A robot dog design armed with a 6.5 mm Creedmoor sniper rifle capable of precisely hitting targets from 3,940 feet away has been unveiled at the US Army trade show. The'Special Purpose Unmanned Rifle' (SPUR) is the brainchild of Philadelphia-based Ghost Robotics and arms manufacturer SWORD International of Sparks, Nevada. Placed on top of one of Ghost Robotics' existing'quadrupedal unmanned ground vehicle' designs, SPUR can be remotely instructed to load, unload and fire its rifle. The firms have yet to reveal the exact configuration of the weapon, nor how much ammunition the machine is capable of carrying or its reload rate. However, tests have shown that the 6.5mm rounds used in the Creedmoor rifle offer an increase in range over the 7.62x51mm cartridges currently used by US forces. It is also presently unclear how much each robot unit and SPUR attachment will cost to purchase and maintain.
