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.
Liar! (short story)
"Liar!" is a science fiction short story by American writer Isaac Asimov. It first appeared in the May 1941 issue of "Astounding Science Fiction" and was reprinted in the collections "I, Robot" (1950) and "The Complete Robot" (1982). It was Asimov's third published positronic robot story. Although the word "robot" was introduced to the public by Czech writer Karel Čapek in his 1920 play "R.U.R." (Rossum's Universal Robots), Asimov's story "Liar!" contains the first recorded use of the word "robotics" according to the "Oxford English Dictionary". The events of this short story are also mentioned in the novel "The Robots of Dawn" written by the same author.
