Mainstream sci-fi has conditioned people to think of humanoid robots. Iain M. Banks was writing about concepts like blade drones in the Culture series (basically scalpels on hovering rockets) as far back as the 80's. Terrifying stuff if made real, and they were being used primarily by the 'Good Guys'.

yep the real scary shit is the little micro flying assassin drones. Shit that could be deployed at scale to eliminate targets way more effectively than anything humanoid ever could.

But sci-fi has conditioned us to think of robots being human shaped

I'm still surprised that they haven't made monkey robots, which would just be human robots except you also have a tail that can function as an additional limb. Stick a camera at the end of the tail and the robot now has 360 degree vision of its surroundings.

Mother Courage

Terrain becomes an asset rather than an obstacle, accessibility as a persistent shock assault and breacher unit, can deliver heavier payloads without having to sacrifice itself in single or tandem strikes, can hold territory, not simply pound it from the air

A camouflaged humanoid robot with a heavy grenade launcher mindlessly walking far behind enemy lines can do more damage than ten microdrones
