2 – Reflectance Sensors

Reflectance Sensors:

The reflectance sensors serve as the primary source for recording the distance the AEV travels by using the reflective tape on the wheels. The information the reflectance sensors pick up is transferred to the Arduino, which records the number of marks per revolution of the wheel. This can then be converted to inches/mark (knowing the circumference of the wheel) in order to record the distance the AEV traveled. Knowing the distance the AEV travels is important because it will allow our transportation system to successfully travel the tracks safely there and back.
