Automated Sentry Robots

I've wanted to build one of these things for years. However my goals were a little higher. Complete motion tracking camera/servo system, and it would have fired paintballs or airsoft BBs... Too bad I never thought of the downgrade to common toy as a great selling point. Guess I'm and engineer and not a businessman.
