Hand crafted autonomous turrets
aren't anything unusual, but rather than piecing together a masterful creation with pre-fab parts, the folks over at Burnt Popcorn
managed to take things one step further. After finding that cheaper AirSoft
guns lacked the accuracy they craved, they decided to "make their own mechanism to fire BBs." The goal of the project was to enter the Defcon Bots competition and craft a machine that could "shoot down all the targets before the other person does." Of course, the actual programming involved in building this eagle-eyed
shooter is a bit more extensive than can be covered here, but if you're looking for a pretty thorough guide complete with video demonstrations, be sure and give the read link a minute of your time.
