If you can't beat 'em, join 'em. Or something like that. When South Korea notice a drone, with a camera, hovering near its borders, it decided that it needed to protect itself from such unmanned aerial vehicles or UAVs. And what better way to do that than by using another UAV. Roboticists at the Korean Advanced Institute of Science and Technology or KAIST are trying to develop drones whose sole purposes would be to intercept and disable other drones. It's like Robot Wars, except in the sky and for less entertaining purposes.
