Week 3

During Week 3, our group used the lab period to finish up any brainstorming. These ideas were incorporated into our Design Proposal, as well as our constraints and parts list. Throughout our Design Proposal, we discussed the goal of our device, and what deliverables we hope to achieve.  The proposal was also used as a method of discussing the details behind our project, such as preliminary designs, parts lists, facilities and resources that will be used, and the steps we will be taking in constructing our design. After finishing our Design Proposal, our group also took the time to start ordering and sourcing the parts that would be needed for our design.

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.   Figure 1: Front View Figure 2: Back View

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.
