This week we took a drive to the Home Depot approximately twenty minutes off campus to pick up various supplies. Because we already had PVC piping, we only needed to get PVC fittings and a plastic tarp to begin our prototyping. We bought six right angle PVC fittings and four t-shaped fittings which will be enough to hold together the frame for one backpack. We also bought a 9 ft. by 9 ft. plastic tarp which will be cut up and used to hold in the contents of the villager's loads in their packs.
After retrieving the needed supplies, we began to work on putting the frame of the backpack together. First, we cut most of the PVC piping needed to build the frame. We used PVC cement and primers for stability when connecting pieces of the frame. The frame has not yet been completed but we plan to work on it more during lab and then go from there. This week we plan to complete a prototype of the frame and then use the plastic tarp to get a full prototype model of the backpack done. We will then test our prototype and make improvements based on how well the backpack works.
