Canine (K9) units have been indispensable in modern warfare. From Military Police to Special Operations Forces, K9s have been brought to some of the most dangerous missions in the world, and many have been awarded accordingly and given even proper burials when they die in action. Now, the U.S. Marine Corp are looking into working with robotic versions of the military dog than can do tasks that flesh and blood K9s are too valuable or unable to do the task.

Last 16 September, members of DARPA and Boston Dynamics help train U.S. Marines operate a prototype robotic quadruped called "Spot" in Quantico, Virginia. "Spot" is the smaller brother of the more famous "Big Dog" that is also developed by Boston Dynamics (which is owned by Google). Spot is the a 160lb and more agile electrically powered, hydraulically actuated robot that can help the Marines in tight spots.

The U.S. Marine Corps have been testing robotic systems and autonomous vehicles, deploying them in various terrains such as hills, woodland, and urban environment. So far, Spot was able to perform in these terrains as compared to other prototypes, including the "Big Dog."

Controlling Spot requires an operator with a laptop controller that can send commands to Spot from up to 487 metres. As Spot was put into various conditions during the test, its being more quiet and agile makes it useful with the Marines.  Spot was sent to scout ahead where usually live dogs were used, it can peek around corners and even sent inside buildings to search for the bad guys before the Marines can come in, helping eliminate the element of surprise in urban combat where casualties are usually high. It can also be used to carry loads need by Marines in combat.

However, Spot is not meant for operational use. The prototype serves as a an evaluation unit and they are still testing other robotic units. The lessons learned in operating Spot can serve to further development of such types of units that the Marines will be confident enough to use in theatres of operations in the future.
