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. It has a sophisticated pattern recognition which can detect the difference between humans and trees, and a 5.5mm machine-gun.

Yet another milestone on the path toward robots that hunt, kill, and eat people, and use their flesh to generate electric power.

The future is about as bright as a muzzle flash.
