We chose the Black 03020 propellers using the pull method because they propelled the AEV the furthest in the same amount of time that all the others did. We found that overall, the pull method is the most efficient method for configuring the propellers. Using the pull method, the propellers were able to move the AEV over a greater distance than when using the push method over the same time interval. The Black 3030 propellers were very close to being the same as the 0320 propellers, however they were much harder to take on and off compared to the 0320 propellers. The Grey 2510 propellers were the worst out of all the propeller configurations. They barely moved compared to the other propellers and consumed the most energy for the amount of distance they traveled. The important takeaways are that the smaller the propellers, the worse the energy efficiency of the AEV. We found that the larger propellers yielded a more efficient use of power. We also found that the time it takes for each configuration doesn’t rely on the configuration rather it relies more on the code. Some configurations were smoother at braking than others, but all were able to brake exactly where told to.
Black 0320 Propellers
Pictured above is our Black 0320 propeller configuration. As stated previously, they performed the best out of all the configurations, being the most efficient with the power use compared to how far it allows the AEV to travel. They are somewhat easy to take off and are the best overall choice for our AEV.

Power vs. Distance Data for Black 0320 Configuration
Using the Black 0320 Propellers with the pull method, the AEV traveled about 1.17 meters over a time period of 10.7 seconds.
(Push Method Data)
Using the Black 0320 Propellers with the push method, the AEV traveled about 0.69 meters over a time period of 10.7 seconds.
Black 3030 Propellers
Pictured above is our Black 3030 propeller configuration. As stated previously, they are comparable with the 0320 configuration giving very similar results in terms of how efficiently they use the power compared to the distance they allow the AEV to travel. They are very difficult to take off and is why they are not the best choice for our AEV.

Using the Black 3030 Propellers with the pull method, the AEV traveled about 1.11 meters over a time period of 10.7 seconds.
(Push Method Data)
Using the Black 3030 Propellers with the push method, the AEV traveled about 0.83 meters over a time period of 10.7 seconds.
Grey 2510 Propellers
Pictured above is our Grey 2510 propeller configuration. As stated previously, they performed the worst out of all the configurations, being the least efficient with the power use compared to how far it allows the AEV to travel. They are somewhat easy to take off, but are the worst choice for our AEV due to the lack in energy efficiency.
