![]() The recent unearthing of the fossil also opens up questions why early Tamils (Thamizh People) needed dentistry. In Mohanjo-daro, the Dravidian civilization was using bow drills for dentistry. Robots are widely used in manufacturing, assembly, packing and packaging, transport, earth and space exploration, surgery, weaponry, laboratory research, safety, and the mass production of consumer and industrial goods. They are also employed in some jobs which are too dirty, dangerous, or dull to be suitable for humans. ![]() ![]() Commercial and industrial robots are widespread today and used to perform jobs more cheaply, more accurately and more reliably, than humans. The first digitally operated and programmable robot, the Unimate, was installed in 1961 to lift hot pieces of metal from a die casting machine and stack them. In 1948 Norbert Wiener formulated the principles of cybernetics, the basis of practical robotics.įully autonomous robots only appeared in the second half of the 20th century. In 1942 the science fiction writer Isaac Asimov created his 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. 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). 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. Īccording 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. 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. Karel Čapek himself did not coin the word. 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.

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.
