The AEV moved faster than expected, depending on the speeds tested braking could be delayed. This adds uncertainty when calculating the distance the AEV will travel. At lower speeds; however, the AEV stopped almost immediately showing that for a more accurate run lower speeds would be suggested.
The reflectance sensors keep track of the distance the AEV travels by keeping track of the number of times the reflective tape passed. This sends the information to the Arduino which records the number of marks the AEV has traveled allowing commands such as gofor and goToRelativePosition and goToAbsolutePosition(c) and others to be executed.
