Today we made a more advanced prototypes including using laser cutters and other tools. We made a 3 ring design that will be strong and durable. We made our design in Rhino and then laser cut it. We made then another prototype that would be stronger because it is out of foam. We then started to use a program called arduino and made a ultrasound distance sensor work. We used a mini arduino so it could fit in our small snitch design and in our final design we will be using about 7 total sensors including ultrasonic distance and IR sensors. We have improved our thoughts about the inside of the snitch and what it will look like. Today we also put up a post on our presidents and they were the Harry Potter snitch, a flying orb, and a flying sphere. Our idea is running smoothly and we will be able to start our final design soon.
