Robot
In 1928, one of the first humanoid robots, Eric, was exhibited at the annual exhibition of the Model Engineers Society in London, where it delivered a speech. Invented by W. H. Richards, the robot's frame consisted of an aluminium body of armour with eleven electromagnets and one motor powered by a twelve-volt power source. The robot could move its hands and head and could be controlled through remote control or voice control. Both Eric and his "brother" George toured the world.
Robots in literature
While Karel Čapek's play introduced the word "robot" into languages around the globe but he later wrote a letter to the Oxford English Dictionary of etymology in which he named his brother, painter and writer Josef Čapek, as its true inventor. In an article in the Czech Lidové noviny in 1933 he also explains that he originally wanted to call the creatures "laboři" from the Latin word "labor". Karel found the word too bookish and sought advice from Josef who suggested to call them "robots". The word, which is always capitalized in Čapek's play, derives from "robota" which means "drudgery" in Czech and means "work" in Slovak.)
