Robots that kill. Robots in Warfare?

Robots are increasingly being used for warlike purposes. While we are very far from building a robot like the one on the movie "The Terminator", fully automated machine guns have already been deployed between North and South Korea. There are active research projects in several counties aimed at bulidng autonomous combat vehicles, and some of there are close to the point at which they can automatically deliver lethal force. Singapore seems to have a funding competition regarding what seems to be an automatic robot assasin.

In this context, Georgia Tech is running a web-based survey on the use of robots capable of delivering lethal force.
