Samsung's Techwin division will shortly begin selling heavily armed robot sentries that can identify and shoot a target automatically from over two miles away.
The Intelligent Surveillance and Guard Robot was jointly developed with a South Korean university, and is designed to replace some of the troops guarding the border with North Korea.
The robot will be available next year at a cost of $200,000 per unit, and the company expects to sell 1,000 in the first year.
The system uses twin optical and infrared sensors to identify targets from 2.5 miles in daylight and around half that distance at night. It has a microphone and speakers so that passwords can be exchanged with human troops.
If the password is not accepted the robot can either sound an alarm or fire at the target using rubber bullets or a swivel-mounted K-3 machine gun.
Completely froolpoof. Korea is also working on eight-legged combat robots (version pictured here) and apparently already has little robot armored cars with guns on top (this via Selectroclash?). More video below:
