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
According to the "Oxford English Dictionary", the word "robotics" was first used in print by Isaac Asimov, in his science fiction short story ""Liar!"", published in May 1941 in "Astounding Science Fiction". Asimov was unaware that he was coining the term; since the science and technology of electrical devices is "electronics", he assumed "robotics" already referred to the science and technology of robots. In some of Asimov's other works, he states that the first use of the word "robotics" was in his short story "Runaround" (Astounding Science Fiction, March 1942), where he introduced his concept of The Three Laws of Robotics. However, the original publication of "Liar!" predates that of "Runaround" by ten months, so the former is generally cited as the word's origin.
