A robot is a mechanical or virtual
intelligent agent that can perform tasks automatically or with guidance,
typically by remote control. In practice a robot is usually an
electro-mechanical machine that is guided by computer and electronic
programming. Robots can be autonomous, semi-autonomous or remotely controlled.
Robots range from humanoids such as ASIMO and TOPIO to Nano robots, Swarm
robots, Industrial robots, military robots, mobile and servicing robots. By
mimicking a lifelike appearance or automating movements, a robot may convey a
sense that it has intent or agency of its own. The branch of technology that
deals with robots is robotics.
The word robot was introduced to the public
by the Czech interwar writer Karel Čapek (January 9, 1890 – December 25, 1938) in
his play R.U.R. (Rossum's Universal Robots), published in 1920. The play begins
in a factory that makes artificial people called robots, though they are closer
to the modern ideas of androids, creatures who can be mistaken for humans. They
can plainly think for themselves, though they seem happy to serve. At issue is
whether the robots are being exploited and the consequences of their treatment.
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.
In an article in the Czech journal Lidové
noviny in 1933, he explained that he had originally wanted to call the
creatures laboři ("workers", from Latin labor) or dělňasi (from Czech
dělníci - "workers"). However, he did not like the word, and sought
advice from his brother Josef, who suggested "roboti". The word
robota means literally "corvée", "serf labor", and
figuratively "drudgery" or "hard work" in Czech and also
(more general) "work", "labor" in many Slavic languages
(e.g.: Slovak, Polish, Macedonian, Ukrainian, archaic Czech). Traditionally the
robota was the work period a serf (corvée) had to give for his lord, typically
6 months of the year. The origin of the word is the Old Church Slavonic rabota
"servitude" ("work" in contemporary Bulgarian and Russian),
which in turn comes from the Indo-European root *orbh-. Serfdom was outlawed in
1848 in Bohemia , so at the time Čapek wrote R.U.R., usage of the term robota had
broadened to include various types of work, but the obsolete sense of
"serfdom" would still have been known. It is not clear from which
language Čapek took the radix "robot(a)". This question is not
irrelevant, because its answer could help to reveal an original Čapek´s
conception of robots. If from the modern Czech language, the notion of robot
should be understood as an „automatic serf“ (it means a subordinated creature
without own will). If from e.g. Slovak (Karel Čapek and his brother were
frequent visitors of Slovakia which in this time was a part of Czechoslovakia , because their father MUDr. Antonín Čapek from 1916 worked as a
physician in Trenčianske Teplice, the word robot would simply mean a
„worker“ which is a more universal and neutral notion. The aspect of
pronunciation probably also played a role in Čapek's final decision: In
non-Slavic languages it is easier to pronounce the word robot than dělňas or
laboř.
The word robotics, used to describe this
field of study, was coined by the science fiction writer Isaac Asimov (January
2, 1920 – April 6, 1992). Asimov created the "Three Laws of Robotics"
which are a recurring theme in his books.
The Three Laws of
Robotics (often shortened to The Three Laws or Three Laws). Were introduced in his 1942 short story
"Runaround", although they had been foreshadowed in a few earlier
stories. The Three Laws are:
- A robot may not injure a human being or, through inaction, allow a human being to come to harm.
- A robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law.
- A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.
These form an
organizing principle and unifying theme for Asimov's robotic-based fiction,
appearing in his Robot series, the stories linked to it, and his Lucky Starr
series of young-adult fiction. The Laws are incorporated into almost all of the
positronic robots appearing in his fiction, and cannot be bypassed, being
intended as a safety feature. Many of Asimov's robot-focused stories involve
robots behaving in unusual and counter-intuitive ways as an unintended
consequence of how the robot applies the Three Laws to the situation in which
it finds itself. Other authors working in Asimov's fictional universe have
adopted them and references, often parodic, appear throughout science fiction
as well as in other genres.
The original laws
have been altered and elaborated on by Asimov and other authors. Asimov himself
made slight modifications to the first three in various books and short stories
to further develop how robots would interact with humans and each other; he
also added a fourth, or zeroth law, to precede the others:
0. A robot may not harm humanity, or, by
inaction, allow humanity to come to harm.
