In July 2002, the US Army Robotics Study Team tested man-portable robots and controllers in combat for the first time. These robots quickly explored caves, bunkers, and other objectives in Afghanistan via remote control while the soldiers remained in secure positions. These systems, developed in less than a month, are still in use a year later. The M7 systems are based on equipment first prototyped for the Land Warrior program and clearly demonstrate that helmet-mounted display technology has reached a deployable state of the art for the infantry soldier. Further work on human factors and ergonomics are the new focus of development for this type of equipment.
