History Fridge / IRobot

* In 'Little Lost Robot', the second test that Calvin comes up with involves dropping a weight towards a human, but with (fake) electrified cables between the robots and the person. However, the robots stay seated, and one of the Nestors points out afterwards that they couldn't save the human and if they stayed seated, they might save a human some time in the future. So, why didn't Calvin arrange a test where the robots would be killed 'after' saving a human? That would have caught out the rogue Nestor, since then a normal robot would be able to save a human (at the cost of its life) and so would do so, but the rogue one wouldn't.

* Sonny's second Positronic brain, the one that lets him override the Three Laws, is built into his chest. Dr. Lanning gave him a heart.

* So why did the robot running with the bag stop when Spooner ordered it to? This would appear to violate the second law, except that the owner's inhaler was in the bag. Stopping as instructed might violate the first law by allowing the robot's owner to come to harm.
* Like Spooner says the building design of [=USR=] is ''"messed up"'', with thin walkways and no hand rails leading to the main console controlling [=VIKI=]'s interface. When you think about it, really, who's going to try and shut off a super-computer suspended far above the ground floor on tiny metal pathways?

* When Spooner is being attacked in his car by the robots who nonsensically insist he's having a car accident? That's not just Viki employing ImplausibleDeniablity. The robots are [[BrainwashedAndCrazy hallucinating that they're saving him]], to get around their first law restrictions. Think about that from their perspective now. It's unpleasant.

** Because "Protect Humans" is one of the Three Laws? As shown with the old models, they can save people's lives by rescuing them with super strength and/or retrieving medicine with super-speed. The Three Laws extend to all humans, not just the owners.

!!!Fridge Horror
* Spooner mentions in his flashback that the robot that saved him calculated that he had a %40 chance of surviving over the girl Sara, but in order to do that he had to ''tear Spooner's arm off.'' He has to live not only with his survivor guilt but the ''conscious memory'' of the pain of having his pinned arm forcibly torn from his body. No wonder he's so grouchy.
** Not so, this troper remember that Spooner mentioning that his arm was crushed by the incoming truck that pushed both the vehicle into the river. He lost it during the surgery or the reconstructive surgery.

!!!Fridge Logic
* At one point Detective Spooner says that he keeps expecting the marines or the army or special forces to show up, Dr. Calvin says that all defense services are heavily supplied by U.S. robotics contracts. at first glance this makes sense because current US policy is moving more and more towards taking soldiers off the front lines in favor of expendable drones, and on top of that the movie has shown that even the civilian line of robots are more than capable of outperforming a human in most combat situations. But if all robots are 3 laws compliant that would make the army robots extremely ineffective soldiers.
** They don't have to be soldiers. Could be drivers, clerks, suppliers, scouts, any number of things which--if they stopped cooperating--would ensure the army simply can't move.
*** You don't need to harm a man to stop him. The books frequently include scenes of robots fast enough to rip guns out of people's hands and hold them down without hurting them.
*** Also, quite a bit of the equipment used by humans in modern militaries is very computerized, especially high-performance equipment like airplanes. It's possible that vehicles or weapons that aren't necessarily ThreeLawsCompliant would simply be shut down remotely by V.I.K.I.
* Why are robots designed to be personal assistants and servants super fast and super strong? They are also designed to ''protect'' humans, and are thus overengineered to be capable of, say, quickly extracting a struggling powerfully built man from a wrecked car.

*** As well as the seemingly gratuitous shower scene early in the film, which serves as a point on second viewing.

** Dr Lanning is shown to have planned his BatmanGambit insanely well... anticipating Spooner and Sonny's actions throughout the story. Given his closeness to Calvin, he no doubt anticipated that when Sonny attempted to run, she'd naturally seal the room. Sonny would then naturally follow in his ''footsteps'' by [[spoiler: throwing himself out of the window and landing exactly where his body did]].
*** Lanning also may have intended this so that [[spoiler: he would land in front of the 3 Laws, symbolising the ''creator's'' wish for the ''death'' of the 3 laws.]] When Sonny would do this [[spoiler: the force of him landing beside the 3 Laws, would send cracks running towards them, symbolising that Sonny, the ''creation'', would ''break'' them.]]

** When Sonny said "I did not murder him", he was telling the truth. The doc ordered him to. ''It was suicide''.

** [[spoiler:When asked about Lanning, Sonny says he "did not murder him!" Lanning ordered him to. It was a ''suicide''.]]
