All About Robotics

The word robot has been derived from a Czech word ‘robota’ that means ‘drudgery’. A robot can be defined as a machine operated by computer programs that can perform small actions. They can be programmed to do various things. The field in which we study robots is known as Robotics.

Mostly robots are used to do jobs that involve repetitive actions or dangerous jobs that cannot be done by humans. You must have watched sci-fi movies and are surely fascinated with those robotic characters, but real life robots are way different from those extra smart machines .
