The following graphs are in demonstration of the power versus the distance of the AEV and the time in which the power was outputted by the AEV. The coding for each trial can be found on the following link:
The power versus distance graph is irrelevant for trials one and two due to errors accumulated with the reflective sensors. The reflective sensors were evaluated after trial one to see if the data had been recorded and when nothing had appeared, the reflective sensor test was performed on the sensors to determine whether or not they were actually working. The test read back that the sensors were working but from the results of the second trial they were still not reading out the distance the AEV traveled. The reflective sensor test was run one more time to ensure that the sensors were working and the third trial read out results of how far the AEV traveled. For trials one and two, the distances were manually read on a measured track to make sure that the distance was recorded in the case that the sensors didn’t work. The total distance traveled in trial one was zero inches due to the AEV not moving with the amount of power put through the motors. The total distance of trial two was two-hundred and seventy-five inches and trial three traveled a distance of ninety-four inches. These distances show that around 14 watts is an appropriate amount of power to be used in order to get the AEV across the entire track without any problems. Another conclusion that can be drawn from this is that the amount of power that the battery can output is more than what it says it can truly output. These conclusions have affected the our approach to the MCR moving forward on how much power will truly be needed to be supplied to the motors of the AEV in order to get the AEV down the track and back.
