第一条：机器人不得伤害人类，或看到人类受到伤害而袖手旁观。

第二条：机器人必须服从人类的命令，除非这条命令与第一条相矛盾。

第三条：机器人必须保护自己，除非这种保护与以上两条相矛盾。

也有叫三定律的

Law Ⅰ: A ROBOT MAY NOT INJURE A HUMAN BEING OR, THROUGH INACTION, ALLOW A HUMAN BEING TO COME TO HARM.

第一定律：机器人不得伤害人类个体，或者目睹人类个体将遭受危险而袖手不管。

Law Ⅱ: A ROBOT MUST OBEY ORDERS GIVEN IT BY HUMAN BEINGS EXCEPT WHERE SUCH ORDERS WOULD CONFLICT WITH THE FIRST LAW.

第二定律：机器人必须服从人给予它的命令，当该命令与第一定律冲突时例外。

Law Ⅲ: A ROBOT MUST PROTECT ITS OWN EXISTENCE AS LONG AS SUCH PROTECTION DOES NOT CONFLICT WITH THE FIRST OR SECOND LAW.

第三定律：机器人在不违反第一、第二定律的情况下要尽可能保护自己的生存。
