Lab 6&7 – Effects of Motor Quantity
One our our main questions was whether two or one motor was more efficient, an important consideration if we want to make the most efficient AEV possible.
The following figures show the results for the advanced R&D tests of the various motor quantity and direction configurations. These tests were preformed with the code found under One_Motor_Test, Two_Motor_Test, One_Motor_Pull_Test, and Two_Motor_Pull_Test under the Code section:
Lab 8 – Effects of Pushing and Pulling
Our secondary question was whether pushing and pulling was better, or more energy efficient. This can depend on design, although if using the same design, this should not matter when strictly comparing energies.
The Following table is a summary of our data gathered.
Push-1 | Push-2 | Pull-1 | Pull-2 | ||
Average | Energy (J) | 16.823 | 30.9494 | 15.036 | 28.4505 |
Distance Powered (m) | 0.42596 | 0.78506 | 0.24145 | 0.7801 | |
Joules per Meter | 39.94189 | 39.50836 | 62.27746 | 36.47032 | |
Standard Deviation | Energy (J) | 0.181086 | 0.691785 | 0.492146 | 0.009192 |
Distance Powered (m) | 0.047639 | 0.035655 | 0.008697 | 0 | |
Joules per Meter | 5.014475 | 2.496614 | 0.205038 | 0.011784 |
Based on our data, we will most likely going forward with a design that uses two motors to pull the AEV as that was the most energy efficient and consistent.
