Week 4 Design of Pill Dispenser

Front-Top-Side View

The front view of the pill dispenser has been chamfered on the sides to add more visual appeal to the overall design. For the inside of the design, the pill storage system has changed. The funneling system has been greatly changed. Instead of a board square plane where pills would fall onto, the pills will fall on a triangular plane to funnel into a specific drop off point. On the top, you will see a little cut out. That cut out is to show that you can lift a little knob built into the cutout to lift a hatch to refill the pills.

Back-Top-Side View

Notice the little knob on the left side of the design. That knob will open the back side for maintenance, if needed, of the servos and Arduino.

Week 4

During the fourth week of our Design Project, the team worked on sourcing and gathering all of the materials that we would need for the project. This included cardboard, hinges, servo motors, wiring, and an arduino board. The weekly lab period was used for creating the basic design concept of the device in AutoCAD, and starting the coding for the arduino board. For our first prototype, we plan on constructing the body out of thick cardboard, which will allow us to make quick adjustments and changes without the use of much hardware.

Week 9

During Week 9, we assembled the final parts of the pill dispenser. The motors were placed inside of the motor compartment, and the pill dispensing compartments were created. We plugged in each motor and tested the dropping mechanism using our Arduino code. Each slot was successfully able to dispense the pill capsule onto the ramp below. Included are pictures of our wiring and prototype so far.

Week 10

Week 10 was the final week of our Design Project. During this week, finishing touches were added to the pill dispenser, including optimization of the code, and the locking mechanism as a fail-safe. The group also had a chance to present their project both in class, and at the senior design event, where ten freshman design groups were also allowed to present their project.
