The invention in one embodiment includes an aiming device coupled to an actuator and an object. The system comprises a base attached to the actuator, and a frame rotatably affixed to the base and the object. The frame and object rotate together about a first axis in response to activation of the actuator, while the object discretely rotates relative to the frame about a second axis different than the first axis each time the frame rotates a predetermined angle relative to the base.
