2、mpr(总题数：1，分数：70.00)Trust Me, I Am a RobotRobot safety: as robots move into homes and offices, ensuring that they do not injure people will be vital. But how?The incidentIn 1981 Kenji Urada, a 37-year-old Japanese factory worker, climbed over a safety fence at a Kawasaki plant to carry out some maint
3、enance work on a robot. In his haste, he failed to switch the robot off properly. Unable to sense him, the robots powerful hydraulic arm kept on working and accidentally pushed the engineer into a grinding machine. His death made Urada the first recorded victim to die at the hands of a robot.This gr
4、uesome industrial accident would not have happened in a world in which robot behaviour was governed by the Three Laws of Robotics drawn up by Isaac Asimov, a science-fiction writer. The laws appeared in I, Robot, a book of short stories published in 1950 that inspired a recent Hollywood film. But de
5、cades later the laws, designed to prevent robots from harming people either through action or inaction, remain in the realm of fiction.Indeed, despite the introduction of improved safety mechanisms, robots have claimed many more victims since 198 I. Over the years people have been crushed, hit on th
6、e head, welded and even had molten aluminium poured over them by robots. Last year there were 77 robot-related accidents in Britain alone, according to the Health and Safety Executive.More related issuesWith robots now poised to emerge from their industrial cages and to move into homes and workplace
7、s, roboticists are concerned about the safety implications beyond the factory floor. To address these concerns, leading robot experts have come together to try to find ways to prevent robots from harming people. Inspired by the Pugwash Conferences-an international group of scientists, academics and
8、activists founded in 1957 to campaign for the non-proliferation of nuclear weaponsthe new group of robo-ethicists met earlier this year in Genoa, Italy, and announced their initial findings in March at the European Robotics Symposium in Palermo, Sicily.“Security, safety and sex are the big concerns,
9、“ says Henrik Christensen, chairman of the European Robotics Network at the Swedish Royal Institute of Technology in Stockholm, and one of the organisers of the new robo-ethics group. Should robots that are strong enough or heavy enough to crush people be allowed into homes? Is “system malfunction“
10、a justifiable defence for a robotic fighter plane that contravenes the Geneva Convention and mistakenly fires on innocent civilians? And should robotic sex dolls resembling children be legally allowed?These questions may seem esoteric but in the next few years they will become increasingly relevant,
11、 says Dr. Christensen. According to the United Nations Economic Commission for Europes World Robotics Survey, in 2002 the number of domestic and service robots more than tripled, nearly surpassing their industrial counterparts. By the end of 2003 there were more than 600,000 robot vacuum cleaners an
12、d lawn mowers a figure predicted to rise to more than 4m by the end of next year. Japanese industrial firms are racing to build humanoid robots to act as domestic helpers for the elderly, and South Korea has set a goal that 100% of households should have domestic robots by 2020. In light of all this
13、, it is crucial that we start to think about safety and ethical guidelines now, says Dr. Christensen.DifficultiesSo what exactly is being done to protect us from these mechanical menaces? “Not enough,“ says Blay Whitby, an artificial-intelligence expert at the University of Sussex in England. This i
14、s hardly surprising given that the field of “safety-critical computing“ is barely a decade old, he says. But things are changing, and researchers are increasingly taking an interest in trying to make robots safer.Regulating the behaviour of robots is going to become more difficult in the future, sin
15、ce they will increasingly have self-learning mechanisms built into them, says Gianmarco Veruggio, a roboticist in Italy. As a result, their behaviour will become impossible to predict fully, he says, since they will not be behaving in predefined ways but will learn new behaviour as they go.Then ther
16、e is the question of unpredictable failures. What happens if a robots motors stop working, or it suffers a system failure just as it is performing heart surgery or handing you a cup of hot coffee? You can, of course, build in redundancy by adding backup systems, says Hirochika Inoue, a veteran robot
17、icist at the University of Tokyo who is now an adviser to the Japan Society for the Promotion of Science. But this guarantees nothing, he says. “One hundred percent safety is impossible through technology,“ says Dr. Inoue. This is because ultimately no matter how thorough you are, you cannot anticip
18、ate the unpredictable nature of human behaviour, he says.Legal problemsSo where does this leave Asimovs Three Laws of Robotics? They were a narrative device, and were never actually meant to work in the real world, says Dr. Whitby. Let alone the fact that the laws require the robot to have some form
19、 of human-like intelligence, which robots still lack, the laws themselves dont actually work very well. Indeed, Asimov repeatedly knocked them down in his robot stories, showing time and again how these seemingly watertight roles could produce unintended consequences.In any case, says Dr. Inoue, the
20、 laws really just encapsulate commonsense principles that are already applied to the design of most modem appliances, both domestic and industrial. Every toaster, lawn mower and mobile phone is designed to minimise the risk of causing injury yet people still manage to electrocute themselves, lose fi

At the very least, robots must meet the rigorous safety standards that cover existing products The question is whether new, robot-specific rules are needed- and, if so, what they should say.“Making sure robots are safe will be critica
22、l,“ says Colin Angle of Robot, which has sold over 2m “Roomba“ household-vacuuming robots. But be argues that his firms robots are, in fact, much safer than some popular toys. But what he believes is that robot is just like other home appliances that deserves no special treatment.Robot safety is lik
23、ely to appear in the civil courts as a matter of product liability. “When the first robot carpet-sweeper sucks up a baby, who will be to blame?“ asks John Hallam, a professor at the University of Southern Denmark in Odense. If a robot is autonomous and capable of learning, can its designer be held r
24、esponsible for all its actions? Today the answer to these questions is generally “yes“. But as robots grow in complexity it will become a lot less clear cut, he says.However, the idea that general-purpose robots, capable of learning, will become widespread is wrong, suggests Mr. Angle. It is more li
25、kely, he believes, that robots will be relatively dumb machines designed for particular tasks. Rather than a humanoid robot maid, “it s going to be a heterogeneous swarm of robots that will take care of the house,“ he says.（分数：70.00）(1).This passage is mainly about the benefits of developing robots
