To address these conc

28、erns, 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 activists founded in 1957 to campaign for the non-proliferation of nuclear weapons the new group of robo-e

29、thicists met earlier this year in Genoa, Italy, and announced their initial findings in March at the European Robotics Symposium in Palermo, Sicily. B“Security and safety are the big concerns,“ says Henrik Christensen, chairman of the European Robotics Network at the Swedish Royal Institute of Techn

30、ology in Stockholm. Should robots that are strong e-nough or heavy enough to crush people be allowed into homes? Is “system malfunction“ a justifiable defence for a robotic fighter plane that contravenes(违反 )the Geneva Convention and mistakenly fires on innocent civilians? C“These questions may seem

31、 hard to understand but in the next few years they will become increasingly relevant,“ 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

32、counterparts. By the end of 2003 there were more than 600,000 robot vacuum cleaners and 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

33、goal that 100% of households should have domestic robots by 2020. In light of all this, it is crucial that we start to think about safety guidelines now, says Dr. Christensen. Stop right there DSo what exactly is being done to protect us from these mechanical menaces? “Not enough,“ says Blay Whitby.

34、 This is 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. One approach, which sounds simple enough, is try to program them to avoid conta

35、ct with people altogether. But this is much harder than it sounds. Getting a robot to navigate across a cluttered room is difficult enough without having to take into account what its various limbs or appendages might bump into along the way. E“Regulating the behaviour of robots is going to become m

36、ore difficult in the future, since they will increasingly have self-learning mechanisms built into them,“ says Gianmarco Veruggio. “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

37、 go.“ FThen there 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.

38、 But this guarantees nothing, he says. “One hundred per cent safety is impossible through technology,“ says Dr. Inoue. This is because ultimately no matter how thorough you are, you cannot anticipate the unpredictable nature of human behaviour, he says. Or to put it another way, no matter how sophis

39、ticated your robot is at avoiding people, people might not always manage to avoid it, and could end up tripping over it and falling down the stairs. Legal problems GIn any case, says Dr. Inoue, the laws really just summarize commonsense principles that are already applied to the design of most moder

40、n appliances, both domestic and industrial. Every toaster, lawn mower and mobile phone is designed to minimize the risk of causing injury yet people still manage to electrocute(电死 )themselves, lose fingers or fall out of windows in an effort to get a better signal. At the very least, robots must mee

41、t 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. H“Making sure robots are safe will be critical,“ says Colin Angle of iRobot, which has sold over 2m “Roomba“ household-vacuuming robots. But he

42、 argues that his firms robots are, in fact, much safer than some popular toys. “A radio-controlled car controlled by a six-year old is far more dangerous than a Roomba,“ he says. If you tread on a Roomba, it will not cause you to slip over; instead, a rubber pad on its base grips the floor and preve

43、nts it from moving. “Existing regulations will address much of the challenge,“ says Mr. Angle. “Im not yet convinced that robots are sufficiently different that they deserve special treatment.“ IRobot safety is likely to surface in the civil courts as a matter of product liability. “When the first r

44、obot 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 responsible for all its actions? Today the answer to these questions is generally “yes

45、“. But as robots grow in complexity it will become a lot less clear cut, he says. J“Right now, no insurance company is prepared to insure robots,“ says Dr. Inoue. But that will have to change, he says. Last month, Japans Ministry of Trade and Industry announced a set of safety guidelines for home an

46、d office robots. They will be required to have sensors to help them avoid collisions with humans; to be made from soft and light materials to minimize harm if a collision does occur, and to have an emergency shut-off button. This was largely prompted by a big robot exhibition held last summer, which

47、 made the authorities realize that there are safety implications when thousands of people are not just looking at robots, but mingling with them, says Dr. Inoue. KHowever, the idea that general-purpose robots, capable of learning, will become widespread is wrong, suggests Mr. Angle. It is more likel

48、y, he believes, that robots will be relatively dumb machines designed for particular tasks. Rather than a humanoid robot maid, “its going to be a heterogeneous(不同种类的 )swarm of robots that will take care of the house,“ he says. 47 It is pointed out there is no absolute safety through technology due t

49、o the unpredictable nature of human behavior. 48 It sounds easier said than done to program robots to avoid contact with people. 49 According to a survey, the number of domestic and service robots was three times over that of industrial robots in 2002. 50 To deal with the rising safety concern about domestic robots, robo-ethicists held meetings in Genoa. 51 To a great extent, a robot exhibition contributed to the issue
