i was looking through a popular science magazine the issue that talks about war in space(newest?) anyways it's relatively new. well they had a article about a robot expo. well there was basically this one that was a home unit or soemthing that could actually shoot paintballs in a "self defense" mode. What exactly is the purpose i don't know, doesn't seem that effective of a defense, it's better than bullets, but doesn't sound that good to either
