Called the Special Purpose Unmanned Rifle, or SPUR, the system is the creation of robot maker Ghost Robotics and gun manufacturer Sword International.
What you're looking at is actually a 6.5mm Creedmoor rifle from Sword attached to one of Ghost Robotics' quadrupedal unmanned ground vehicles (Q-UGVs). The SPUR was presented at the Association of the U.S. Army's Annual Meeting as the "latest lethality innovation."
The Ghost Robotics' Q-UGVs have already been used before in limited military applications by the U.S. Air Force.
Last year, U.S. Air Force's 325th Security Forces Squadron at Tyndall Air Force Base in Florida tested the robo-dogs in patrolling operations.
