Remote detonation via signal wire is replacing cell-activated IEDs. You can counter a radio signal, but not a hard wire that is inactive till it is tripped. Think of those old TNT levers that set off some old movie explosion, with the wire coiling away from the bomb. Those lines are buried for kilometers. Someone on a phone calls the person who is going to trip the bomb right as the convoy approaches. It is a really hard problem to counter. The best detection rate will likely be from a vision algorithm that can detect changes in the dirt around some garbage pile used to cover a IED. That kind of vision algorithm is extremely hard to make. Either way, bombs are already automated. Even third world countries make use of the most vicious robot in the world, requiring no recharge, and lasting for decades: land mines.
