Samsung has partnered with Korea university and developed the machine-gun equipped robotic sentry. It is equipped with two cameras with zooming capabilities one for day time and one for infrared night vision, and can shoot on target with 100% accuracy within 2km (1km at night). It has a sophisticated pattern recognition which can detect the difference between humans and trees, and a 5.5mm machine-gun. The robot also has a speaker to warn the intruder to surrender or get a perfect headshot. The South Korean government is expected to buy 1,000 of these robots by 2007 at the cost of $200,000 apiece and will deploy them along its northern border, coastal regions and military airfields.
ED-209 comes to mind.
