The three laws of Robotics:
1) A robot may not injure a human being or, through inaction, allow a human being to come to harm
2) A robot must obey orders givein to it by human beings except where such orders would conflict with the First Law.
3) A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
With this, Asimov changed our perception of robots forever when he formulated the laws governing their behavior. In I, Robot, Asimov chronicles the development of the robot through a series of interlinked stories: from its primitive origins in the present to its ultimate perfection in the not-so-distant future--a future in which humanity itself may be rendered obsolete.
Here are stories of robots gone mad, of mind-read robots, and robots with a sense of humor. Of robot politicians, and robots who secretly run the world--all told with the dramatic blend of science fact & science fiction that became Asmiov's trademark.

A millennium into the future two advancements have altered the course of human history:the colonization of the galaxy and the creation of the positronic brain.Isaac Asimov's Robot novels chronicle the unlikely partnership between a New York City detective and a humanoid robot who must learn to work together.Like most people left behind on an over-populated Earth, New York City police detective Elijah Baley had little love for either the arrogant Spacers or their robotic companions.But when a prominent Spacer is murdered under mysterious circumstances, Baley is ordered to the Outer Worlds to help track down the killer.The relationship between Life and his Spacer superiors, who distrusted all Earthmen, was strained from the start.Then he learned that they had assigned him a partner:R. Daneel Olivaw.Worst of all was that the "R" stood for robot--and his positronic partner was made in the image and likeness of the murder victim!

High above the planet Florinia, the Squires of Sark live in unimaginable wealth and comfort. Down in the eternal spring of the planet, however, the native Florinians labor ceaselessly to produce the precious kyrt that brings prosperity to their Sarkite masters. Rebellion is unthinkable and impossible. Not only do the Florinians no longer have a concept of freedom, any disruption of the vital kyrt trade would cause other planets to rise in protest, ultimately destabilizing trade and resulting in a galactic war. So the Trantorian Empire, whose grand plan is to unite all humanity in peace, prosperity, and freedom, has stood aside and allowed the oppression to continue. Living among the workers of Florinia, Rik is a man without a memory or a past. He has been abducted and brainwashed. Barely able to speak or care for himself when he was found, Rik is widely regarded as a simpleton by the worker community where he lives. But as his memories begin to return, Rik finds himself driven by a cryptic message he is determined to deliver: Everyone on Florinia is doomed . . . the Currents of Space are bringing destruction. But if the planet is evacuated, the power of Sark will end--so some would finish the job and would kill the messenger. The fate of the Galaxy hangs in the balance.

The fifth novel in Asimov's popular Foundation series opens with second thoughts. Councilman Golan Trevize is wondering if he was right to choose a collective mind as the best possible future for humanity over the anarchy of contentious individuals, nations and planets. To test his conclusion, he decides he must know the past and goes in search of legendary Earth, all references to which have been erased from galactic libraries. The societies encountered along the way become arguing points in a book-long colloquy about man's fate, conducted by Trevize and traveling companion Bliss, who is part of the first world/mind, Gaia.

For twelve thousand years the Galactic Empire has ruled supreme. Now it is dying. But only Hari Seldon, creator of the revolutionary science of psychohistory, can see into the future -- to a dark age of ignorance, barbarism, and warfare that will last thirty thousand years. To preserve knowledge and save mankind, Seldon gathers the best minds in the Empire -- both scientists and scholars -- and brings them to a bleak planet at the edge of the Galaxy to serve as a beacon of hope for a future generations. He calls his sanctuary the Foundation.
But soon the fledgling Foundation finds itself at the mercy of corrupt warlords rising in the wake of the receding Empire. Mankind's last best hope is faced with an agonizing choice: submit to the barbarians and be overrun -- or fight them and be destroyed.

故事背景设定在未来，那时的人们被一个叫做“永恒”（Eternity）的组织所统治，“永恒”的成员可以操控时间，他们能通过时间旅行改变历史、阻止灾难的发生，抑或是抹去不想要的东西。其中有一个时间警察违反了“永恒”重要规定，爱上了来自另一个时间的女人，故事也就由此展开。
