[Shane ] sent in GATech’s senior design final projects, but his Autonomous single player foosball table is awesome. A Java app tracks player and ball via webcam. Then it acts as the opposite player by controlling servo actuated paddles. He’s copied his project to his personal server, just in case the class files get pulled next semester.
The course page is pretty ugly, but the project pages aren’t. It’s worth some time to check out the rest of the projects. The 2d iRobot based mapping system looks interesting, but lets be honest, the hand washing detector should be mandatory federal equipment at every fast food restaurant.
