South Korea just unveiled the first generation of autonomous robots armed with lethal weapons. They'll eventually be deployed to help secure their 155-mile-long border with North Korea, and they come equipped with rubber bullets and machine guns. According to the Associated Press:

The robot also can distinguish people from moving objects such as a vehicles from up to 1.2 miles away in the daytime, and half that distance at night, the ministry said in a news release.

It can identify an enemy up to 30 feet away through a password, the news release said.

It also probably thinks humans taste like "bacon".
