The significance of automation and robots in most manufacturing industries continues to grow. Industrial robots have replaced human beings in the wide range 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 utilized within a diverse array 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 can be fixed in place or mobile to use in industrial automation applications. These industrial robots are programmable in 3 or more axes. They’re multi-functional devices that may be custom-built and programmed to execute a number of operations.

The key benefits associated with industrial robots is they could be designed to suit industry specific requirements and will work continuously for a long time, consistently meeting high manufacturing quality standards. The economic life time associated with an industrial robot is concerning 12-16 years. Due to their persistent accuracy industrial robots are getting to be variety part of manufacturing.

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

Gantry (Cartesian) Robot: They’re stationary robots having three aspects of motion. They work from an overhead grid which has a rectangular work envelope. These are mainly employed to perform ‘pick and place’ actions. Gantry robots supply their axes across the work which makes them also ideal 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 utilised for factory automation requiring pick make work, application and assembly operations and handling machine tools.
Articulated robots: An articulated robot has rotary joints. It might have from two to 10 or maybe more interactive joints. Articulated robots are very suited to welding, painting and assembly.

Basic industrial robot designs could be customized by having different peripherals. End effectors, optical systems, and motion controllers are essential add-ons. End effectors will be the end-of-arm-tooling (EOAT) attached to robotic arms. Grippers or wrenches which can be used to move or assemble parts are examples of end effectors. End effectors were created and utilized to sense and interact with the external environment. The final effectors’ design is dependent upon the approval requirements with 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 manufactured goods like semiconductor chips. Motion controllers are widely-used to move robots and position stages smoothly and accurately with sub-micron repeatability.
