History of robot (Last part)
Medieval developments
Al-Jazari (1136-1206), an Arab Muslim inventor during the Artuqid dynasty, designed and constructed a number of automatic machines, including kitchen appliances, musical automata powered by water, and the first programmable humanoid robot in 1206. Al-Jazari’s robot was a boat with four automatic musicians that floated on a lake to entertain guests at royal drinking parties. His mechanism had a programmable drum machine with pegs (cams) that bump into little levers that operate the percussion. The drummer could be made to play different rhythms and different drum patterns by moving the pegs to different locations.
One of the first recorded designs of a humanoid robot was made by Leonardo da Vinci (1452-1519) in around 1495. Da Vinci’s notebooks, rediscovered in the 1950s, contain detailed drawings of a mechanical knight able to sit up, wave its arms and move its head and jaw. The design is likely to be based on his anatomical research recorded in the Vitruvian Man. It is not known whether he attempted to build the robot
Early modern developments
An early automaton was created in 1738 by Jacques de Vaucanson, who created a mechanical duck that was able to eat and digest grain, flap its wings, and excrete.
The Japanese craftsman Hisashige Tanaka, known as “Japan’s Edison,” created an array of extremely complex mechanical toys, some of which were capable of serving tea, firing arrows drawn from a quiver, or even painting a Japanese kanji character. The landmark text Karakuri Zui (Illustrated Machinery) was published in 1796. (T. N. Hornyak, Loving the Machine: The Art and Science of Japanese Robots [New York: Kodansha International, 2006])
Modern Developments
In the 1930s, Westinghouse Electric Corporation made a humanoid robot known as Elektro, exhibited at the 1939 and 1940 World’s Fairs.
The first electronic autonomous robots were created by William Grey Walter of the Burden Neurological Institute at Bristol, England in 1948 and 1949. They were named Elmer and Elsie. These robots could sense light and contact with external objects, and use these stimuli to navigate.
It wasn’t until the second half of the twentieth century, when integrated circuits were invented, and computers began to double rapidly in power (roughly every two years according to Moore’s Law),[25] that it became possible to build robots as we imagine them. Until that time, automatons were the closest things to robots, and while they may have looked humanoid, and their movements were complex, they were not capable of the self-control and decision making that robots are today.
The first truly modern robot, digitally operated, programmable, and teachable, was invented by George Devol in 1954 and was ultimately called the Unimate. It is worth noting that not a single patent was cited against his original robotics patent (U.S. Patent 2,988,237 ). The first Unimate was personally sold by Devol to General Motors in 1960 and installed in 1961 in a plant in Trenton, New Jersey to lift hot pieces of metal from a die casting machine and stack them.
