Question

1.Read the passage given below:- What actually is a robot? When different persons have different concepts of robots, the only way of deciding what really is a robot is to look for a definition of the term robot.
The dictionary meaning of a robot is that it is an automatic apparatus or device that performs functions ordinarily ascribed to human beings or operates with what appears to be almost-human intelligence. It is interesting to observe that this meaning does not give a human shape to the robot. In order to dramatise the fact that the robot does the work of a human being, a human shape is given to the robot in science-fiction stories and movies. The human shape is irrelevant as far as the functions of the robot are concerned.
The Robot Institute of America, which is an association of several robot manufacturers gives the following definition of an industrial robot.

The key word in this definition is ‘reprogrammable’. This means that a robot is capable of being reprogrammed. This feature is the one that distinguishes it from a fixed automation. A fixed automation is designed to do one, and only one, specific task. If the specifications of the tasks change even slightly, the fixed automation becomes incapable of performing the task it was designed to perform according to one fixed specification. However, a robot can be reprogrammed to perform even when the specifications are changed drastically. The original program is simply erased and the new program takes care of the changed tasks.

The characteristic that a robot can be reprogrammed to handle a variety of tasks makes the robot a flexible device. Because of the flexibility offered by robots, manufacturing systems which use robots are called Flexible Manufacturing Systems (FMS).

Karel Capek was responsible for introducing the word robot. Sir Isaac Asimov is the one who coined the word robotics. According to Asimov, robotics is the science of dealing with robots. Hence robotics involves a scientific study of robots. The study includes design, selection of materials of proper quality for the components, fabrication, study of various motors required for moving the components, design of electronic circuits, computers and computer programming, and control of robots. Since robots and robotics are still in the developing stages, a considerable amount of research is required and is being pursued. Robotics involves various disciplines-mechanical engineering, material science, electronics, computer science, computer engineering, and control systems, to name just a few. Depending on the area in which robots are to be used, robotics includes disciplines such as biology, medical science, psychology, agriculture, mining, outer space engineering etc.

Basically, there are two types of robots: fixed and mobile. A fixed robot is attached to a stationary platform. A fixed robot is analogous to a human standing or sitting in one fixed location while doing his work with his hands. A mobile robot moves from place to place. Mobility is given to robots by providing wheels or legs or other crawling mechanisms. A mobile robot can be given a human shape, but the actual shape has nothing to do with the functions of the robot. Wheeled locomotion is good for smooth terrains. For rugged terrain, legged locomotion is preferable. A mobile robot should have at least three wheels or legs for stability.

On the basis of your reading of the above passage make notes of it using headings and sub headings. Use abbreviations and write down the summary.​
