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.

Karel Čapek himself did not coin the word. He wrote a short letter in reference to an etymology in the "Oxford English Dictionary" in which he named his brother, the painter and writer Josef Čapek, as its actual originator.
