Automation (ancient Greek: = self dictated) or industrial automation or numerical control is the use of control systems such as computers to control industrial machinery and processes, replacing human operators. In the scope of industrialization, it is a step beyond mechanization. Whereas mechanization provided human operators with machinery to assist them with the physical requirements of work, automation greatly reduces the need for human sensory and mental requirements as well.
History of automation
Early machines were simple machines that substituted one form of effort with a more humanly manageable effort, as lifting a large weight with a system of pulleys or a lever. Later machines were also able to substitute natural forms of renewable energy, such as wind, tides, or flowing water, for human energy. The sailboat replaced the paddled or oared boat. Still later, early forms of automation were driven by clock type mechanisms or similar devices using some form of artificial power source— a wound-up spring, channelled flowing water, or steam— to produce some simple, repetitive action, such as moving figures, making music, or playing games. Such early moving devices, featuring human-like figures, were known as automatons and date from perhaps 300 BC). In 1801, the patent was issued for the automated loom using punched cards. This invention by Joseph Marie Jacquard revolutionized the textile industry.
The most visible part of modern automation can be said to be industrial robotics. Some advantages are repeatability, tighter quality control, higher efficiency, integration with business systems, increased productivity and reduction of labor. Some disadvantages are high capital requirements, severely decreased flexibility, and increased dependence on maintenance and repair. For example, Japan had to scrap many of its industrial robots when they were found to be incapable of adaptation to substantially changed production requirements and so not necessarily able to justify their high initial costs.
By the middle of the 20th century, automation had existed for many years on a small scale, using simple mechanical devices to automate simple manufacturing tasks. However the concept only became truly practical with the addition (and evolution) of the digital computer, whose flexibility allowed it to drive almost any sort of task. Digital computers with the required combination of speed, computing power, price, and size first started to appear in the 1960s. Before that time, industrial computers were almost exclusively analog computers and hybrid computers. Since then digital computers have taken over control of the vast majority of simple, repetitive tasks, and ever more semi-skilled and skilled tasks, with some food production and inspection being a notable exception. As anonymous so famously remarked, "for very many rapidly changing tasks, it is difficult to replace human beings, who are so easily retrainable within a wide range of tasks and, moreover, so inexpensively produced by unskilled labor."

Automation (ancient Greek: = self dictated), roboticization[1] or industrial automation or numerical control is the use of control systems such as computers to control industrial machinery and processes, replacing human operators. In the scope of industrialization, it is a step beyond mechanization. Whereas mechanization provided human operators with machinery to assist them with the physical requirements of work, automation greatly reduces the need for human sensory and mental requirements as well.

No matter which country, industrial automation is like use of alternative energy: It is driven by a need, not so much because it makes sense. As long as there are millions of "cheap workers" in India, there is not much of a "need".
Exceptions are industries where manual labour just can't do the job, like micro-electronics, surface mount technology, and alike.
But India is not really known to be at the forefront of those....

Go for some PG course in Indutrial automation. Industrial automation is automation of various machines in hyfraulic or pnematic designs with the help of electric motors.The demand i svery good. Its a subjec tof mechanical engineering
