Week 5 Update

Before, the group had only one arm to play the xylophone. Our final prototype would have two, and so the coding was changed and two more motors were added. The xylophone that was bought before had only one mallet in the package. Another mallet could've been made out of wood, however, it was easier to just buy a pair that was exactly the same (for aesthetics reasons, as well). See below for the link. The breadboard was updated to a much smaller size. It used to be the approximately the size of a smart phone, and now it is smaller than a credit card. The new breadboard was not bought, but was in possession of the coder of the group. The coder also had an Arduino kit of his own, so most of the electrical parts are from him. To see if the new breadboard is compatible, a multimeter test was done. Last week, the cat puppet as the project's body was bought, and now it was delivered. A few things was changed because of this approach. The coordinated movement now involves the tail to move, and arms to play the song, and possibly the head looking down when it plays. The eye movement will no longer be needed. A skeleton must be placed inside the cat puppet to hold the puppet upright and hold all the parts in place. This task is expected to be the hardest mechanical task of this project. K'Nex was rented from Drexel resources to see if it can be used. Other ideas included 3D printing the skeleton or making it out of popsicles. During this week, the group was also assigned with making a presentation of what was completed so far (the link to it below).
