honeybees are hard to beat when it comes to detecting minute airborne substances, so why not equip them with wireless devices, train them to sniff out explosives and use them to detect land mines, bomb factories and suicide bombers?
For people who create robots, demining is a good assignment. It is not so difficult but also it is no so easy. So now there are many labs which is creating demining robots. I feel that landmine problem will be completely solved in ten years.
