This astounding industrial accident would not have happened in a world in which robot behavior. 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 Hollywood film. But decades later the laws, designed to prevent robots from harming people either through action or inaction, remain in the realm of fiction.
With robots now poised to emerge from their industrial cages and to move into homes and workplaces, 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. "Security, safety and sex are the big concerns," 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 roboethics group. Should robots that are strong enough or heavy enough to crush people be allowed into homes？ 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, says Dr. Christensen. According to the United Nations Economic Commission for Europe's World Robotics Survey, in 2002 the number of domestic and service robots more than tripled, nearly outstripping their industrial counterparts. 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, it is crucial that we start to think about safety and ethical guidelines now, says Dr. Christensen.
So 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 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 to try to program them to avoid contact 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.
Regulating the behavior. of robots is going to become more difficult in the future, since they will increasingly have self-learning mechanisms built into them, says Gianmarco Veruggio, a roboticist at the Institute of Intelligent Systems for Automation in Genoa, Italy. As a result, their behavior. will become impossible to predict fully, he says, since they will not be behaving in predefined ways but will learn new behavior. as they go.

Robot safety: as robots move into homes and offices, ensuring that they do not injure people will be vital. But how？
The incident
In 1981 Kenji Urada, a 37-year-old Japanese factory worker, climbed over a safety fence at a Kawasaki plant to carry out some maintenance work on a robot. In his haste, he failed to switch the robot off properly. Unable to sense him, the robot's 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 gruesome 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 decades 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 the 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.

With robots now poised to emerge from their industrial cages and to move into homes and workplaces, 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 activists founded in 1957 to campaign for the non-proliferation of nuclear weapons—the 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," 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" 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, says Dr. Christensen. According to the United Nations Economic Commission for Europe's 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 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 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 and ethical guidelines now, says Dr. Christensen.
