American soldiers may soon be joined on the battlefield by machine gun-toting robots on wheels, according to U.S. Army officials.

Earlier this month, military leaders attended a technology demonstration at Fort Benning, Ga., where robotics companies exhibited their most advanced weaponized creations, reported ComputerWorld.com. The display was designed to show the potential ways robots could support troops in combat.

"We were hoping to see how they remotely control lethal weapons," Lt. Col. Willie Smith, chief of unmanned ground vehicles at Fort Benning, told ComputerWorld of the technology demonstration. "We were pleased with what we saw here. The technology is getting to be where it needs to be. It's a start."

While gun-toting robots are not yet officially used by the military in combat, the U.S. Army and the U.S. Marines have experimented with prototype machines.

Smith said he is unsure how soon armed robots may join the Army's ranks, but he hopes the military will begin introducing these types of robots into battlefield settings within five years. "They're not just tools, but members of the squad. That's the goal," Smith told ComputerWorld.

Northrop Grumman, iRobot Corp, HDT Robotics and QinetiQ were among the commercial companies demonstrating their hardware for the military, reported ComputerWorld. The robots can be equipped with a variety of weapons, and are capable of performing a range of tasks.

Northrop Grumman's robot, the Carry-all Mechanized Equipment Landrover or CaMEL, uses a telescope and thermal-imaging technology to identify enemies up to 2 miles (3.5 kilometers) away. The robot can operate for more than 20 hours on 3.5 gallons of fuel, according to Northrop Grumman. The CaMEL is also capable of wielding a number of lethal weapons, including a grenade launcher, an automatic weapon and anti-tank missiles.

The robots, which can be operated through satellite communications, ensure that human soldiers can remain safely out of harms way, in some cases hundreds of miles away from the battlefield.

Executives from the robotics companies say the robots can be air-dropped into a war zone from a helicopter or plane, or may rove alongside the troops on patrol, reported ComputerWorld.

Still, don't expect these mechanized warriors to take over completely for human soldiers. At least not yet, said Tollie Strode Jr., a senior project officer with the Maneuver Battle Lab at Fort Benning.

"The robot may acquire an enemy target, but it will still always ask a human for permission to fire," Strode told ComputerWorld. "I think the ability for a robot to acquire and assess a target and ID it as a threat and fire is probably five or 10 years out. However, even if that capability exists … we'll have a human in the process of deciding what to do."
