An artificial intelligence or robot risks its own harm or destruction in order to save a human.
The Benevolent A.I. and the Robot Buddy can be powerful assets to their human masters. Aside from their respective intelligence and ability to do almost anything, these mechanical allies are famously durable. A machine can't feel pain, so a robot can't be hurt. It can't be injured, only damaged, and can surely be repaired. Since it is not technically alive it can never be killed and, even if it is completely destroyed, surely its data is backed up and it can be rebuilt good-as-new. But what if this isn't the case? What if a robot can do more than dream: what if it can feel pain and fear death? There's a chance it will disregard these dangers and perform what is widely-touted as a uniquely-human act: self-sacrifice. Death may come to a machine when it is destroyed with No Plans, No Prototype, No Backup, but sacrifice may take other forms: an artificial intelligence may suffer a partial Mind Wipe, a robot may sustain irreparable damage, an Android may be sufficiently-complex to perceive pain. In any case, it puts itself in harm's way to protect a human. In order to fit this trope, the robot in question must be created by humans and subservient to humans. It must also protect its human master voluntarily: In other words, this machine has the capacity to Turn Against Its Masters but has emphatically decided to do the opposite. For this reason, robots that are Three-Laws Compliant generally don't qualify: they are bound to protect humans compulsively - no willpower needed. Sub-Trope of Heroic Sacrifice. Compare Androids Are People, Too. See also Morality Chip, which may inspire this deed. This is a Death Trope so expect unmarked spoilers in examples.
