Re: I would have done a full rant, but why waste the effort.
"You'd have to work out a mechanism for it to drop the grenade and pull the pin."
There are off-the-shelf mechanisms that could drop a grenade. That's a solved problem. As for the pin, you'd pull that before attaching it to the drone. The timer doesn't start when you pull the pin, it starts when you release the "spoon".
All that said, drones carrying grenades seems like a silly thing to be worried about, all things considered.
