Creating a Vending Machine with Lego Mindstorm :: Robotics

Creating a hawk Machine with Lego MindstormAbstractVending mechanisms have come a long way, since their introduction to human unionthousands of years ago. Although the basic concept of a vending machine has nonchanged, modern day technology has significantly enhanced them. Our vending machineis no different. Although our vending machine is not top of the line, it is also not such abad one either. We started out with building the flipper main components of a vendingmachine the dispenser, trough, selection device, and payment indorser entirely out ofLEGOs. We decided on a door wish well dispenser and buttons as a selection device. Thepayment we decided to accept were barcodes. The yet component that was actuallygiving us trouble was the dispenser. Our first dispenser see was severely flawed.After coming up with a door the like mechanism, the dispenser was easily fixed. Althoughwe did prove our hypothesis to be correct, there are gloss over many improvements that wecould gra nt such as improving the design to make it easier to maintain.QuestionIs it possible to create an operational sugarcoat machine with moreover LEGOs?PurposeTo build a candy machine that is capable of nurture a barcode Detecting if it is a fake or not direct a signal to the other RCX to allow to mappingr to1) Select the candy2) While making sure that the machine remains stationary background knowledgeThe biography of Counterfeiting the US CurrencyThe counterfeiting of money is one of the oldest evils in history. and so Ineeded to find out the ways I could use a LEGO RCX to recognize a correct billand reject it if it is fake.The HistoryDuring the American Revolution, the British counterfeited U.S. currency in suchlarge amounts that the Continental currency soon became worthless. Not worth aContinental became a popular expression that is still heard today.During the Civil War, one-third to one-half of the currency in circulation wascounterfeit. At that time, approximately 1,6 00 state banks designed and printedtheir consume bills. Each bill carried a different design, making it difficult to divulgecounterfeit bills from the 7,000 varieties of real bills.A national currency was adopted in 1862 to resolve the counterfeiting problem.However, the national currency was soon counterfeited and circulated soextensively that it became undeniable to take enforcement measures. Therefore, onJuly 5, 1865, the United States Secret Service was established to conquer thewide-spread counterfeiting of this nations currency.Although the counterfeiting of money was substantially suppressed after theestablishment of the Secret Service, this crime still represents a potential dangerto the Nations economy.
