For months, Russia has been revealing a stable of autonomous weapons—drones, remote controlled tanks, and killer robots—but none have quite captured the world's attention like their latest poster bot—a humanoid machine that Moscow claims will replace mortal soldiers.

You shouldn't worry about the device that Russia is calling "Iron Man" and "Ivan the Terminator"—the federation's military robotics programs is years and billions of dollars behind the United States. Iron Man doesn't stand a chance against DARPA's finest, but there is still reason to fear Russia's future robot mercenaries.

Russia's proto-robo-solider has only been shown in driving simulation with the aid of a remote control suit, but it could someday march into risky areas threatened by explosives, fire, and radiation, according to the Russian paper Komsomolskaya Pravda. The rest of Russia's robotic lineup is much more useful and much less like Isaac Asimov characters. For instance, the Uran-6 is a remote controlled land mine detonator and the Uran-14 is a tank that puts out fires with a scorpion-tail-like water blaster.
