Final answer:
The word 'robot' comes from the Czech word 'robota', introduced by Czech playwright Karel Čapek in the 1920 play 'R.U.R.' Robots today are part of a field called robotics, which has both commercial and industrial applications.
Step-by-step explanation:
The term robot originated from the Czech word robota, which means forced labor or servitude. The word was first introduced to the public in the 1920 play 'R.U.R.' (Rossum's Universal Robots) by Czech playwright Karel Čapek. His brother, Josef Čapek, is credited with coining the term. Robots have since transitioned from science fiction to reality, and the study and creation of robots is now known as robotics. This field encompasses the design, construction, operation, and use of robots, with applications ranging from domestic aids like autonomous vacuum cleaners to more complex industrial and service robots. The term was first introduced in a play called "R.U.R." (Rossum's Universal Robots) by Czech writer Karel Čapek in 1920.
