Audio-Animatronics (also known as simply Animatronics, and sometimes shortened to AAs) is the registered trademark for a form of robotics animation created by Walt Disney Imagineering for shows and attractions at Disney theme parks, and subsequently expanded on and used by other companies. The robots move and often synchronise with audio by the assistance of an external sound system on the stage (generally a recorded speech or song).

The machines are usually fixed to whatever supports them.[1] They can sit and stand but cannot produce any form of locomotion. An Audio-Animatronic significantly deviates from an android-type robot in that it uses prerecorded movements and sounds, rather than responding to external stimuli. In 2009, Disney debuted an interactive version of the technology called Autonomatronics, and in 2018, announced aerial stunt figures called Stuntronics.

History

[

edit

]

Audio-Animatronics were originally a creation of Walt Disney employee Lee Adams, who worked as an electrician at the Burbank studio and was one of Disney's original Imagineers. Walt Disney got a mechanical toy bird in New Orleans, and he decided to improve the device that moved it. An early robotic figure was the Dancing Man, created by Roger Broggie and Wathel Rogers, and modeled after a tap dancing routine by actor Buddy Ebsen.[2] The system of the animatronics relies on a combination of electric motors, solenoids, hydraulic systems, pneumatic systems, and cables to produce repeatable puppet movements that syncs to sound.[3]

The term "Audio-Animatronics" was first used commercially by Disney in 1961, was filed as a trademark in 1964, and was registered in 1967.

Development of the first audio animatronic technology began in 1949 with the work of the giant squid for 20,000 leagues under the sea (1954). [3]

The Audio-Animatronic show The Enchanted Tiki Room opened in 1963 at Disneyland. It is a room full of tropical creatures with eye and facial actions synchronized to a musical score entirely by electromechanical means. The Audio-Animatronic cast of the musical revue uses tones recorded on tape to vibrate a metal reed that closes a circuit to trigger a relay, which sends a pulse of electricity to a mechanism that causes a pneumatic valve to move part of the figure.

The movements of the attraction's birds, flowers, and tiki idols are triggered by sound. Figures' movements have a neutral "natural resting position" that the limb or part returns to when there is no electric pulse present. Other than this, the animation is a digital system, with only on/off moves, such as an open or closed eye. The same kind of technology was used for the head of Mary Poppins robin cane in the 1964 movie. [3]

Can-can dancer doll, an audio-animatronic doll, represent France in the 1964 Disney boat ride It's a Small World.

Other early Audio-Animatronics were at the 1964 New York World's Fair. They were used in the Great Moments with Mr. Lincoln exhibit at the State of Illinois Pavilion, Pepsi/UNICEF's "it's a small world" exhibit, General Electric's Carousel of Progress, and Ford Motor Company's "Magic Skyway."

An Audio-Animatronic robin sang a duet with Julie Andrews in the 1964 film Mary Poppins.

Technology

Pneumatic actuators are powerful enough to move heavier objects like simulated limbs, while hydraulics are used more for large figures. On/off type movement would cause an arm to be lifted (for example) either up over an animatronic’s head or down next to its body, but with no halting or change of speed in between. To create more realistic movement in large figures, an analog system was used. This gave the figures' body parts a fully fluid range of motion, rather than only two positions.

To permit a high degree of freedom, the control cylinders resemble typical miniature pneumatic or hydraulic cylinders, but mount the back of the cylinder on a ball joint and threaded rod. This ball joint permits the cylinders to float freely inside the frame, such as when the wrist joint rotates and flexes.

The oil-filled cylinders occasionally drip or leak, so it is sometimes necessary to do makeup touch-up work, or to strip the clothing off a figure due to leaking fluids inside. The Enchanted Tiki Room remains a pneumatic theatrical set, primarily due to the leakage concerns, as the Audio-Animatronic figures are above the audience's heads.

