 ====Ball Sensor====
 Ball handling is just as important in robot soccer as it is in the real thing. The best soccer players are known for their fancy footwork and hopefully ours will be too! As such, a big goal for the 2008 team is to increase the ball handling skills of the robots. The electrical team's contribution to this goal is the IR (infra-red) ball detection system which detects if a ball is in-front of the robot and both activates the dribbler and notifies the host when there is.

 ====IR Ball Sensor====
-In order to be effective ball handlers the robots must be able to postion themselves relative to the ball for kicking and dribbling. In 2007 this was accomplished entirely using the camera and the off-field controller, but problems with the accuracy of locating the ball proved that a more robust solution was needed. In 2008 it was proposed that the tasks of detecting the ball's location relative to the robot and aligning the robot to the ball would be moved from the off-field controller to the robots,  In order to achieve this goal the electrical team will design a two part system for ball sensing: a breakbeam placed in front of the dribbler, and an LED array for detecting the ball's location relative to the robot's x axis.

Both the breakbeam and LED array will operate in the IR band and will be offset in wavelength so as to avoid cross-talk. The break-beam will be built using discrete parts and the LED will be designed as an expansion board for the main robot controller. The LED array will take advantage of the extra IO pins available on the both the FPGA and the LPC. Below are the design requirements for both.
