bbc: A killer robot is a fully autonomous weapon that can select and engage targets without any human intervention. They do not currently exist but advances in technology are bringing them closer to reality.

Those in favour of killer robots believe the current laws of war may be sufficient to address any problems that might emerge if they are ever deployed, arguing that a moratorium, not an outright ban, should be called if this is not the case.

However, those who oppose their use believe they are a threat to humanity and any autonomous “kill functions” should be banned.
