The value of automation and robots in all manufacturing industries is growing. Industrial robots have replaced human beings in the wide selection of industries. Robots beat humans in jobs which need precision, speed, endurance and reliability. Robots safely perform dirty and dangerous jobs. Traditional manufacturing robotic applications include material handling (pick and set), assembling, painting, welding, packaging, palletizing, product inspection and testing. Industrial robots are widely-used in the diverse variety 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”. In accordance with the definition it can be fixed in place or mobile to use in industrial automation applications. These industrial robots are programmable in a variety of axes. They are multi-functional pieces of equipment that may be custom-built and set to execute a various operations.

The key advantages of industrial robots is they may be set to suit industry specific requirements and will work continuously for many years, consistently meeting high manufacturing quality standards. The economic lifespan of the industrial robot is concerning 12-16 years. This can persistent accuracy industrial robots are becoming variety a part of manufacturing.

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

Gantry (Cartesian) Robot: They’re stationary robots having three components of motion. They work from an overhead grid having a rectangular work envelope. They’re mainly used to perform ‘pick and place’ actions. Gantry robots have all their axes above the work making them also well suited for dispensing applications.
SCARA Robots: (Selectively Compliant Articulated Robot Arm) These robots have 4 axes of motion. They move in a x-y-z coordinated circular work envelope. They are utilized 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 might have from two to ten or maybe more interactive joints. Articulated robots are very suited to welding, painting and assembly.

Basic industrial robot designs might be customized with the addition of different peripherals. End effectors, optical systems, and motion controllers are essential add-ons. End effectors would be the end-of-arm-tooling (EOAT) attached to robotic arms. Grippers or wrenches which are accustomed to move or assemble parts are samples of end effectors. End effectors are designed and used to sense and connect to the external environment. The finish effectors’ design depends on the application form requirements with the specific industry. Machine Vision systems are robotic optical systems. They are built-on digital input/output devices and computer networks accustomed to control other manufacturing equipment like robotic arms. Machine vision is used for your inspection of manufactured goods including semiconductor chips. Motion controllers are utilized to move robots and position stages smoothly and accurately with sub-micron repeatability.
