									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 testin g.
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
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
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
Industrial robots fill the need for greater precision, reliability,
flexibility and production output in the increasingly competitive and
complex manufacturing industry environment.
