Power vs Time graph from Preliminary R&D lab 4:

This graph represents the power usage while the Arduino ran the program. Several things can be inferred about the behavior of the AEV during the program

First, the gradual climb from the “0.00” second mark shows the Arduino motors powering up until it hits about 3.25 where it levels off at around 6.67 watts

From there is then drops, showing a decrease in motor speed, to around 4.2. The spike in energy usage is the reverse of the motors, and the sharp drop is when the code applied the “brake” function to stop the motors

Power vs Distance graph from Preliminary R&D lab 4

The Power vs Distance graph shows that while the motors were running the AEV did not have any significant change of distance. This is accurate with visual confirmation when testing the AEV on the overhead track.

Coding for Power vs Time and Power vs Distance (Same code was used for both graphs):

// Run motor one at a constant speed (23% power) for 2.5 second.
