the basisof much science fiction. robots are generally used to help with jobs that are too dirty or boring for mosthuman beings.the first prgrammable humanoid robot was about 1206 ad. we can make a robot tolook like almost anything we want. the most fantasized about are ones that have ahumanoid appearance. think of a repetative task and generally there is probably oneon th market that can do what you want. manipulators are the way an object is manipulated. this generally is done bygrippers, or and researchers are constantly trying to hone the robot into somethingbetter.2people who go all lou dobbs about robots. people say things like: all robots lookalike. robots should speak english. robots are taking all the jobs. robots dont payenough taxes. robots reproduce like bunnies. i dont want my child playing with a robot,or goodness gracious, marrying a robot. an acquaintance of mine, who discriminates against robots, but never actuallymet one, received a roomba for christmas i pushed its power button, she said. it wasso cute when it sounded the charge, and scurried across the floor gobbling up dustbunnies. i love roomba, she said. but i still dont like robots. it is typical to thinkthat your robot is somehow different from other robots. those other robots can notbe may take another generation, one where our children are raised amongst robots,for them to gain acceptance. like the washing machine and the automobile, robots arepart of our future.it is true that robots can be hard to tell apart.i remember sarah connor interminator ii. she damn near wet her pants when a series 800-model 101 showed up,a few years after shed sent its twin to the scrap heap. given a little time, however,she got acquainted with the big, muscle-bound machine. she fantasized about keepinghim on as dad and husband. after all, he got along well with the boy, was a good provider,and would stop at nothing to protect her family.although robots are loyal and dependable, they do screw up once in a while. imthinking of hal in XX, a space odyssey. he definitely made a mistake of judgment.i still think he deserved a second chance for every hal, there are dozens of r2-d2sand 3cpos. and that cute little wall-e. occasionally, there is a bad egg, like ed-209 in robocop. or the battle droidsin star wars. but are they worse than rottweilers and pit bulls surely, some of themcan be rehabilitated, and make good an economic point of view, you cant beat robots. they work day and night.they rarely call in sick. they add to the nations gdp, and dont require pensions orhealth care. they are terrific with numbers and rarely have math anxiety. robodocperforms delicate surgeries 24/7 and he never gets the , you ask, what if they go into politics will they impose their culture, theirlanguage, and their way of life on us forget aboutit. no one can resist big macs,vacations to disneyland, and shopping at walmart. this is america.. face it, robots are here to stay. they are willing to do anything. they make greatmaids and gardeners, sweepers and scrubbers, mowers and choppers. there are robotsthat care for the elderly, wash their dirty bottoms and soon perhaps, play yahtzeewith them. there are robots that imitate pets yet dont require walks nor litter boxes.even robots thatll go the fridge, grab a cold beer, and bring it to you. if its eagerto watch the super bowl, and play wii tennis, you got yourself a great far as intermarriage with a robot, didnt they try that in the stepford wivesmaybe it was just too soon. 3most of us are still of of the mindset that robotics is something that is ratherfuturistic. we still may have pictures in our head of humanoid robots, flailing theirarms and either attacking the earth from other planets or perhaps protecting us insome way or another. the fact of the matter is, humanoid robots are still very muchfuturistic but much of the future of robots is already in existence today. robotsare used in a number of different settings that you might find rather interesting.here is a little bit about the future of robotics and the fact that much of it isalready in existence with what we are doing now. one of the ways in which robots are most often used is in an industrial setting.the automotiveindustry, for example, makes use of robots on their assembly lines to do a number of different tasks. unfortunately, this has put many individuals out of a job becausethe robot was able to do what they used to do on the assembly line more efficiently.not only that, once the robot is put into place they are able to take care of theserepetitive tasks, 24 hours a day, 365 days a of the ways in which robotics is used on a regular basis is in spot welding.although this used to require a human touch, much of the welding that is now doneby robots is so accurate and precise that a human could not possibly take care ofit in that way. many times, this welding needs to be done in an assembly lineenvironment so the same simple task is done over and over again. it will be difficultfor anybody to improve on what is already existing in these robotics unless they makethem less apt to have difficulties from breaking down. robots are also able to help us to get out of dangerous situations in many cases.a good example of this is spring painting. humans used to have to take care of spraypainting in the automotive industry and other industrial settings. this put them atrisk because they were constantly being exposed to dangerous chemicals, even if theywore protective clothing. a robot is not only able to be in these rooms without havingto worry about health concerns, they are able todo the painting more evenly andaccurately than their humandeveloping a humanoid robot has long since captured the human imagination andwill be the continued focus in the future of robotics. scientists say there are twoobstacles to creating a robot with human or super-human intelligence: vision andprocessing sensory information. it is almostmotor vehicle production is one area where robotics automation is already beingused. yet imagine a world where we can read, have a glass of wine, talk freely onour cell phones or take a nap while our personal automobile drives itself from ourworkplace to our doorstep. or perhaps well abandon the wheeled prototypes altogetherand kick back in our personal flying car like numerous science fiction films predict.so how far are we from such a future 机器人是机器人的科学技术和应用。
