Performance Test 1
For Performance Test 1, Erin’s design (Design 2) was tested against the Team AEV design (Design 1). Initially, Erin’s design used two Joules more energy than the Team AEV design, but Erin’s design did not make it up the first hill. Therefore, the motor speed had to be increased by 10% leading to Erin’s design to consume four joules more energy than the Team AEV as seen in the graph above. This was most likely due to Erin’s design being heavier than the Team AEV design. The Team AEV design also had motors configured in an energy efficient way. From this test, the Team AEV design was carried forward.
Performance Test 2
Performance Test 2 compared two different codes for their energy efficiency. Code 1 consisted of using goToRelativePosition() and timing. Code 2 utilized while loops, if-else statements, and getTotalMarks(). As seen in the graph above, Code 2 consumed ten joules less energy than Code 1. Code 2 also stopped more consistently before the gate than Code 1. From these observations, Code 2 was implemented in the Final Performance Test.
Final Performance Test
The Final Performance Test used 146 Joules and took 51.3 seconds as shown in the graph above. The Final AEV Team design was used along with implementing while loops, if-else statements, and getTotalMarks() in the Arduino code. The total cost of the AEV, factoring in the design, energy, and time, was $522,660.
