You might be able to tell what a turret is from the lesson picture: it's a location where something can be shot with some amount of protection and visibility. Armored tanks have them. Fish tanks usually don't. Your Turret Bot uses the left and right IR sensors to move the turret left or right, and then it uses the center IR sensor to fire rubber bands (not included). Warning: please don't point the Turret Bot at other people!
