Creating a Vending Machine with Lego Mindstorm :: Robotics

Creating a peddling Machine with Lego MindstormAbstractVending forges have come a great way, since their introduction to human societythousands of years ago. Although the basic concept of a vending automobile has notchanged, modern day technology has importantly enhanced them. Our vending machineis no contrasting. Although our vending machine is not top of the line, it is also not such abad atomic number 53 either. We started step forward with building the five main components of a vendingmachine the dispenser, trough, selection device, and hire reader entirely out ofLEGOs. We decided on a door like dispenser and buttons as a selection device. Thepayment we decided to accept were barcodes. The only component that was actuallygiving us trouble was the dispenser. Our first dispenser design was severely flawed.After coming up with a door like mechanism, the dispenser was easily fixed. Althoughwe did prove our hypothesis to be veracious, there are still many improvements that we could make such as improving the design to make it easier to maintain.QuestionIs it possible to create an functional confect machine with only LEGOs?PurposeTo build a candy machine that is capable of Reading a barcode Detecting if it is a bull or not Sending a signal to the other RCX to accommodate to user to1) Select the candy2) While making sure that the machine remains stationaryBackgroundThe History of Counterfeiting the US CurrencyThe counterfeiting of gold is one of the oldest crimes in history. Therefore 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 in short became expenseless. Not worth aContinental became a popular expression that is still hear today.During the Civil War, one-third to one-half of the currency in circulation wascounterfeit. At that time, approximately 1,600 state banks designed and printedtheir own bills. Each bill carried a different design, making it difficult to detectcounterfeit bills from the 7,000 varieties of real bills.A interior(a) currency was adopted in 1862 to resolve the counterfeiting problem.However, the national currency was soon counterfeited and circulated soextensively that it became necessary to take enforcement measures. Therefore, onJuly 5, 1865, the United States mystical Service was established to suppress thewide-spread counterfeiting of this nations currency.Although the counterfeiting of money was substantially suppressed afterwards theestablishment of the Secret Service, this crime still represents a potential endangermentto the Nations economy.
