					Automation and Industrial Robots The importance of automation and robots in all
manufacturing industries is growing. Industrial robots have replaced human beings in a
wide variety of industries. Robots out perform humans in jobs that require precision,
speed, endurance and reliability. Robots safely perform dirty and dangerous jobs.
Traditional manufacturing robotic applications include material handling (pick and
place), assembling, painting, welding, packaging, palletizing, product inspection and
testing. Industrial robots are used in a diverse range of industries including automotive,
electronics, medical, food production, biotech, pharmaceutical and machinery. The ISO
definition of a manipulating industrial robot is "an automatically controlled,
reprogrammable, multipurpose manipulator". According to the definition it can be fixed
in place or mobile for use in industrial automation applications. These industrial robots
are programmable in three or more axes. They are multi-functional pieces of equipment
that can be custom-built and programmed to perform a variety of operations. The major
advantages of industrial robots is that they can be programmed to suit industry specific
requirements and can work continuously for years, consistently meeting high
manufacturing quality standards. The economic life span of an industrial robot is
approximately 12-16 years. Due to their persistent accuracy industrial robots have
become an indispensable part of manufacturing. Industrial robots are classified into
different categories based on their mechanical structure. The major categories of
industrial robots are: Gantry (Cartesian) Robot: They are stationary robots having three
elements of motion. They work from an overhead grid with a rectangular work envelope.
They are mainly used to perform 'pick and place' actions. Gantry robots have all their
axes above the work making them also ideal for dispensing applications. SCARA Robots:
(Selectively Compliant Articulated Robot Arm) These robots have 4 axes of motion.
They move within an x-y-z coordinated circular work envelope. They are used for factory
automation requiring pick and place work, application and assembly operations and
handling machine tools. Articulated robots: An articulated robot has rotary joints. It can
have from two to ten or more interactive joints. Articulated robots are well suited to
welding, painting and assembly. Basic industrial robot designs can be customized with
the addition of different peripherals. End effectors, optical systems, and motion
controllers are essential add-ons. End effectors are the end-of-arm-tooling (EOAT)
attached to robotic arms. Grippers or wrenches that are used to move or assemble parts
are examples of end effectors. End effectors are designed and used to sense and interact
with the external environment. The end effectors' design depends on the application
requirements of the specific industry. Machine Vision systems are robotic optical
systems. They are built-on digital input/output devices and computer networks used to
control other manufacturing equipment such as robotic arms. Machine vision is used for
the inspection of manufactured goods such as semiconductor chips. Motion controllers
are used to move robots and position stages smoothly and accurately with sub-micron
repeatability. Industrial robots fill the need for greater precision, reliability, flexibility and
production output in the increasingly competitive and complex manufacturing industry
environment. AESG, Automation Equipment Services Group Inc. - experts in automation
