This is an UAV which can operate autonomously or being radio-controlled. The UAV will detect explosive devices by scanning the ground for metal and eventually mark them. It should also be able to transport or destroy the device.
In cause of the intuitive operation it can be used in war zones by trained professionals as well as in mined zones in underdeveloped countries to save the lifes of thousands of uninvolved civilians every year. It is this projects intention to make our world a saver place:)
Maybe I'm going to realize this via ZigBee, however I've never worked with wireless transmission systems, although I'm pretty sure it should be easy to use, easy to replace/repair and not too expensive.
