ANIMATRONICS

•Animatronics is a mechanized puppet. It may be preprogrammed or remotely controlled.

•The animatronics may perform movements or it may be incredibly versatile.

This concept was developed for Disney studios, used in

1954 film version 20,000 leagues under the sea.

First use Audio-Animatronics was for walt Disney’s

Enchanted Tiki Room in Disneyland,which open in June

1963

Walt and WED knew that this pneumatic system could

not be sufficiently handle then Digital programming

was devised.

Wathel and Marc Davis developed « arm lift action »

WALT DISNEY'S ENCHANTED TIKI

ROOM,1963

first use of Audio-Animatronics.

using digital controls.

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.

At air pressure.

THEME PARKS AND

CINEMATOGRAPHY

Analog programming.

New "analog system" involved the use of voltage regulation.

All individual actions were then rerecorded onto a single reel--up to ten actions, each activated by a different tone, could be combined onto a single reel.

Electronics is used in doing programming of these animated creatures.

It is done by controlling the voltage regulation.

It is also done by embedded microcontroller.

Animatronics puppet that is animated by means of electromechanical devices.

Actuators are responsible for various facial movements.

Electronics and software provides synchronization of sound and motion.

Step 1: Designing

Step2:Sculpting

Step 3: Mold making

Step 4: Armature Fabrication

Step 5: Costuming

Step 6: Programming

Put it on paper.

Build a maquette (miniature model or primary model).

Build a full-size sculpture.

Create a mold (from the sculpture) and cast the body.

Build the animatronic components.

Put it all together.

Test it and work out any bugs.

PUT IT ON PAPER

DESIGNING

Client and the company developingthe animatronics decide what thecharacter will be, its appearancetotal number of moves, quality ofmoves, and what each specific movewill be. Budgets ,time lines etc.

SCULPTING

Converting two-dimensional ideas into three-dimensional forms.

This team can work from photos, artwork, videos, models, statuettes and similar likenesses.

MOLD MAKINGThis department creates the molds

that will ultimately produce the character skins.

Molds can be soft or hard, single or multiple pieces, and reusable or non-reusable. After the mold is finished and cured,

it is ready for skin making. Fiberglass shells are simultaneously being laid up to

form the body and limb shapes.

ARMATURE

FABRICATION

Each individual part requires a custom design and fabrication.

Each of the robot’s movement axis point must have an industrial rated bearing to provide action and long life.

The technicians select those components carefully in order to ensure the durability and long life.

BUILD A FULL-SIZE

COSTUMING

The outfit has to allow for easy acces to the character’s operating mechanisms. It must also “look” normal after movement has taken place.

The costume must be designed to provide hundreds or thousands of operations without wearing out and without causing the skin areas(i.e. around the necks or wrists) to breakdown as well

PROGRAMMING

Programming is the final step, and for some animations it is the most rewarding. Programming can be done either at the manufacturing facility or at the final installation site. In programming, all the individual moves are coordinated into complex animated actions and it bring “life.”
