СAUTOMATION AND ITS HISTORY
The first tools made of stone represented prehistoric man’s attempts toиdirect his own physical strength under the control of human intelligence. Thousands of years were required for the development of simple mechan-
ical devices and machines such as the wheel, the lever, and the pulley, by which the power of human muscle could be magnified. The next extension
windmills, andбsimple steam-driven devices. More than 2,000 years ago the Chinese developed trip-hammers powered by flowing water and waterwheels. The early АGreeks experimented with simple reaction motors powered by steam. The mechanical clock, representing a rather complex assembly with its own built-in power source (a weight), was developed about 1335 in Europe. Windmills, with mechanisms for automatically
was the development of powered machines that did not require human strength to operate. Examples of these machines include waterwheels,
turning the sails, were developed during the Middle Ages in Europe and the Middle East. The steam engine represented a major advance in the development of powered machines and marked the beginning of the Industrial Revolution. During the two centuries since the introduction of the Watt steam engine, powered engines and machines have been devised that
|
И |
obtain their energy from steam, electricity, and chemical, mechanical, and |
|
nuclear sources. |

Another important development in the history of automation was the Jacquard loom, which demonstrated the concept of a programmable machine. About 1801 the French inventor Joseph-Marie Jacquard devised an automatic loom capable of producing complex patterns in textiles by controlling the motions of many shuttles of different coloured threads. The selection of the different patterns was determined by a program contained in steel cards in which holes were punched. These cards were the ancestors of the paper cards and tapes that control modern automatic machines. The concept of programming a machine was further developed later in the 19th century when Charles Babbage, an English mathematician, proposed a
29
complex, mechanical “analytical engine” that could perform arithmetic and data processing. Although Babbage was never able to complete it, this device was the precursor of the modern digital computer.
