"Samsung has partnered with a Korean university to develop a robotic sentry equipped with a 5.5mm machine gun. Meant for deployment along the DMZ between North and South Korea the $200,000 robot employs sophisticated pattern recognition software for targeting humans. No three laws here, but the robot does include a speaker that can be used to politely issue a warning before taking the target out. The promotional video is both scary and funny at the same time."
