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.

According to the "Oxford English Dictionary," the first passage in Asimov's short story "Liar!" (1941) that mentions the First Law is the earliest recorded use of the word "robotics". Asimov was not initially aware of this; he assumed the word already existed by analogy with "mechanics," "hydraulics," and other similar terms denoting branches of applied knowledge.
