They are extremely vulnerable to the same drones humans are.

It's more along the lines of this is a patch were not expecting active fighting this robot can act as a deterrent and surveillance.

Cheaper and simpler than a loitering IRS drone. But more concentrated in domain.

I believe for a while Samsung developed similar drones for the demilitarised zone in Korea. Those could be static as they were hard wired in.

I am not confident about this. Human gets disabled by few small shrapnel projectiles into soft tissue. It is possible to build way more protected robot, for which you need some direct hit to disable it. That robot could also be very agile: e.g. do some evading jump at the last moment before being hit.
