ROBOTS IN SL

From Wikipedia, the free encyclopedia (Redirected from Robots) For other uses, see Robot (disambiguation). In Wikipedia, robot may refer to Wikipedia:Bots

TOPIO, a humanoid robot, played ping pong at Tokyo International Robot Exhibition (IREX) 2009.[1][2] Robot

ASIMO (2000) at the Expo 2005, a humanoid robot. A robot is a virtual or mechanical artificial agent. In practice, it is usually an electro-mechanical machine which is guided by computer or electronic programming, and is thus able to do tasks on its own. Another common characteristic is that by its appearance or movements, a robot often conveys a sense that it has intent or agency of its own.

Building the robot of Leonardo da Vinci When civilised societies started, nearly all production and effort was the result of human labour. As mechanical means of performing functions were discovered, and mechanics and complex mechanisms were developed, the need for human labour was reduced. Initially, machinery was used for repetitive functions such as lifting water and grinding grain. With technological advances more complex machines were slowly developed, such as those invented by Hero of Alexandria. They were not widely adopted as human labour, particularly slave labour, was still inexpensive compared to the capital-intensive machines. In the second half of the second millennium man began to develop more complex machines as well as rediscovering the Greek engineering methods. Men such as Leonardo Da Vinci in 1495 through to Jacques de Vaucanson in 1739 have made plans for, and built, automata and robots leading to books of designs such as the Japanese Karakuri zui (Illustrated Machinery) in 1796. As mechanical techniques developed through the Industrial age we find more practical applications such as Nikola Tesla in 1898 who designed a radio-controlled torpedo and the Westinghouse Electric Corporation creation Televox in 1926. From here we find a more android development as designers tried to mimic more human-like features including designs such as those of biologist Makoto Nishimura in 1929 and his creation Gakutensoku, which cried and changed its facial expressions, and the more crude Elektro from Westinghouse in 1938. Electronics now became the driving force of development instead of mechanics with the advent of the first electronic autonomous robots created by William Grey Walter in Bristol, England in 1948. The first digital and programmable robot was invented by George Devol in 1954 and was ultimately called the Unimate. Devol sold the first Unimate to General Motors in 1960 where it was used to lift pieces of hot metal from die casting machines in a plant in Trenton, New Jersey. Since then we have seen robots finally reach a more true assimilation of all technologies to produce robots such as ASIMO which can walk and move like a human. Robots have replaced slaves in the assistance of performing those repetitive and dangerous tasks which humans prefer not to do or unable to do due to size limitations or even those such as in outer space or at the bottom of the sea where humans could not survive the extreme environments. Robots come in those two basic forms: Those which are used to make or move things, such as Industrial robots or mobile or servicing robots and those which are used for research into human-like robots such as ASIMO and TOPIO as well as those into more defined and specific roles such as Nano robots and Swarm robots. Man has developed a fear of the autonomous robot and how it may react in society, such as Shelley's Frankenstein and the EATR, and yet we still use robots in a wide variety of tasks such as vacuuming floors, mowing lawns, cleaning drains, investigating other planets, building cars, entertainment and in warfare.
