Week 7: Overview

During week 7, the group downsized the SeaPerch in every dimension. The purpose of downsizing the SeaPerch was to make it lighter and have a smaller surface area. With less surface area, the SeaPerch will not break as much water as it travels, allowing for less drag and faster movement. The group has come to the decision that copper wire will be used to construct two cylindrical structures that will be attached to the front and the back of the SeaPerch. This will funnel water through the SeaPerch, allowing it to move at a faster rate. The copper structures will be attached to two swim caps that will surround the entire SeaPerch, enclosing all materials inside. When considering the material options for enclosing the SeaPerch, the group fund that latex is the best material because it is water proof, water repellent, and inexpensive. Swim caps are made of 100% latex, and their shape is ideal for covering the SeaPerch. By enclosing the SeaPerch, there will be less friction ultimately causing less drag. These features will be added by the end of next week, in order to test the new design.
