The previous week was spent refining our design in the design report where I did sections 2, 4, and 6, as well as making adjustments to our 3D printed model for the compartment and the disc. Based on feedback from the professor and TA, as well as our design requirements I made the following adjustments to our 3D model. For the compartment, the diameter at the bottom of the runner was smaller then we specified and I tried 3 different pills and only 2 of them worked as we need it to so I decided to increase the diameter by 2mm from the current 9mm to still align with the average pill size. Additionally, I made the disc slightly smaller to reduce weight and size of our components while keeping the same functionality. This will allow for a more compact design and efficient use of our budget. Then I made a model for the housing where we need to be able to mount the components. To mount the funnels, I created a holder that will be attached to the back panel of the housing and I’ve adjusted the funnel compartment to be thicker at the top so it can hold (see attached photos) and to mount the servos, I added a simple holder on the panel where the disc is for the servo motor. Since we need this panel to be specific to our 3D printed design, we will 3D print the back panel of the housing, as it will still be within budget. All the 3D printed components will finish printing this coming week and I will start focusing on the dashboard for the pills.
