阿西莫夫机器人三大定律 Isaac Asimov's "Three Laws of Robotics"
第一定律：A robot may not injure a human being or,through inaction,allow a human being to come to harm.
机器人不得伤害人类,或看到人类受到伤害而袖手旁观
第二定律：A robot must obey orders given it by human beings except where such orders would conflict with the First Law.
在不违反第一定律的前提下,机器人必须绝对服从人类给与的任何命令
第三定律：A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
在不违反第一定律和第二定律的前提下,让机器人做可能危害到他生命.而又它自身又无法.
疑问一：
介于第一个定律疑问：如果是两个人类发生争执?
介于第二定律的疑问：如果人类给出不道德的命令?
介于第三定律的疑问：如果人类给出一个在不违反第一第二定律的前提下
