengthen the skin, a piece of fabric is cut to size and embedded in
the foam rubber after it is poured into the mold. Once cured, each piece of
skin is pulled from its mold.
What Is An Animatronics Kit?
Everything you need (except batteries
and imagination) is included in our easy-to-use kit. Connect the cable to your
PC's serial port, install the software and you're ready to start. No soldering
or programming skills required. If you can use Windows you can use this
Animatronics Kit . The software allows you to record the movements of hobby
servos (up to two billion moves) and play them back exactly as recorded. Make
your creation come to life!
Conclusion
Creating a good animatronics figure that
is able to perform constantly without fail requires many special skills and
lots of technical know how. Before
assuming the task of creating an animatronic figure, you should have a strong hold on how these things
are constructed and be willing to spend a pretty penny on equipment and
materials.
