Robots to the aid of soldiers

Throwable robots act as smart grenades

I know, it’s a sinister topic, but this is just hinting at what will come in the near term future.

I imagine autonomous robots that can perform surveillance on their own based on set areas to cover.

They would be so inexpensive (think the future technology (and cost) of a smartphone with locomotion and digital cognition) that “fatalities” on their part wouldn’t matter.
