A robot is a mechanical or virtual
agent, usually an electro-mechanical
machine that is guided by a computer
program or electronic circuitry. Robotics is
the branch of technology that
deals with the design, construction, operation, and application of
robots, as well as computer systems for their control, sensory feedback,
and information processing. These technologies deal with automated machines that
can take the place of humans in dangerous environments or manufacturing
processes, or resemble humans in appearance, behavior, and/or cognition. Many
of today's robots are inspired by nature contributing to the field of bio-inspired
robotics.
Robot
is very famous thing for this new era. All people now try to make new inovation
about new technology. They study hard and sometimes use a lot of money to learn
about robotic. Robot is everything, robot is new thing, robot can do anything.
These’re in their mind. Robot is the most important, robot is the new future
for this world. Now every human have to learn about technology, specially about
robotic. Intelligence robot still in the research. Now almost all modern
factory in the world use robot for their production. Make it perfect, minimize
errors that occur.
The idea of automata originates in the mythologies of
many cultures around the world. Engineers and inventors from ancient
civilizations, including Ancient China, Ancient Greece, and Ptolemaic Egypt, attempted to
build self-operating machines, some resembling animals and humans. Early descriptions
of automata include the artificial doves ofArchytas, the
artificial birds of Mozi and Lu Ban, a
"speaking" automaton by Hero of Alexandria, a washstand automaton by Philo of Byzantium, and a human automaton described in the Lie Zi.
Many
ancient mythologies, and most modern religions include artificial people, such
as the mechanical servants built by the Greek god Hephaestus (Vulcan to the Romans), the clay golems of Jewish
legend and clay giants of Norse legend, and Galatea, the
mythical statue of Pygmalion that came to life. Since circa 400 BC, myths
of Crete include Talos, a man of bronze who guarded the
Cretan island of Europa from pirates.
In ancient Greece, the Greek engineer Ctesibius (c. 270 BC) "applied a knowledge of
pneumatics and hydraulics to produce the first organ and water clocks with moving
figures." In the 4th century BC, the Greek mathematician Archytas of Tarentum postulated a mechanical
steam-operated bird he called "The Pigeon". Hero of
Alexandria(10–70 AD), a G reek mathematician and inventor, created numerous user-configurable
automated devices, and described machines powered by air pressure, steam and
water.
The 11th century Lokapannatti tells of how
the Buddhas relics were protected by mechanical robots (bhuta vahana yanta),
from the kingdom of Roma visaya (Rome); until they were disarmed by King Ashoka.
In ancient China, the 3rd century text of the Lie Zi describes an account of humanoid
automata, involving a much earlier encounter between Chinese emperor King Mu of Zhou and a mechanical engineer known as Yan Shi,
an 'artificer'. Yan Shi proudly presented the king with a life-size,
human-shaped figure of his mechanical 'handiwork' made of leather, wood, and
artificial organs. There are also accounts of flying automata in the Han Fei Zi and other texts, which attributes the
5th century BC Mohist philosopher Mozi and his
contemporary Lu Ban with the
invention of artificial wooden birds (ma yuan) that could successfully
fly. In 1066, the Chinese inventor Su Song built a water clock in the form of a tower which featured
mechanical figurines which chimed the hours.
The beginning of automata is associated with
the invention of early Su Song's astronomical clock tower featured mechanical
figurines that chimed the hours. His
mechanism had a programmable drum machine with pegs (cams) that bumped
into little leve rs that operated percussion instruments. The
drummer could be made to play different rhythms and different drum patterns by
moving the pegs to different locations.
