Experts say that in ten years from now, there will be more robots than soldiers in the U.S. military. Each soldier could have one or five robots flanking him, looking for enemies and doing more.

Scott Hartley, the co-founder of 5D Robotics, demonstrated his companies' machines along with Northrop Grumman, QinetiQ, HDT Robotics and other robotics corporations catering to the US military. He added that "robots can save lives" and help soldiers survive a hostile environment.

The systems that participated in the demo were both autonomous and remote controlled. The robots had to demonstrate their ability to accurately fire the M240 machine gun (pictured below) at targets 800 meters away.
