Goal: Simulate a drink vending machines that will serve the users at least 3 different drinks. Requirements: Max of 2 students per group The user will push a button to hear a simple set of instruction being played through a tape recorder or computer's speaker. The instructions will tell user how each switch corresponds to a different type of drink. For example: "For Coffee, press button no. 1, for Coke press button no. 2, ellipses" The vending machine should not get activated if it's running out of supplies. For example, if there is no Coke available, then pressing the 'coke button' should not do anything. There should be an emergency button that when pressed will halt all activity and safely return the robot to its home position regardless of current position of the robot. Serving the drink means, grabbing it from the stock position and pouring it inside a cup. Users will have access to two different type of cups. These cups vary in their diameter size. Before each serving the robot should measure the diameter of the cup that's sitting in the "pouring spot. If the cup is the small sized cup, the robot should pour the drink for only 2 seconds. Otherwise if the cup is the bigger one, then it should pour it for 3.5 seconds. During the pouring operation, either a beeping sound or a flashing light should get activated to indicate that pouring is in progress. Should be done using scorbase robotic software (the tape recoder is not needed)
