A new pair of Russian robots has been developed that can track and attack humans from more than four miles away. The devices are designed for use on the Russian border, and claim to accurately detect and attack ground and aerial threats long before they reach Russian soil. Key technology at the robots' disposal include radar, HD and thermal video imaging, and multiple long-range grenade launchers. Weapons experts have also been working on a high-tech explosives system, labelled the'Alpha Device,' to work in tandem with the Flight surveillance robots. The first of the two new robots will act as a pair of scrupulous eyes for Russian border guards.