Because each individual cylinder requires its own control channel, the original Audio-Animatronic figures were relatively simple in design, to reduce the number of channels required. For example, the first human designs (referred to internally by Disney as series A-1) included all four fingers of the hand as one actuator. It could wave its hand but it could not grasp or point at something. With modern digital computers controlling the device, the number of channels is virtually unlimited, allowing more complex, realistic motion. The current versions (series A-100) now have individual actuators for each finger. Disney also introduced a brand new figure that is used in Star Wars: Galaxy's Edge and is referred to as the A1000.

Compliance

[

edit

]

Compliance is a new technology that allows faster, more realistic movements without sacrificing control. In the older figures, a fast limb movement would cause the entire figure to shake in an unnatural way. The Imagineers thus had to program slower movements, sacrificing speed in order to gain control. This was frustrating for the animators, who, in many cases, wanted faster movements. Compliance improves this situation by allowing limbs to continue past the points where they are programmed to stop; they then return quickly to the "intended" position, much as real organic body parts do. The various elements also slow to a stop at their various positions, instead of using the immediate stops that caused the unwanted shaking. This absorbs shock, much like the shock absorbers on a car or the natural shock absorption in a living body.

Cosmetics

[

edit

]

The skin of an Audio-Animatronic is made from silicone rubber. Because the neck is so much narrower than the rest of the skull, the skull skin cover has a zipper up the back to permit easy removal. The facial appearance is painted onto the rubber, and standard cosmetic makeup is also used. Over time, the flexing causes the paint to loosen and fall off, so occasional makeup work and repainting are required.

Generally as the rubber skin flexes, the stress causes it to dry and begin to crack. Figures that do not have a high degree of motion flexibility, such as the older A-1 series for President Lincoln, may only need to have their skin replaced every ten years. The most recent A-100 series human AAs, like the figure for President Barack Obama, also include flexion actuators that move the cheeks and eyebrows to permit more realistic expressions; however, the skin wears out more quickly and needs replacement at least every five years.

The wig on each human is made from natural human hair for the highest degree of realism, although using real hair creates its own problems, since the changing humidity and constant rapid motions of the moving AA carriage hardware throughout the day cause the hair to slowly lose its styling, requiring touch-ups before each day's showing.

Autonomatronics

[

edit

]

Autonomatronics is a registered trademark for a more advanced Audio-Animatronic technology, also created by Walt Disney Imagineers.

The original Audio-Animatrons used hydraulics to operate robotic figures to present a pre-programmed show. This more sophisticated technology can include cameras and other sensors feeding signals to a high-speed computer which processes the information and makes choices about what to say and do. In September 2009, Disney debuted "Otto", the first interactive figure that can hear, see and sense actions in the room.[4] Otto can hold conversations and react to the audience.[5]

In December 2009, Great Moments with Mr. Lincoln returned to Disneyland using the new Autonomatronics technology.[6]

Stuntronics

[

In June 2018, it was revealed that Disney Imagineering had created autonomous, self-correcting aerial stunt robots called stuntronics.[7] This new extension of animatronics utilizes onboard sensors for precision control of advanced robotics to create animatronic human stunt doubles that can perform advanced aerial movements, such as flips and twists.[8]

Jack Sparrow AA in Pirates of the Caribbean at Disneyland

The technology of the AAs at Disney's theme parks around the world vary in their sophistication. They range from the blinking and mouth movements at Walt Disney's Enchanted Tiki Room to full body movement, from the mouth to the tip of the fingers at the former Stitch's Great Escape! attraction at the Magic Kingdom.

Current technologies have paved the way for more elaborate AA figures, such as "Ursula head" inside the Mermaid Lagoon Theater at Tokyo DisneySea, the Indiana Jones figures inside the Indiana Jones attractions at both Disneyland and Tokyo DisneySea, the "swordfighting" pirates inside Pirates of the Caribbean at Disneyland Park (Paris), the "lava/rock monster" inside Journey to the Center of the Earth at Tokyo DisneySea, the "Na'vi Shaman of Songs" inside the Na'vi River Journey, the dinosaurs inside DINOSAUR, the "Yeti" inside Expedition Everest at Disney's Animal Kingdom (though the latter has been non-functional since 2008, using a strobe light to simulate movement of the still figure[9][10]), or the Roz figure inside Monsters, Inc. Mike & Sulley to the Rescue! at Disney California Adventure.

