Today, DA is absent from class; therefore we cannot go down to the lab. Instead, we will work on thinking about what is still left to do. My partner and I still have three major things to do: propellers, floatation, and water proofing.
For propellers, my partner and I need to make another trip to Hobby Masters. By now, they should have received the shipment of the larger propellers. We need to attatch the propellers to the designated drive shafts.
For floataion, we have already aquired very buoyant foam that will be able to easily support our VEX kit. It has 55pounds of buoyant force, and our entire kit weighs 5 pounds. The foam needs to be attatched to the kit by VEX screws. It will extend past the claw on the forward part of the kit and two inches on either side. This is done in order that the VEX robot may ensure stability.
For waterproofing, we need to do some tests, and we have two different ideas. For the PIC microcontroller, we can wrap it in shrink plastic wrap and use a hair drier to shrink the plastic and create a water proof seal. We can test this by wrapping a piece of paper in the plastic wrap and submerging it in water. If it is dry, it worked. If it is wet, the it did not work. For motors, balloons will be put around and super glued together. This will have the same test as the plastic shrink wrap.
