The term robot itself is derived from the Czech word robota, meaning «compulsory labour».
Some of the «robots» used in advertising and entertainment are actually automata, even with the addition of remote radio control. Today the term automatonis usually applied to these handcrafted, mechanical (rather than electromechanical) devices that imitate the motions of living creatures. Such automata also appeared in the clockwork figures of medieval churches, and in the 18th century some clockmakers gained fame for the clever mechanical figures that they constructed. The concept of robots dates back to ancient times, when some myths told of mechanical beings brought to life. Programmable assembly machines are represented by the component-insertion machines employed in the electronics industry. Assembly machines of this type are considered to be examples of fixed automation, because they are generally configured for a particular product made in high volume. A new component is added to the partially completed product at each workstation, thus building up the product gradually as it proceeds through the line. Typical workheads include automatic screwdrivers, welding heads and other joining devices. A workhead at each station performs the actual attachment of the component. A typical assembly machine consists of several stations, each equipped with a supply of components and a mechanism for delivering the components into position for assembly.
#HISTORY OF AUTOMATION IN IT MANUAL#
For products that do not satisfy these conditions, manual assembly is generally required.Īutomated assembly machines have been developed that operate in a manner similar to machining transfer lines, with the difference being that assembly operations, instead of machining, are performed at the workstations. Assembly operations can be automated using production line principles if the quantities are large, the product is small, and the design is simple (e.g., mechanical pencils, pens, and cigarette lighters).
Owing to the high labour content and high cost of manual labour, greater attention has been given in recent years to the use of automation for assembly work. Assembly operations have traditionally been performed manually, either at single assembly workstations or on assembly lines with multiple stations.