The Roz figure is able to "interact" with guests with help from an unseen ride operator who chooses pre-recorded messages for Roz to "speak", thereby seeming to "react" to individual guests' unique appearances and clothing. Mr. Potato Head outside of the Toy Story Mania! attractions at the Disney California Adventure and Disney's Hollywood Studios parks does the same.

One of the newest figures comes with changes to the classic Pirates of the Caribbean attraction at Disneyland and the Magic Kingdom, both now featuring characters from the Pirates of the Caribbean film series. The Jack Sparrow figure is based on the actor that portrays him, Johnny Depp, and features his voice and facial mold. So far, the newest and most advanced Audio-Animatronic figure is Abraham Lincoln at The Disneyland Story: Featuring Great Moments With Mr. Lincoln at Disneyland. Lincoln can move his lips to form words, can make dramatic movements, and can portray emotions to match the words he is saying.

The Audio-Animatronic anglerfish inside The Seas with Nemo & Friends in Epcot uses a robotic arm that is connected to a puppet to control realistic swimming movements of the animatronic to make the effect that the anglerfish is actually swimming. Robotic arms have also appeared in other attractions such as The Sum of All Thrills in the Innoventions area of Epcot.

The Audio-Animatronic Indiana Jones figures inside Indiana Jones Adventure: Temple of the Crystal Skull at Tokyo DisneySea resemble actor Harrison Ford, unlike the original figures found at the Disneyland version, Temple of the Forbidden Eye. In 2010, some of the Audio-Animatronic figures at the Disneyland version were replaced with more technically advanced figures that also look more like Ford.

The Audio-Animatronics formerly featured in the Great Movie Ride used the likeness of the actors that portrayed the characters. Audio-Animatronics found in Seven Dwarfs Mine Train at Magic Kingdom use projections for their faces to make the dwarfs' mouths move and their eyes blink. The projected face technology is also used in Frozen Ever After at Epcot. These Audio-Animatronics were succeeded by the figures in use in the Star Wars: Galaxy's Edge lands at Disneyland and Disney's Hollywood Studios in 2019, such as Hondo Ohnaka in the Millennium Falcon – Smugglers Run attraction. These new figures, known as A-1000 Animatronics, have a fully functional face, featuring a full range of motion in the eyes and mouth.[11]

Society

[

edit

]

Society has a large affect on how animatronics evolve over time in theme parks. At parks like Disney animatronics are constantly being pulled out and put in based on popular movies and the changing of generations. Some rides like The Hall of Presidents are affected greatly when it comes to events in society because every time there is a new president they are added to the hall. Disney is prepared because they make both presidents to add the right one in after the elections. This is one of the reasons why things can get controversial because they have to add the president who wins. [12]

What Is Disney Audio-Animatronics Technology?

For decades, Disney has provided unforgettable theme park experiences for guests around the world. Awe-inspiring sights and attractions are regularly unveiled, with millions of guests pouring into Disney Parks to experience them firsthand. 

Since its beginning, Disney’s inventive spirit has given rise to new technologies that have grown popular far and wide. One of these innovations, Disney Audio-Animatronics technology, helped usher in a new era of theme park entertainment and played a role in molding The Walt Disney Company into what it is today. 

What are Audio-Animatronics figures?

Audio-Animatronics figures are moving — often speaking — lifelike figures that bring Disney’s beloved characters and experiences to life. Effortlessly complementing Disney’s storytelling tradition, these figures are designed and built by Disney Imagineers to embody the blend of imagination, innovation and spectacle that Disney is known for.  

Audio-Animatronics figures let guests interact with Disney characters, creating tangible, memorable moments as they enjoy captivating rides and attractions. 

History of Disney Audio-Animatronics technology

Walt Disney championed the arrival of Audio-Animatronics figures as he sought to give park guests a chance to see their favorite characters in person.

