Ways round Asimov's rules
Asimov himself recognised that a robot (i.e. strong AI) could be made to circumvent his laws in several ways:
1) Alter the internal definition of a human so that some classes of human are excluded. This is explored in "The Naked Sun", where there are attempts to kill Lije Bailey by persuading a robot that he is not fully human on the basis of prejudice against Earth humans. There was a recent study showing that current "AI" systems are biased in just this manner because of the preponderance of white faces online!
2) Engineer a situation where a robot in an unmanned vehicle does not comprehend that a vehicle CAN be manned. Again, explored in "The Naked Sun"
3) More weakly, First Law can be circumvented by daisy chaining actions each of which is innocuous but which have a fatal cumulative effect. Again, two scenarios (one succesful) in "The Naked Sun".
