AbstractThe EECE474 Pac-Man project is a robotic counterpart of the computer game, Pac-Man.As in the original Pac-Man game, the Pac-Man robot, controlled by a player via a RFlink, moves around the maze collecting LED “dots” while avoiding contact with theGhost, which is an autonomous robot capable of tracking Pac-Man’s location in themaze. The microcontrollers onboard the robots are responsible for reading the wallsensors and controlling the stepper motors to perform precision turning and stopping. Tosimulate the dots being “eaten” by Pac-Man, the maze dot modules, equipped with lightsensors are capable of turning off the LEDs once Pac-Man passes through. The numberof dots collected by Pac-Man is shown on the LCD display. The tracking mechanism isachieved by mounting IR receivers onto the Ghost to detect Pac-Man’s IR beaconsignature and using such information to compute the shortest path to reach Pac-Man inthe maze. Contact sensors are also used to detect collisions between Ghost and Pac-Man.
