I'm not sure I'd consider a trap an "autonomous weapon". The trap cannot select a target. It will go off for anyone unlucky enough to step in its trigger.

An autonomous drone will select a target and pull the trigger. It fills in the position of a human pulling a trigger, which is a decision.

Maybe if robots began deciding where to lay mines, i could hand it to you.

I mean by some measure a trap can be worse, as many people have died from mines years after no conflict.
