using rats to find mines are being done for a long time.
but putting this on a drone? how can they detect it?
drones are flying in sky, should they have metal detector? they will just detect itself.
and how a drone can detonate it?
I don't mean it that way. Someone asked on the cost of using Drones in tracing and detonating landmines, the rat article is a comparable to the idea of using the drones in this way. I do believe that using Rats is cheaper than the Drones.
Based on your shared article, I will just quote some part from it.
When the trained rats find a landmine, they stop and scratch at the TNT-scented spot, which the human de-miners mark and come back later to excavate. If they find a mine, they detonate it on site.
According to the article, they are just
landmine-sniffing rats. They don't detonate landmines.
Human de-miners do the marking and excavation as well as detonation of the landmines. In conclusion, human life is still in danger.
