Reliability
Having worked with other optical sensors while I was at HP, I know from experience that these kinds are VERY reliable and VERY durable. The rest of the machine will fall down and the optical sensors will still work... HOWEVER!!!! I havn't tested them yet and I'm wondering if there could be:
1) A problem with cross emitter false readings... that is... instead of tracking the reflection from the tape, tracking the emitted light from someone elses sensor. So instead of finding a goal, you find someone elses robot! This depends on how narrow and how polorized the beam can be. I'm checking...
2) (You didn't think there would only be ONE problem did you?) How good they are at rejecting ambiant light sources like sunlight coming through a window in late afternoon. Sensors are usually used in fixed locations with known light conditions, so the wilds of FIRST tents could be a problem... looking into this also....
Best of luck!
