Reflectance Sensors

Reflectance Sensors

The reflectance sensors are very important for the AEV project. Without them the AEV could only move its motors for a set amount of time. However, with the sensors the AEV is able to count the number of revolutions of the wheel. With this in mind the total distance traveled can be determined. With the functions goToRelativePostion() and goToAbsolutePosition() the AEV can effectively move across the mount certain specified distances. The distance is important because once the AEV picks up the magnet, the distance traveled with the certain motor speed could be different than without the extra weight.

Below we have pictured the reflectance sensors attached to the AEV.
