Robotics is the science that deals with the technology of robots, their design, manufacture, and application. Robtoics is synonomous with automation.
Robots are mainly used for carrying materials including heavy parts to and from inconvenient locations and handling hazardous materials like nuclear waste. The benefit of robot is that they never get tired or exhausted. The mechanization in processing of Robotics is divided into 3 types and they are hard, programmable and flexible.
In the Hard type, the series of processing opertaions is fixed by the structure or configuration of the equipment used in. The significant characterestic of the hard type is the high capital investment as ion automobile assembly line. In programmable Automation, the same tools can be reprogrammed to suit the requirement of diverse types of products. And in flexible automation, the reprogramming is done offline. The 2 vital elements of robtoics are numerical control and tele-operations. The 2 technologies of numerical control of tele-operation are combined in industrial robots.
It is seen that facilities are found in institutions such as IIT's for research oriented work in this discipline, typically as part of PG programmes.
you can go for a PCM with computer science if you are interested in robotics... the scope of this field will only increase in the future as humans become more and more dependant on machines..also we are constantly discovering new areas of reasearch where it is humanly impossible to go..for example outer space..so we take the help of robots ...after doing a bachelors degree in engineering prefferentially mechanical or electrical..you can opt for a wide range of robotics involved fields ..such as maintstream robotics or nanotech etc.

Scope and Limitations of Robots
In basic robotics we design machines to do the specified tasks and in the advanced version of it robots are designed to be adaptive, that is, respond according to the changing environment and even autonomous, that is, capable to make decisions on their own. While designing a robot the most important thing to be taken in consideration is, obviously, the function to be performed. Here comes into play the discussion about the scope of the robot and robotics. Robots have basic levels of complexity and each level has its scope for performing the requisite function.
The levels of complexity of robots is defined by the members used in its limbs, number of limbs, number of actuators and sensors used and for advanced robots the type and number of microprocessors and microcontrollers used. Each increasing component adds to the scope of functionality of a robot. With every joint added, the degrees of freedom in which a robot can work increases and with the quality of the microprocessors and microcontrollers the accuracy and effectiveness with which a robot can work is enhanced.
To understand the scope for any robot of given complexity, we will discuss it with a very simple example. Consider a robot comprising of one member joined to the base with a revolute joint and a servo motor is connected to that revolute joint which is controlled by a microcontroller programmed to move the member through a certain degrees of rotation. This is the most basic robot which I could think of.
Scope: The motion of this robotic arm is restricted to a circular path. Any task which can be done by the motion along the circular arc can be performed by this robot. Say, we want to draw arcs on sheets of papers or we want to cut them in circular pieces that can be achieved by fitting a pencil and a cutter to the end of this robotic arm.
Limitation: Any point on this robotic arm can only move along a circular path. Any task involving motion other that the circular motion cannot be performed by such robot.
Scope of robots can be extended and limitations can be reduced by adding to the complexity of the robots. One can imagine of the possibilities of motions which can arise by simply adding one more limb to the existing one through a revolute joint and a servo motor. This is a very basic example; in fact, robotics is very vibrant field with infinite scope and an equal numbers of limitations ever reducing.
