The value of automation and robots in all manufacturing industries is increasing. Industrial robots have replaced human beings in the wide selection of industries. Robots out perform humans in jobs that need 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 employed in a diverse selection of industries including automotive, electronics, medical, food production, biotech, pharmaceutical and machinery.

The ISO meaning of a manipulating industrial robot is “an automatically controlled, reprogrammable, multipurpose manipulator”. Based on the definition it is usually fixed in place or mobile to use in industrial automation applications. These industrial robots are programmable in three or more axes. They are multi-functional tools that can be custom-built and set to perform selection of operations.

The major aspects of industrial robots is because might be developed to suit industry specific requirements and may work continuously for decades, consistently meeting high manufacturing quality standards. The cost-effective life span of the industrial robot is roughly 12-16 years. Because of the persistent accuracy industrial robots have grown to be an indispensable a part of manufacturing.

Industrial robots are classified into different categories according to their mechanical structure. The major types of industrial robots are:

Gantry (Cartesian) Robot: They are stationary robots having three elements of motion. They work from an overhead grid which has a rectangular work envelope. They are mainly utilized to perform ‘pick and place’ actions. Gantry robots have their axes over the work making them also perfect for dispensing applications.
SCARA Robots: (Selectively Compliant Articulated Robot Arm) These robots have 4 axes of movement. They move in the x-y-z coordinated circular work envelope. They are used for factory automation requiring pick and set work, application and assembly operations and handling machine tools.
Articulated robots: An articulated robot has rotary joints. It might have from two to ten or more interactive joints. Articulated robots are very suitable for welding, painting and assembly.

Basic industrial robot designs might be customized by building different peripherals. End effectors, optical systems, and motion controllers are essential add-ons. End effectors would be the end-of-arm-tooling (EOAT) that come with robotic arms. Grippers or wrenches which are accustomed to move or assemble parts are types of end effectors. End effectors were created and utilized to sense and talk with the external environment. The final effectors’ design depends on the applying requirements in the specific industry. Machine Vision systems are robotic optical systems. These are built-on digital input/output devices and computer networks utilized to control other manufacturing equipment such as robotic arms. Machine vision is utilized for your inspection of product which for example semiconductor chips. Motion controllers are utilized to move robots and position stages smoothly and accurately with sub-micron repeatability.
