A super small drone.

The mini drones can see over walls and around corners (credit: U.K. Army)
“A tiny remote-control helicopter is being used for surveillance on the front line to detect enemy threats to British troops.
British troops are using a nano drone just 10cm long and weighing 16 grams on the front line in Afghanistan to provide vital information on the ground, Sky News reports.”
Want one?
As small as physics will allow them to be?
One must wonder how long it will be until they’re used domestically.
So drones today are as small as 10cm - how darn small will they be in 2070?
Won’t be long until these little things are everywhere
