This danger can be avoided, according to puter science professor Stuart Russell, if we figure out how to turn human values into a programmable code.　　Russell argues that as robots take on more plicated tasks, it’s necessary to translate our morals into AI language.　　For example, if a robot does chores around the house, you wouldn’t want it to put the pet cat in the oven to make dinner for the hungry children.“You would want that robot preloaded with a good set of values,”said Russell.　　Some robots are already programmed with basic human values. For example, mobile robots have been programmed to keep a fortable distance from humans. Obviously there are cultural differences, but if you were talking to another person and they came up close in your personal space, you wouldn’t think that’s the kind of thing a properly broughtup person would do.　　It will be possible to create more sophisticated moral machines, if only we can find a way to set out human values as clear rules.　　Robots could also learn values from drawing patterns from large sets of data on human are dangerous only if programmers are careless.　　The biggest concern with robots going against human values is that human beings fail to so sufficient testing and they’ve produced a system that will break some kind of taboo（禁忌）.　　One simple check would be to program a robot to check the correct course of action with a human when presented with an unusual situation.　　If the robot is unsure whether an animal is suitable for the microwave, it has the opportunity
