In 1920, when Karel Capek wrote the three-act play R.U.R. (Rossum’s Universal Robots) he probably didn’t realize he would be changing humanity’s conception of what it is to be alive for generations to come, much less had the word “robot” to the world’s collective glossary.
Derived from the Slavic term “robota”, meaning the work done by an indentured servant, robots have gone on to become a staple of science-fiction. We take their functions and existence for granted, with our own efforts at robotics ranging from industrial mechanical arms to the new wave of lovely Japanese automata.
According to our age group, we look back fondly at either Robbie the Robot or Artoo-Detoo and See-Threepio. Perhaps some even remember seeing the graceful “María” making her appearance for the first time in Fritz Lang’s Metropolis.
Only a year after “R.U.R.” appeared on the stage, French director André Deed created one of the first science-fiction movies involving robots: L’uomo Meccanico (The Mechanical Man), depicting a giant humanoid robot created for criminal purposes, but who is checked by another equally sizeable machine, settling their differences inside an Italian opera house.
These original “rock’em-sock’em robots” showed audiences that the mechanical men, while emotionless, could serve the cause of good as well as evil.
