PIN Ball Game


Pinball is a type of arcade game, in which points are scored by a player manipulating one or more steel balls on a play field inside a glass-covered cabinet called a pinball table (or “pinball machine”). The primary objective of the game is to score as many points as possible. Many modern pinball machines include a story line where the player must complete certain objectives in a certain fashion to complete the story, usually earning high scores for different methods of completing the game. A drain is situated at the bottom of the play field, partially protected by player-controlled metal bats called flippers. A game ends after all the balls fall into the drain a certain number of times. The goal of our project was to design, construct and implement a pinball state machine by using mechanical techniques. The initial stages of the construction process consisted of sketching a design for the deck (playing surface). This process involved several iterations. Once a design was settled upon, it was time to begin the physical construction of the machine. One of the initial concerns was the flipper mechanism. It was unclear how we could effectively translate the lateral motion of a pushed button embedded on the side of the machine into rotational motion smoothly enough to operate a flipper without significant losses to friction. A prototype was constructed to test one of the better theories that we came up with. We knew that the rough dimensions of the deck would be two feet wide and three feet long. We had not yet settled on the pitch of the deck, assuming that this would be best decided by the power that we could get out of the flippers, as they needed to be able to propel the ball close to three feet uphill, and then up an even steeper ramp at the head of the deck. The concerns with creating a flipper were that it needed to be strong enough to throw a one inch steel ball bearing three feet up an incline, without requiring excessive force from the player to operate them.
