Automaton in the context of "Jacquemart (bellstriker)"

A figurine (a diminutive form of the word figure) or statuette is a small, three-dimensional sculpture that represents a human, deity or animal, or, in practice, a pair or small group of them. Figurines have been made in many media, with clay, metal, wood, glass, and today plastic or resin the most significant. Ceramic figurines not made of porcelain are called terracottas in historical contexts.

Figures with movable parts, allowing limbs to be posed, are more likely to be called dolls, mannequins, or action figures; or robots or automata, if they can move on their own. Figurines and miniatures are sometimes used in board games, such as chess, and tabletop role playing games.

Reductionism is any of several related philosophical ideas regarding the associations between phenomena which can be described in terms of simpler or more fundamental phenomena. It is also described as an intellectual and philosophical position that interprets a complex system as the sum of its parts, contrary to holism. Reductionism tends to focus on the small, predictable details of a system and is often associated with various philosophies like emergence, materialism, and determinism.

The Canard Digérateur, or Digesting Duck, was an automaton in the form of a duck, created by Jacques de Vaucanson and unveiled on 30 May 1764 in France. The mechanical duck appeared to have the ability to eat kernels of grain, and to metabolize and defecate them. While the duck did not actually have the ability to do this—the food was collected in one inner container, and the pre-stored feces were "produced" from a second, so that no actual digestion took place—Vaucanson hoped that a truly digesting automaton could one day be designed.

Voltaire wrote in 1769 that "Without the voice of le Maure and Vaucanson's duck, you would have nothing to remind you of the glory of France."

Automata theory is the study of abstract machines and automata, as well as the computational problems that can be solved using them. It is a theory in theoretical computer science with close connections to cognitive science and mathematical logic. The word automata comes from the Greek word αὐτόματος, which means "self-acting, self-willed, self-moving". An automaton (automata in plural) is an abstract self-propelled computing device which follows a predetermined sequence of operations automatically. An automaton with a finite number of states is called a finite automaton (FA) or finite-state machine (FSM). The figure on the right illustrates a finite-state machine, which is a well-known type of automaton. This automaton consists of states (represented in the figure by circles) and transitions (represented by arrows). As the automaton sees a symbol of input, it makes a transition (or jump) to another state, according to its transition function, which takes the previous state and current input symbol as its arguments.

Automata theory is closely related to formal language theory. In this context, automata are used as finite representations of formal languages that may be infinite. Automata are often classified by the class of formal languages they can recognize, as in the Chomsky hierarchy, which describes a nesting relationship between major classes of automata. Automata play a major role in the theory of computation, compiler construction, artificial intelligence, parsing and formal verification.

An animatronic is a puppet controlled electronically to move in a fluent way. Animatronics are the modern adaptation of the automaton and are often used for the portrayal of characters in films, video games, and 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.

Hugo is a 2011 American adventure drama film directed and produced by Martin Scorsese, and adapted for the screen by John Logan. Based on Brian Selznick's 2007 book The Invention of Hugo Cabret, it tells the story of a boy who lives alone in the Gare Montparnasse railway station in Paris in the 1930s, only to become embroiled in a mystery surrounding his late father's automaton and the pioneering filmmaker Georges Méliès.

Hugo is Scorsese's first film shot in 3D, about which the filmmaker remarked, "I found 3D to be really interesting, because the actors were more upfront emotionally. Their slightest move, their slightest intention is picked up much more precisely." The film was released in the United States on November 23, 2011.

A brazen head, brass, or bronze head was a legendary automaton in the Middle Ages to the early modern period whose ownership was ascribed to late medieval scholars, such as Roger Bacon, who had developed a reputation as wizards. Made of brass or bronze, the male head was variously mechanical or magical. Like Odin's head of Mimir in Norse paganism, it was reputed to be able to correctly answer any question put to it, although it was sometimes restricted to "yes" or "no" answers. In the seventeenth century, Thomas Browne considered them to be misunderstanding of the scholars' alchemical work, while in modern times, Borlik argues that they came to serve as "a metonymy for the hubris of Renaissance intellectuals and artists". Idries Shah devotes a chapter of his book The Sufis to providing an interpretation of this "head of wisdom" as well as the phrase making a head, stating that at its source the head "is none other than the symbol of the [Sufic] completed man."
