been playing with the Edubot and the optical sensors in this years kit at home for the past couple of days.. and i noticed someting a little pecular about them.

they will sense other surfaces then Retroreflective tape.. i hold my hand in front of them and thet trigger. also.. i built a model of the sensor array we plan for the bot this year and im finding out that the sensors have a hard time tracking white on red. im using construction paper, but i dont have any carpet.
anyone else encounter this problem or a simalar one?

the other thing is.. that im not totally shure about the tracking lines on the field this year, are they made with retroreflective tape or is it just a strip of white duct tape
