My senior design project required us to use two rovers running FreeRTOS with sensors of our choice to do something interesting. We also had a requirement of using a very basic computer vision camera and wireless communications. We ended up making a pacman game with one ghost rover and a pacman rover. Pacman was controlled via a PC while the ghost was given pacman's position from a CV camera above the play field and implemented A* (which me and another teammate were just learning about in our Intro to AI class). It was really fun and we got some extra points for tying in something from another class which was cool.
