DARPA is currently working on two projects which could lead to killer bots. One is Fast Lightweight Autonomy (FLA) which is designing a tiny rotorcraft to manoeuvre unaided at high speed in urban areas and inside buildings. The other and Collaborative Operations in Denied Environment (CODE), is aiming to develop teams of autonomous aerial vehicles carrying out “all steps of a strike mission — find, fix, track, target, engage, assess” in situations in which enemy signal-jamming makes communication with a human commander impossible.
