Everyone afraid of this, you ought to be afraid of micro-drones like the Black Hornet Nano - https://en.wikipedia.org/wiki/Black_Hornet_Nano
No one is going to send a fleet of these ultra-expensive Robo-Killers to assassinate you and everyone else on the battlefield. Once these micro-drones can be mass produced cheaply enough, and you can put enough high-explosive on them to fly up to a person's neck and !!pop!! someone's head clean off, you'll see them programmed with swarm behavior and be unleashed onto the battlefield.
They fly faster than you can run (13 miles per hour), have a 1 mile range, and a 25 minute flight time. More than enough capability to swarm entire battalions and wipe them out.

And can be trivially defeated by some netting, blinded by bright lights/lasers, and/or knocked out of the sky by leaf blowers and umbrellas. Despite what certain propagandaesque sci-fi "warning" videos would have people believe, I'm least worried about these nano-drones. At the end of the day bullets are still cheaper, less complicated, and more effective. And as soon as you give the drones some standoff capabilities to mitigate some of the countermeasures, you start loosing many of the perceived "benefits" and are back to just using guys with guns.
If an enemy force has already made up its mind to kill, I don't see this making it any easier/more reliable/more effective than well-established alternatives.
This looks like us so it’s easier to see how we’re threatened by it. It’s more visceral. My cats don’t care about my vacuum but if it walked and jumped their neutrons might fire differently.
