The utilization of robots, controlled systems and newer technologies for performing various tasks and operations as method to reduce indulgence of human workforce is known as automation. Various industries such as automotive, oil & gas, electrical, food & beverages, pharmaceutical, machine tending and chemicals among others are at the forefront of adopting industrial automation in their factories. The prolong technical advancement with the integration of machine vision, high performance processors, analytical software, and sensors among others is helping industries to adopt automation at full potential. High accuracy, low maintenance and overhead cost is the prime driver of industrial automation. Application of internet of things IoT technologies would help industries to achieve lean production process to increase output capacity. Industry 4.0 gyrates around the current factory automation trends and data exchange encompassing cloud computing, cyber-physical systems and IoT. The rudimentary of this concept is to encompass algorithms of machine learning that necessitates none or minimal human intervention, where the cyber physical systems observes the processes and communicate with each other and human interfaces in real time through wireless communication technologies. Few of the leading player pertaining in the industry are Rockwell, Yokogawa, Emerson, Honeywell, Fanuc and GE among others.
