(Rossum’s Universal Robots), which premiered in 1921. 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. 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. History of Robotics Three Laws of Robotics: * Law One: A robot may not injure a human being, or, through inaction, allow a human being to come to harm. * Law Two: A robot must obey orders given it by human beings, except when such orders would conflict with the first law. * Law Three: A robot must protect its own existence, as long as such protection does not conflict with the first or second law. History of Robotics early robots (1940's - 50's) Grey Walter's "Elsie the "Shakey" The General Electric Walking tortoise" Stanford Research Truck the first legged vehicle Institute in the with a computer-brain, by Ralph 1960s. Moser at General Electric Corp. in the 1960s. History of Robotics The first modern industrial robots were probably the "Unimates", created by George Devol and Joe Engleberger in the 1950's and 60's. Engleberger started the first robotics company, called "Unimation", and has been called the "father of robotics." History of Robotics Isaac Asimov and Joe Engleberger (image from Robotics Society of America web site) History of Robotics EXPLORATION People are interested in places that are sometimes full of danger, like outer space, or the deep ocean. But when they can not go there themselves, they make robots that can go there. The robots are able to carry cameras and other instruments so that they can collect information and send it back to their human operators History of Robotics INDUSTRY When doing a job, robots can do many things faster than humans. Robots do not need to be paid, eat, drink, or go to the bathroom like people. They can do repetative work that is absolutely boring to people and they will not stop, slow down, or fall to sleep like a human. History of Robotics MEDICINE Sometimes when operating, doctors have to use a robot instead. A human would not be able to make a hole exactly one 100th of a inch wide and long. When making medicines, robots can do the job much faster and more accurately than a human can. Also, a robot can be more delicate than a human. History of Robotics MEDICINE Some doctors and engineers are also developing prosthetic (bionic) limbs that use robotic mechanisms. History of Robotics MILITARY and POLICE Police need certain types of robots for bomb-disposal and for bringing video cameras and microphones into dangerous areas, where a human policeman might get hurt or killed. The military also uses robots for (1) locating and destroying mines on land and in water, (2) entering enemy bases to gather information, and (3) spying on enemy troops. History of Robotics TOYS The new robot technology is making interesting types of toys that children will like to play with. One is the "LEGO MINDSTORMS" robot construction kit. These kits, which were developed by the LEGO company with M.I.T. scientists, let kids create and program their own robots. Another is "Aibo" - Sony Corporation's robotic dog.
