What we're studying:
We studied the cereal making process, erector motors, relays, Arduino C, VEX C, digital electronics, servos, and simple mechanics. We also learned how to work as a team and realized how important that is.Our Team Leader's favorite quote:
Learn how to learn.Why we think we should win:
We have learned a lot, like how to work together and keep the steps simple. Our team has put a lot of effort into this machine; we have had people come most weekends to work, and a few students skip lunch every day to work on the machine. Different people work at different times, so we have had to learn how to communicate with each other. Since teamwork, and learning how to work hard, are important aspects of Rube Goldberg we definitely deserve to win.
To celebrate the 30th Anniversary of the Rube Goldberg Machine Contest, General Mills opened up a new Cereal Factory. Everything was going as planned, until Cap'n Crunch's son, Lucky, invaded the factory to look for some food. He stayed hidden throughout the tour, and got to see how the raw materials are brought in and crushed. Lucky learned how to put the break in fast. At the end Lucky got his wish, a bowl of cereal being poured.
