# Animatronics

An animatronic is a mechatronic puppet controlled electronically by machine to move in a fluent way. They are a modern variant of the automaton and are often used for the portrayal of characters in films, video games and in theme park attractions.
Animatronics are a multidisciplinary field integrating puppetry, anatomy and mechatronics. Animatronic figures can be implemented with both computer and human control, including teleoperation. Motion actuators are often used to imitate muscle movements and create realistic motions. Figures are usually encased in body shells and flexible skins made of hard or soft plastic materials and finished with colors, hair, feathers and other components to make them more lifelike. Animatronics stem from a long tradition of mechanical automata powered by hydraulics, pneumatics and clockwork.
Before the term "animatronics" became common, they were usually referred to as "robots". Since then, robots have become known as more practical programmable machines that do not necessarily resemble living creatures. Robots (or other artificial beings) designed to convincingly resemble humans are known as "androids". The term animatronics is a portmanteau of animate and electronics. The term Audio-Animatronics was coined by Walt Disney in 1961 when he started developing professional animatronics for entertainment and film.

## History

Before electronics, animatronics were simply puppets made to work with clockwork. These are known today as atomata. For most of human history, it has not been possible to create a moving figure resembling a person that was not directly puppeted by another person.
In the renaissance era, the first clockwork automated humanoid figures were created. These were complex with many movements, however the figures were extremely large as they contained large cam shaft mechanisms in the base with the introduction of electricity. The mechanisms to create a humanoid figure got smaller and smaller, however very few of the created figures looked human.
The first audio animatronic to convincingly imitate a human was Walt Disney's Abraham Lincoln attraction at the Illinois State Pavilion of the 1964 New York World's Fair. This marked a change in the industry, as computers were a pivotal part in creating the figure.
* 1939 (1939) – 1939 (1939): Sparko, The Robot Dog, and Elektro, performs in front of the public. Both were manufactured by the Westinghouse Electric Corporation. Elektro was one of the first robots, using basic sensors and tube logic to receive commands and roughly know when it crashed into a wall. It could blow up balloons, smoke cigarettes, synthesize text, and move its legs and arms. In 1939, Elektro received a pet, and the first mainstream animatronic, Sparko. However, unlike Elektro, Sparko had no built-in computer and was not remote controlled, instead using an external computer controlled by an operator. Unlike many depictions of robots in that time, Sparko represented a living animal, and thus became the very first modern day animatronic character, along with an unnamed horse which was reported to gallop realistically. The animatronic galloping horse was also on display at the 1939 New York World's Fair, in a different exhibit than Sparko's.

## Design

There are quite a few ways to build an animatronic, however most follow this basic structure:
An animatronics character is typically designed to be as realistic as possible and thus, is built similarly to how it would be in real life. The framework of the figure is like the "skeleton". Joints, motors, and actuators act as the "muscles". Connecting all the electrical components together are wires, such as the "nervous system" of a real animal or person. Steel, aluminum, plastic, and wood are all commonly used in building animatronics but each has its best purpose. The relative strength, as well as the weight of the material itself, should be considered when determining the most appropriate material to use. The cost of the material may also be a concern. Several materials are commonly used in the fabrication of an animatronics figure's exterior. Dependent on the particular circumstances, the best material will be used to produce the most lifelike form. For example, "eyes" and "teeth" are commonly made completely out of acrylic.
Some examples of different methods of building animatronics are Chuck E. Cheese's studio c animatronic, made of latex rubber, metal, and plastic supported by an internal skeleton and on the other end of the spectrum is the all metal bunyip animatronic in Australia, using water to actuate the characters mouth.

### Materials

* Latex: White latex is commonly used as a general material because it has a high level of elasticity. It is also pre-vulcanized, making it easy and fast to apply. Latex is produced in several grades. Grade 74 is a popular form of latex that dries rapidly and can be applied very thick, making it ideal for developing molds. Foam latex is a lightweight, soft form of latex which is used in masks and facial prosthetics to change a person's outward appearance, and in animatronics to create a realistic "skin". The Wizard of Oz was one of the first films to make extensive use of foam latex prosthetics in the 1930s.
* Silicone: Disney has a research team devoted to improving and developing better methods of creating more lifelike animatronics exteriors with silicone. RTV silicone (room temperature vulcanization silicone) is used primarily as a molding material as it is very easy to use but is relatively expensive. Few other materials stick to it, making molds easy to separate. Bubbles are removed from silicone by pouring the liquid material in a thin stream or processing in a vacuum chamber prior to use. Fumed silica is used as a bulking agent for thicker coatings of the material.
* Polyurethane: Polyurethane rubber is a more cost effective material to use in place of silicone. Polyurethane comes in various levels of hardness which are measured on the Shore scale. Rigid polyurethane foam is used in prototyping because it can be milled and shaped in high density. Flexible polyurethane foam is often used in the actual building of the final animatronic figure because it is flexible and bonds well with latex.
* Plaster: As a commonplace construction and home decorating material, plaster is widely available. Its rigidity limits its use in molds, and plaster molds are unsuitable when undercuts are present. This may make plaster far more difficult to use than softer materials like latex or silicone.

