An Implementation of Pacman Game Using Robots

As the field of robotics are advancing, robotics education needs to consider technological advances and societal level of interest. Realizing computer games in robotic platforms is one such technological advance for educating students in robotics science. Realizing computer games in robotics environment is still a challenge due to high investment factor in developing robot models. However the effort can lead to the enhanced interest in robotics education and further involvement in science and technology careers. Young gaming enthusiasts are aware of different playing strategies used in the computer games. If the course curriculum uses integrated approach by building a game in physical robotic environment, students’ strategy developing skills are tapped and students can get jumpstarted in learning course with interest. Algorithms developed by students to realize the game, could find similar real world applications. One such popular game, Pacman is implemented using two iRobot Roomba robots. One robot is considered as Pacman, which escapes from other robot. The other robot, referred as Ghost, tries to attack Pacman. Network camera was used to find robot localization. Interprocess communication was included to share the data among different processes. The programs for Pacman and Ghost robots were built using Player/Stage, an open source package, compatible with iRobot platform. The algorithms were prior tested in Player/Stage simulation platform before implementing with real robots. The partial success of Pacman game in robots is discussed in the paper. This attempt should encourage in realizing more computer games in robotics education curriculum and generate immense interest in robotics education using low cost ready to use robots.
