Animation throughout the ages



History is rich with descriptions of attempts to imitate life by mechanical means in the form of hydraulic, pneumatic, or clockwork operated biological automata. Automata (or automatons - a machine which is relatively self-operating and capable of performing multiple complex movements on its own without the need for human control) had its greatest period of development following the rise of mechanicism with the revival of Greek culture during the Renaissance. There were, for example, isolated descriptions of talking heads claimed to have been constructed by Albertus Magnus, Roger Bacon, Gerbert, and Robert Grosseteste. Perhaps of greater significance was the mechanical lion of da Vinci and the two automata created by Johannes Muller, called Regiomontanus (1436-1476). One of these was the fabled eagle which was claimed to have escorted the Emperor Maximilian to the city gates of Nuremberg.
The first android, a completely mechanical figure which simulated a living human or animal, operating with apparently responsive action, is believed to have been constructed by Hans Bullmann of Nuremberg (?-1535). Bullmann reportedly produced a number of extremely ingenious figures of men and women that moved and played musical instruments.

These early automata were mechanical devices that seemed to demonstrate lifelike behaviour. They took advantage not only of gears, but also of gravity, hydraulics, pulleys and sunlight - the effect could be dazzling, as with the extraordinary clock of Berne created in 1530. This massive timepiece hourly disgorged a dazzling pageantry of automata figures.
One of the most famous waterworks of the seventeenth century was that constructed at the chateau at Heilbrunn in about 1646. It featured various animated hydromechanical devices. A mechanical theatre was installed here in 1725 by Lorenz Rosenegge, a craftsman of Nuremberg. It featured 256 figures, 119 of which were animated by means of a single water turbine. A horizontal axis operating a series of cams regulated the movements of the figures by means of copper wires. The wheelwork consists of wooden wheels with iron teeth and pinions. A powerful hydraulic organ provides background music and covers the noise of the mechanism.

Just as the waterworks and grottoes of the Renaissance gardens were tangible revivals of the hydraulic and pneumatic devices of the ancient Greek culture, some of the same influence filtered into the field of clockmaking. The first conversion from the hydraulic and pneumatic to the purely mechanical automata, occurred in Europe with the advent of the clockmaker who made public and astronomical clocks with moving figurines.

It was a short step to a combination of the pinned cylinder and the spring-driven clockwork to provide the sound of living things and of musical instruments in automata. This combination made possible a great variety of developments in the late seventeenth and during the eighteenth centuries. The most notable of these were the androids constructed in the mid-eighteenth century by Jacques Vaucanson (1709-1782), who brought the production of automata to its highest point of development. Vaucanson is unquestionably the most import inventor in the history of automata, as well as one of the most important figures in the history of machine technology. Although he was responsible for pioneering in the development of machine tools and later inspired the work of Sir Henry Maudslay and others, it was, ironically enough, his automata -- which occupied the briefest interlude in his life -- which brought him permanent fame and fortune.

Born in 1709 in Grenoble, France, Vaucanson exhibited great mechanical ability at a very early age. After having attended the oratory college at Juilly he studied with the Jesuits at Grenoble, and in 1725 joined the order of Minims of Lyon. During his training period, however, Vaucanson indulged his mechanical interests by creating automatically flying angels. This impelled the provincial of the order to destroy his makeshift workshop, and Vaucanson used the incident as an excuse to to be relieved of his clerical vows.

Vaucanson moved to Paris and, in direct contrast with his recent religious life, gave himself up to a life of debauchery while he undertook the studies of mechanics, music, and anatomy. He developed an interest in the study of medicine and attempted to construct a "moving anatomy" which reproduced the principal organic functions. Debts, illness, and eventually boredom caused him to abandon the project. He went on to the construct his famous androids, which made him wealthy and famous throughout Europe.

In 1735 Vaucanson began to formulate plans for the construction of the first android, which was to be a life-sized figure of a musician, dressed in a rustic fashion and playing eleven melodies on its flute, moving the levers realistically by its fingers and blowing into the instrument with its mouth. In October 1737 the automaton was completed and exhibited first at the fair of Saint-Germain and later at Longueville. All Paris flocked to see the mechanical masterpiece with the human spirit; the press was extremely favorable, and Vaucanson was launched upon his career.

Vaucanson's third and most famous automaton was "an artificial duck of gilt brass which drinks, eats, flounders in water, digests and excretes like a live duck" (see figure top right). It was Vaucanson's intention to create in this duck the "moving anatomy" that he had visualized once before. Accordingly, the figure of the duck was produced full size of gilt brass in a simplified form, the body pierced with openings to permit the public to observe the process of digestion. The complexity of this duck was enormous - there were over four hundred moving pieces in a single wing.

Just as spring-wound clockwork made possible mechanical music for automata, it also made possible the reproduction of the sound of words by mechanical means. In the seventeenth century Kircher had affirmed that it was possible to produce a head which moved the eyes, lips, and tongue, and, by means of the sounds which it emitted, appeared to be alive. A similar project was attempted in 1705 by Valentin Merbitz, rector of the Kreuzschule of Dresden, who devoted five years to it. The next major advance in this field was made in about 1770 by Friedrich von Knauss of Vienna, who constructed four speaking heads. That his project was not completely successful is attested to by the fact that in 1779 the Academy of Sciences in St. Petersburg used the production of a successful speaking head as the theme for a contest for mechanicians and organ manufacturers, specifying that the machine be capable of speaking the five vowels. - The Turing Test of its day for clocksmiths and mechanical engineers?

The most spectacular of all automata that have survived until the present day are The Writer, The Artist, and The Musician produced by Pierre Jacquet-Droz (1771-1790) and his son Henry-Louis (1753-1791) of Geneva. Father and son combined all the technical developments known in their time in an effort to produce a machine that faithfully imitated a human being, and their efforts were as successful as any have ever been. The Writer, a life-size and lifelike figure of a boy seated as a desk, is capable of writing any message of up to 40 letters in length (above right).

With a public fascination for the newly discovered force of electricity, fictional writing suggested that pieces of dead flesh sewn together could be 'animated' into life just as severed frog legs could be kicked into a reflex action by a crude battery in a science laboratory demonstration.

Having discarded the earlier technologies of hydraulics, pneumatics, clockwork, which where thought to hold the key, man continues his quest to create life through robotics and electronics, and with more abstract notions of life using computers to create artificial life (AI), autonomous systems, Celluar Automata and nanotechnology. Man now plays directly with the building blocks of life itself via genetic engineering
