Programmable automatic dispenser

A dispensing apparatus, comprising:

• a rectangular first vertical side member;
• a rectangular vertical back member coupled at a first vertical edge to the first vertical side member such that the vertical back member and the first vertical side member form orthogonal vertical planes;
• a rectangular second vertical side member coupled to a second vertical edge of the vertical back member such that the first vertical side member and the second vertical side member form parallel vertical planes, and such that the first vertical side member, the vertical back member, and the second vertical side member form a vertical structure;
• a plurality of rectangular shelves configured to fit within the vertical structure in a first position such that each shelf in the first position defines a plane perpendicular to each of the first vertical side member, the vertical back member, and the second vertical side member;
• a vertical actuator channel coupled along a vertical edge of the second vertical side member opposite the vertical back member, wherein the actuator channel comprises a plurality of trip rod slots, and wherein each trip rod slot is configured to retain a shelf in the first position;
• and
• a plurality of actuators coupled to the actuator channel, wherein each actuator is separately controllable to release a shelf from the first position to a substantially vertical second position, wherein transitioning from the first position to the second position vertically dispenses any material resting on the shelf.