### Movement

Pneumatic actuators can be used for small animatronics but are not powerful enough for large designs and must be supplemented with hydraulics. To create more realistic movement in large figures, an analog system is generally used to give the figures a full range of fluid motion rather than simple two position movements.
Mimicking the often-subtle displays of humans and other living creatures, and the associated movement is a challenging task when developing animatronics. One of the most common emotional models is the Facial Action Coding System (FACS) developed by Ekman and Friesen. FACS defines that through facial expression, humans can recognize six basic emotions: anger, disgust, fear, joy, sadness, and surprise. Another theory is that of Ortony, Clore, and Collins, or the OCC model which defines 22 different emotional categories.
In 2020 Disney revealed its new animatronics robot that can breathe, move its eyes very much like humans, and identify people around it in order to select "an appropriate" response, as opposed to previous Disney animatronics that were used in purely scripted, non-interactive situations, like theme park rides.

## Training and education

Animatronics has been developed as a career which combines the disciplines of mechanical engineering, casting/sculpting, control technologies, electrical/electronic systems, radio control and airbrushing.
Some colleges and universities do offer degree programs in animatronics. Individuals interested in animatronics typically earn a degree in robotics which closely relate to the specializations needed in animatronics engineering.
Students achieving a bachelor's degree in robotics commonly complete courses in:
* Mechanical engineering
* Industrial robotics
* Mechatronics systems
* Modeling of robotics systems
* Robotics engineering
* Foundational theory of robotics
* Introduction to robotics

## In popular culture

Animatronic characters appear in both films and video games, most notably in horror genre and survival horror video games that generally features possessed animatronics as antagonists.

### In films

The film industry has been a driving force revolutionizing the technology used to develop animatronics. Animatronics are used in situations where a creature does not exist, the action is too risky or costly to use real actors or animals, or the action could never be obtained with a living person or animal. Its main advantage over CGI and stop motion is that the simulated creature has a physical presence moving in front of the camera in real time. The technology behind animatronics has become more advanced and sophisticated over the years, making the puppets even more lifelike.
Animatronics were first introduced by Disney in the 1964 film Mary Poppins which featured an animatronic bird. Since then, animatronics have been used extensively in such movies as Jaws and E.T. the Extra-Terrestrial.
Directors such as Steven Spielberg and Jim Henson have been pioneers in using animatronics in the film industry; a film co-directed by the latter, The Dark Crystal, showcased groundbreaking puppets designed by Brian Froud and created by Henson's then recently established Creature Shop in London.
The 1993 film Jurassic Park, directed by Spielberg, used a combination of computer-generated imagery in conjunction with life-sized animatronic dinosaurs built by Stan Winston and his team. Winston's animatronic "T. rex" stood almost 20 feet (6.1 m), 40 feet (12 m) in length and even the largest animatronics weighing 9,000 pounds (4,100 kg) were able to perfectly recreate the appearance and natural movement on screen of a full-sized Tyrannosaurus rex.
Jack Horner called it "the closest I've ever been to a live dinosaur". Critics referred to Spielberg's dinosaurs as breathtakingly and terrifyingly realistic.
The 1999 BBC miniseries Walking with Dinosaurs was produced using a combination of about 80% CGI and 20% animatronic models. The quality of computer imagery of the day was good, but animatronics were still better at distance shots, as well as closeups of the dinosaurs. Animatronics for the series were designed by British animatronics firm Crawley Creatures. The show was followed up in 2007 with a live adaptation of the series, Walking with Dinosaurs: The Arena Spectacular.
Geoff Peterson is an animatronic human skeleton that serves as the sidekick on the late-night talk show The Late Late Show with Craig Ferguson. Often referred to as a "robot skeleton", Peterson is a radio-controlled animatronic robot puppet designed and built by Grant Imahara of MythBusters.

