Automation at its basic level can be expressed simply with the statement that analyses that were traditionally manually performed are now performed mechanically through computer-controlled robotics or workstations. Designers typically have a strong desire to exactly reproduce the manual process. In reality, minor changes to the manual approach must be made in order to make the automated process reliable and efficient. 

Note Accdg to Dutton (Ref 58, pp 141-43), the Repauno Plant manufd Dynamite until 1954, when it was converted to chemicals. There were in 1960 other du Pont Dynamite plants, the largest located on the Potomac River near Mar-tinsburg, W. Virginia. It was operated by remote control robots... 

We chose a general view because the impact of computers on flavor and fragrance research is not limited to a particular area. The advent of the microprocessor has made powerful, inexpensive microcomputers available to the analytical chemist and the sensory scientist alike. These people have connected them to their machines, used them to control robots, and placed them in their sensory evaluation booths. The successful development of inexpensive memory and very fast central processing units, on the other hand, has made very powerful minicomputers available to the computational chemist and the information scientist. These researchers now routinely use the computer to design new functional molecules, design new products, and keep track of huge collections of molecules and associated data. 

The library design software, Library Studio , is part of a suite of software applications, Renaissance , developed at Symyx to design experiments, control robotics, integrate and control analytical devices, and capture and search experimental designs, methods, and data. 

Machine process controls coordinate individual functions of the clamp, injection unit, ejector mechanism, and mold systems and accessories such as core pulls and unscrewing dies for threaded parts. The more advanced controls employ a feedback system (closed loop) to provide much tighter control over actual parameters vs. setpoints. High-level controls are capable of communicating with auxiliary equipment such as chillers, hopper loaders, mold temperature controllers, robots, etc., and displaying all machine parameters and conditions (Chapter 3)...

Profile This privately held company was founded in 1993 to integrate advanced technologies in structure-based design, combinatorial chemistry, and chemi-informatics for the cost-effective discovery of orally active pharmaceuticals. The company has developed a system capable of generating new drugs through computer-controlled robotic synthesis and analysis of chemical libraries. Current drug discovery efforts are focused on cardiovascular disease and cancer. 

Measures 1-4 indicate efficiency in the use of people measure 5 indicates efficiency in the use of capital and measure 6 indicates efficiency in the use of raw materials. These are partial-productivity measures. To obtain an idea of total productivity, all ratios must be considered rather than the efficiency of one particular input. There are some trade-offs, such as using automatic equipment (automatic controls, robots, etc.) instead of operators. An industry may be very efficient in the use of people but less efficient in the use of capital. Rather than absolute productivity ratios for an industry, the trend in productivity ratios is important. Rising productivity is the key to economic growth, and the increase in output per employee pays for increases in salaries and wages.

An order picking warehouse has different problems to the more conventional bulk warehouse. Goods are picked from racking or bins, either by hand or lately by more sophisticated electronically controlled robotic systems for despatch. Depending on the warehouse type, the journey may be long distance by lorry with manual and/or mechanical handling in example A above, or into a basket into the back of a van in example B. 

Manual sorting can be efficiently followed by automated ranking utilizing identification by infrared radiation or visible radiation (to separate colors). Identification software controls robots (robots or air flow) which perform the selective removal of objects according to their nature. 

Servo-controlled robots are run in a "closed loop . A feedback control system is used to drive the robot to certain sequenced desired points. Normally the robots are run with a limited accuracy therefore the final position is determined by an error signal. The error signal is created by the difierence between the manipulator s momentary position and the position the manipulator is to be directed. The closed-loop servo system continuously minimizes the error signal and drives the manipulator to keep the positioning error as small as possible.
