Personally, I do not consider this book as the best cycle robots. But it has the advantage to lay the foundations of the 3 laws of robotics and how they work. This book remains an indispensable based on different stories more or less interesting, but who bring every time a new stone to this great edifice cycle robots. When you think that Izaak Azimov wrote these stories in the fifties, it remains for me a very great in the vision he might have to have future.