### Films focusing on animatronics

* The Banana Splits Movie, a 2019 American comedy horror film starring Dani Kind, Steve Lund, Sara Canning, and the voice of Eric Bauza, follows a young boy and his family who, as a birthday present, attend a live taping of a successful children's television series featuring Fleegle, Bingo, Drooper, and Snorky, four goofy-like animatronic characters. However, their new software updates go haywire upon learning the upcoming cancellation of their show and the characters start a killing spree that the crew and audience must survive. It is a horror reimagining of the 1968-1970 Hanna-Barbera's television series of the same name.
* Willy's Wonderland, a 2021 American action comedy horror film starring Nicolas Cage, Emily Tosta, David Sheftell and Beth Grant, follows a quiet drifter who is tricked into cleaning up a once-successful abandoned family entertainment center while battling the restaurant's eight murderous animatronic characters (possessed by souls of cannibalistic serial killers) with the aid of a teenager and her friends.
* Five Nights at Freddy’s, a 2023 American supernatural horror film starring Josh Hutcherson, Elizabeth Lail, Piper Rubio, Mary Stuart Masterson, and Matthew Lillard, follows a troubled young man caring for his 10-year-old sister who is suggested by his career counselor to take up a night shift job at a once-successful abandoned family entertainment center, while keeping an eye on the restaurant's four murderous animatronic characters Freddy Fazbear, Bonnie, Chica, and Foxy (possessed by the spirits of five missing dead children) while trying to figure out unsolved disappearance of his younger brother more than a decade before. It is based on the Five Nights at Freddy's video game series created by Scott Cawthon.

### Short films

* The Hug, a 2018 horror short film directed by Jack Bishop and Justin Nijm, and starring Nick Armstrong and Roman George, follows a bratty birthday boy at Pandory's Pan Pizza Palace, a ShowBiz Pizza Place-like restaurant, who has an awkward situation with Pandory the Panda, the pizzeria's giant panda animatronic mascot. It premiered at Hulu as part of its "Huluween" film competition.

### Television

* The Capicola Gang, a trio of evil anthropomorphic animatronic animals from The Fun Fun Zone, consisting of Dominic (a robot bear, although listed in the credits as Main Bear), who is based on Vito Corleone from The Godfather, Louie (a robot beaver), and Amelia (a robot duck, although listed in the credits as Duck Lady), are the main antagonists in the Regular Show episodes "Fuzzy Dice" and "Steak Me Amadeus". The Capicola Gang Leader had a cameo appearance as an incriminating witness in "Can you Ear Me Now?" where he testified in court against Mordecai and Rigby. They share a resemblance to the characters from the popular game series Five Nights at Freddy's and the popular kids entertainment center Chuck E. Cheese.
* Hoo-Ha's Jamboree, an animatronic band at Hoo-Ha Owl's Pizzamatronic Jamboree, and a parody of The Rock-afire Explosion of ShowBiz Pizza Place, which consist of Hoo-Ha the Owl (guitarist, and lead singer), Cheerleader (banjoist), Beaver (guitarist), Rat in a Barrel (two same animatronics sit on either side of the stage), Cowboy Frog (bongo player), and Will E. Badger (opening act) are the secondary antagonists in the Gravity Falls episodes "Soos and the Real Girl", "Weirdmageddon Part 1", and "Weirdmageddon 2: Escape From Reality".

### Advertising

The British advertisement campaign for Cadbury Schweppes titled Gorilla featured an actor inside a gorilla suit with an animatronically animated face.
The Slowskys was an advertising campaign for Comcast Cable's Xfinity broadband Internet service. The ad features two animatronic turtles, and it won the gold Effie Award in 2007.

### Video games

* Five Nights at Freddy's (commonly known as FNaF), a horror video game series, features various animatronic entertainers as antagonists who try to kill the player character, who is typically a nighttime security guard or employee at one of the facilities (usually a pizzeria) where the animatronics reside. In the first game of the series Five Nights at Freddy's, the animatronics' violent attitude towards humans at night is explained away as faulty programming, which causes them to mistake the protagonist for an endoskeleton without a character suit on—which goes against the establishment's rules. As a result, the animatronics try to "forcefully stuff" the player character into a suit, resulting in their death. However, the games feature a deep lore (gradually revealed through various minigames and Easter eggs) which reveals that many of the animatronics are actually haunted by the spirits of children whose deaths are somehow connected to the fictional restaurant franchise "Freddy Fazbear's Pizza". At least six of these children were murdered by William Afton (a.k.a. "The Purple Guy"), one of the co-founders of the original restaurant and the series' overarching villain, who would go on to possess an animatronic of his own after his death. Since the original game, Five Nights at Freddy's has evolved into a large media franchise comprising various sequels, prequels and spin-offs, fan games, a novel trilogy, and an anthology series of short stories. A film adaptation Five Nights at Freddy's was released on October 27, 2023.

### Toys

Some examples of animatronic toys include TJ Bearytails, Big Mouth Billy Bass, FurReal, Kota the triceratops, Pleo, WowWee Alive Chimpanzee, Microsoft Actimates, and Furby. Well-known brands include Cuddle Barn, PBC International, Telco, Sound N Light, Nika International, Gemmy Industries, Tickle Me Elmo, Chantilly Lane and Dan Dee.
