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.
Science fiction film
Robots have been a part of science fiction since the Czech playwright Karel Čapek coined the word in 1921. In early films, robots were usually played by a human actor in a boxy metal suit, as in "The Phantom Empire", although the female robot in "Metropolis" is an exception. The first depiction of a sophisticated robot in a United States film was Gort in "The Day the Earth Stood Still".
