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.
Robotics
The word "robotics" was derived from the word "robot", which was introduced to the public by Czech writer Karel Čapek in his play "R.U.R. (Rossum's Universal Robots)", which was published in 1920. The word "robot" comes from the Slavic word "robota", which means labour/work. The play begins in a factory that makes artificial people called "robots", creatures who can be mistaken for humans – very similar to the modern ideas of androids. 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 Josef Čapek as its actual originator.
