Foosball Project
Shane writes –

Our senior design project (at Georgia Tech) was an open ended design. We chose to create an autonomous foosball table. The ball as well as the opponent players are tracked in a vision system — a downward looking webcam. All the main processing is done on an 800 MHz pentium 3 PC in Java, using the Java Media Framework. Once the processing is finished, the PC issues commands to a PIC microcontroller across a serial line. The microcontroller then issues commands to servos to move or kick.
