Re: Lego Mindstorms sensors

I think the ultrasonic sensor should "see" the polycarbonate because the sound wave the sensor sends in should bounce from the polycarbonate and back to the sensor, giving you the distance between the sensor and whatever it is in front or below of.

HiTechnic, a company that makes certified LEGO sensors, sells a Infrared Seeker for the NXT that seeks infrared signals. It is not a very powerful sensor however. Any FTC team should have a Infrared Seeker.
