The point of this exercise was to get us accustomed to designing around existing components. My group was given a blender to redesign. But rather than re-designing the shell, we wanted to attempt something more fun, like an airboat. We ended up purchasing more components like an rc toy car, and the 12V battery. I dealt with the more technical issues whilst my friends took on the overall boat form, and component arrangement.
