Reflectance Sensors

The reflectance sensors make it possible to control the position of the advance energy vehicle (AEV) through each wheel rotation. This is done by attaching the sensors to the vehicle next to the wheel with two different pieces of reflective tape (shown above). A computer program will record each time the reflective tape is not on the sensor and will provide data when one full rotation of the wheels has been completed. This is very important in the AEV design project as it allows the team to program the vehicle to stop at the gate and loading zone when required.
