What is a robot?
Let's define the term: Robot. It means slave labourer, with its root in the Czech word “robota”. They are just like a servant. If we are going to give some tasks to the robot, it is going to perform those tasks just like a servant.
Who coined the Term?
The term was introduced in the year 1921 by Karel Capek a Czech playwright. In a particular drama, he introduced a term: robota, that is, the robot. But, the way he described a robot is as follows: the robot was look-wise similar to a human being.
But, nowadays we use a few robots, which do not look like a human being. So, this is the way actually, the term robot was introduced in the year 1921. But, during that time, there was not even a single robot in the world. The robot is an automatically controlled machine. And, it is reprogrammable that means the same robot can be made to do a variety of task.
