You know how it is -- we're frightened and appalled by the thought of unmanned killing machines, but if they must exist we really, really want to play with one. The US Army's latest nightmarish deathcopter / awesome tech toy is a little something called the Autonomous Rotorcraft Sniper System (ARSS). Essentially a .338-caliber rifle mounted to the bottom of a Vigilante unmanned helicopter (though it could eventually be made to work on a Predator drone, for instance), this bad boy utilizes a modified Xbox 360 game controller for targeting while the vehicle itself stays put courtesy of its autopilot functions. Never again will your favorite sniper need to leave the comfort of his barracks! Airborne testing begins in July, with autonomy to come soon after that and a possible robot apocalypse estimated for Q4 2011.
