The importance of automation and robots in all constructing industries is growing. Industrial robots have exchanged human beings in a wide form of industries. Robots out execute humans in jobs that require precision, speed, survival and reliableness. Robots safely perform dirty and dangerous jobs. Traditional making up robotic applications let in material handling (pick and place), assembling, painting, welding, packaging, palletizing, product inspection and examining.
Industrial robots are applied in a diverse range of industries letting in automotive, electronics, medical, food production, biotech, pharmaceutical and machinery. The ISO definition of a manipulating industrialised robot is “an mechanically assured, reprogrammable, multipurpose manipulator”. According to the definition it can be set in place or mobile for use in industrial automation applications. These industrialized robots are programmable in three or more axes. They are multi-functional pieces of equipment that can be custom-built and programmed to execute a variety of procedures. The major rewards of industrial robots is that they can be programmed to fit industry specific requirements and can work continuously for years, consistently meeting high manufacture quality standards. The economical life span of an industrial robot is more or less 12-16 years. Due to their persistent accuracy industrialized robots have become an indispensable part of manufacturing. Industrial robots are separated into another categories situated on their mechanic structure. The major categories of industrial robots are:
Gantry (Cartesian) Robot: They are stationary robots having three ingredients of movement. They make from an overhead power grid with a rectangular work envelope. They are mainly in use to execute ‘pick and place’ actions. Gantry robots have all their axes above the work holding them also ideal for dispensing applications.
SCARA Robots: (Selectively Compliant Articulated Robot Arm) These robots have 4 axes of movement. They travel within an x-y-z integrated circular work envelope. They are applied for factory automation expecting pick and place work, application and gathering operations and handling machine tools.
Formulated 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 controls are required add-ons. End effecter are the end-of-arm-tooling (EOAT) attached to robotic arms. Grippers or pulls that are in use to move or assemble parts are examples of end effectors. End effectors are designed and in use to sense and interact with the overseas environment. The end effectors’ design counts on the application essentials of the particular industry. Machine Vision systems are robotic visual 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 practiced for the inspection of ready-made 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 require for larger precision, reliability, flexibility and production output in the more and more competitive and complex constructing industry environs.
