the problem with ONLY ONE EMP to stop Autonomous robots of Air, Land, Sea or Space?

 Here is what I realized about this. You would likely need (for any city or military base) a repeatable EMP generator. 

The first time you used this you would fry all Autonomous robots in the vicinity of that EMP burst.

However, because often the world fights in Asynchronous warfare now, these autonomous robots of air, land, sea or space could come any moment or moments 24 hours a day ongoing.

So, you would need a repeatable EMP whenever enough Autonomous Robots were attacking from Air, land, sea, or space in order to prevent more deaths in your locality whether it was a city or military base.

So, you might need one that could generate an EMP 25 or more times in any battle or war situation.

It would never be troops attacking that were human. It would ALWAYS be Drones and Missiles that were autonomous attacking or robot troops on the ground or from the sea, AIR, or Space.

So, you would have to find a way to fry their electrical circuits.

Also, if they are lithium Ion based rechargeable batteries they likely would catch fire and set other things on fire when you did this like Teslas and other EV cars and trucks often caught fire in Los Angeles and set other cars and trucks and houses on fire too during the Pacific Palisades Fire and the Eaton Fire there.

And since you cannot put out a Lithium Ion rechargeable battery fire for sure within a month or two without it starting up again and setting someone or something else on fire this is going to be a problem two regarding Autonomous robots attacking anywhere on earth without human Troops on the battlefield at all. 

NOTE: However the first EMP would knock out in that area (city or military base) all electronics not militarily designed to survive a nuclear holocaust.

Which means for you and me: Everything including all cell phones, all cars of any kind, all trucks, all computers all electric motors, all gps devices. Nothing electric would likely work ever again just from the first EMP.

So, any area that had even one EMP would literally have to replace anything electric or be literally in the Stone age until they did.
