The importance of automation and robots in every manufacturing industries keeps growing. Industrial robots have replaced humans inside a wide variety of industries. Robots beat 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 make), assembling, painting, welding, packaging, palletizing, product inspection and testing. Industrial robots are utilized inside 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”. Based on the definition it may be fixed in place or mobile to be used in industrial automation applications. These industrial robots are programmable in 3 or more axes. They’re multi-functional tools that could be custom-built and programmed to carry out a number of operations.

The key benefits of industrial robots is that they might be programmed to suit industry specific requirements which enable it to work continuously for many years, consistently meeting high manufacturing quality standards. The economic expected life associated with an industrial robot is concerning 12-16 years. This can persistent accuracy industrial robots have become an indispensable a part of manufacturing.

Industrial robots are classified into different categories determined by their mechanical structure. The key groups of industrial robots are:

Gantry (Cartesian) Robot: They are stationary robots having three aspects of motion. They work from an overhead grid using a rectangular work envelope. They are mainly employed to perform ‘pick and place’ actions. Gantry robots have their axes higher than the work which makes them also ideal for dispensing applications.
SCARA Robots: (Selectively Compliant Articulated Robot Arm) These robots have 4 axes to move. They move in a x-y-z coordinated circular work envelope. They are utilised 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 well suited to welding, painting and assembly.

Basic industrial robot designs can be customized by having different peripherals. End effectors, optical systems, and motion controllers are crucial add-ons. End effectors would be the end-of-arm-tooling (EOAT) mounted on robotic arms. Grippers or wrenches which can be employed to move or assemble parts are examples of end effectors. End effectors were created and employed to sense and interact with the external environment. The final effectors’ design is dependent upon the application form requirements in the specific industry. Machine Vision systems are robotic optical systems. They’re built-on digital input/output devices and computer networks used to control other manufacturing equipment including robotic arms. Machine vision is used for your inspection of product which for example semiconductor chips. Motion controllers are employed to move robots and position stages smoothly and accurately with sub-micron repeatability.
