Perfect for lovers of spy gadgetry and everything robotic comes the remote-controlled, all-weather GroundBot system by Swedish firm Rotundus.
The GroundBot is a spherical surveillance system comprised of polycarbonate with knobby treading, which allows it to traverse snow, mud, and sand. The GroundBot is outfitted with two cameras that project a 3D image onto a screen that enables operators to view and gather information based on the images collected.
Of course, a versatile surveillance system that can withstand various terrains could prove useful in a mixture of situations, which is exactly why the GroundBot is currently being tested by Swedish Defense Forces for airport surveillance – no word yet on whether the tire-sized spheres are indeed inconspicuous enough.
