Today we met as a group and continued working on the project. We laser cut the base plate, ring, and a cardboard gun. The base plate and ring give the rotating turret something for the wheel that rotates it something to push off of and is essential to its functionality. The cardboard gun replaces the actual airsoft gun. We are trying to get lights to flash simulating firing from the controller but are having trouble with the circuitry. In theory it will work and it sort of does but something is not quite right. We are pretty close to being finished and we don't have much time to spare because the needed parts weren't acquired until very recently. I designed and will 3D print an emblem to attach to the front of the car, and its shown below. As far as fabrication goes this was obviously a prototype so it was not done to an exact science. It was much easier and faster to design and fabricate by hand as well as being way more versatile. Much of the design was done on the computer in solidworks files, but was redesigned or adjusted in the field. The gear ratios were designed to fit the gears that were available (ordered on amazon). Some of the components were made by hand out of cardboard and attached by a combination of nails, tape, and hot glue. It is rudimentary, but functions. If we were to continue on with this project, which I may, we would use the hand crafted parts as inspiration for clean cut computer generated parts. This is exactly how we came to use the base plate and ring pushing against a rotating wheel instead of a gear system for the rotation. Moving forward we will make as many improvements as we can before the expo on Friday(tomorrow in 12 hours).

As shared before here is a link to a fileshare of the solidworks files. http://ge.tt/5TMuul62/v/0?c
