The goal of this MQP was to design, test and build a fully mechanical computer capable of playing tic-tac-toe against a human being. Our team aims to prove that old school technology still has a place in society today. Our design includes numerous methods of mechanical motion that are found in many designs today such as an escapement, gears, racks and pinions, and hydraulics. The machine was built almost entirely in the Higgins machine shop, except for a couple parts that were either cut with a water-jet or purchased. Our design uses an indexing module to detect position and data stored on a physical punch card to produce the best strategic answer. If the user makes the first move, the computer will never lose, only win or tie.
