External Sensors: This diagram shows the RoboReptile's external sensors and their location.


The RoboReptile has several different forms of external sensors. The newest is the "CDS" sensor, it detects if the RoboReptile is hooded or not (or if the amibient light level is low). I have yet to determine exactly what this is, the labeling would suggest that it is a cadmium sulphide (CdS) Photoresistor, but the packaging would suggest that it is actually a Photodiode .

The IR LED's are coupled with the IR Receivers to detect obects to the left and right of the RoboReptile's head. The IR receivers also receive the signals from the remote. The two microphone's allow the RoboReptile to detect loud noises on its left or right. Finally there is a single touch sensor on the RoboReptile's back, this is use only for interaction with humans.
