The optical sensors we got had a yellow body and ... yeah I believe they had a red lens.

We took a long look at using them to lock on a goal at power up so that we could autonomously drive to the goal and lock on. Like Andrew posted, we thought we might gain a sec. or so advantage. When we checked the sensor specs against the distance from our starting position to the center-line of the field, however, the sensitivity of the sensors rolled off big-time about 4ft shy of the reflective tape. So, we'd have to start in manual, get a lock on multiple sensors and triangulate. Since we got ~12fps in high gear, we figured we'd be there by the time we got a good lock! In the end, since we were pretty fast, we relied on pure speed and a beefy front grabber, and just rammed the goal at full speed. We did end up using the optics, though, as part of a tread speed measuring circuit.