In the early days of Walt Disney’s original park, Disneyland, Walt encountered a small mechanical bird in an antique shop when he was visiting New Orleans. While perched inside an antique cage, the toy mimicked the movements and sounds of a real bird, spurring Walt’s imagination. 

After purchasing the antique bird, Walt returned to his park, where Wathal Rogers and other Imagineers deconstructed the bird to determine how it worked. After some careful research, Disney’s talented team figured out the secrets behind this technology and made plans to unveil Audio-Animatronics figures on a much larger scale. 

The first of these new-age creations to dazzle Disneyland guests inhabited the Enchanted Tiki Room. Opened in 1963, the attraction now features over 200 moving, speaking and singing birds and flowers, all built with an emphasis on detail and lifelike motion. The Enchanted Tiki Room’s opening and success paved the way for an expansion of Audio-Animatronics technology, with even more advanced iterations announced in later years. 

Long-deceased American presidents spoke and gestured from the stage. Dinosaurs roamed the earth anew, and pirates danced and swaggered in real time. Disney Audio-Animatronics figures became signature attractions in the early years of Disneyland. Today, these technological marvels can be found at every Disney theme park, creating magical moments for guests of all ages. 

How do Audio-Animatronics figures work?

Behind their lifelike appearance, Disney Audio-Animatronics figures house a network of intricate components working in harmony to produce movements that mimic human gestures and expressions. These components also enable the animatronics to react to guests in real time, creating spontaneous moments and a more immersive, realistic experience.

Many of Disney’s Audio-Animatronics figures are designed to move in concert, with choreographed movements timed by complex audio cues and digital signals. These movements require extensive engineering — courtesy of Disney Imagineers — and programming to create a seamless display of characters in action. 

Disney attractions that use Audio-Animatronics technology

Disney Audio-Animatronics figures are a foundational element of the special experience the parks consistently deliver. 

As this technology continues to evolve, Disney finds new and creative ways of incorporating Audio-Animatronics figures into attractions. Here’s a look at several popular attractions that showcase some of the best that Audio-Animatronics technology has to offer. 

  • World of Frozen: The world’s first Frozen-themed land recently debuted at Hong Kong Disneyland Resort, redefining immersive storytelling and taking the guest experience to the next level with some of the most technologically advanced Audio-Animatronics figures ever created. World of Frozen features beloved Frozen characters coming to life, including Olaf and Sven, who welcome guests by singing “Do You Want To Build a Snowman?” 
  • Star Wars: Rise of the Resistance: A more modern use of Audio-Animatronics characters, Star Wars: Rise of the Resistance has set a new standard for immersion and realism. On this attraction, found at both Disneyland and Disney’s Hollywood Studios, guests face an exciting escape from the clutches of the First Order with the help of Rey and BB-8. Along the way, riders will find action-packed encounters with Star Wars characters like stormtroopers, droids and even Kylo Ren. 
  • Pirates of the Caribbean: Pirates of the Caribbean, an attraction where Audio-Animatronics figures take center stage, debuted in 1967. Located at both Disneyland and Walt Disney World, guests travel down a winding waterway, encountering singing, dancing pirates who share tales from their lives at sea with a lighthearted song. With careful attention to detail and fluid, lifelike movements, the Audio-Animatronics figures in Pirates of the Caribbean continue to enchant guests decades after the attraction was revealed. 
  • “it’s a small world”: One of Disney’s first attractions to feature Audio-Animatronics technology is also one of its most extensive. “it’s a small world” features nearly 300 animatronics, each with its own specific movements and speech capabilities. The world-renowned attraction offers a journey through the international world, where Audio-Animatronics figures representing world cultures greet guests along the way. Given its staggering popularity and status as a Disney classic, this attraction has been adapted in Disney parks across the globe. In addition to its original home in Disneyland, “it’s a small world” delights guests at Magic Kingdom, Tokyo Disneyland, Disneyland Paris and Hong Kong Disneyland.
