Final Performance Tests

During the final performance tests, the group encountered several issues that slowed down the process significantly. The code for the AEV had to be written a few times, the battery needed to be replaced in between tests which caused a few more coding problems. The most detrimental was after the group made a small error in the code, resulting in the AEV moving too quickly and colliding with the load which broke one of the propellors. Due to these problems, only 2 out of the 3 final performance tests were able to be completed.

Final Performance Test 1

The first of the final tests went extremely well. The AEV was able to complete all of the tasks without any problems. However, the time that it took for the AEV to complete these tasks was a decent amount longer than that of the class average.

Final Performance Test 2

The second test went well as well, but at the end gate, the AEV stopped too short. This was the only problem besides taking around the same amount of time as the previous test.

Final Performance Test 3

Before the third performance test was completed, the team ran into numerous ploblems. One problem involved accidentally running the code at a speed of 500, instead of 50. This caused the AEV to fall off the track and break a propeller, setting the team back.  Another problem that challenged the group was the fact that the AEV was performing inconsistently, sometimes running into the sensor gate, and sometimes falling short of the sensor gate, although the same code was used. This was hypothesized to be due to the servo motor not activating properly. Once the servo motor was altered, the final test had been completed phenomenally. The graph below represents the Power Vs. Time analysis of the entire AEV final performance run.

The graph shown represents the time in seconds on the X axis, and the power in watts on the Y axis. The higher amplitudes on the graph represent times when the AEV was using more power in order to move, such as times when the AEV was operating the propellers at a higher speed. The lower drops in the graph represent when the AEV is using a minimal amount of power, or no power at all. Such as times when the AEV is coasting or when the AEV is using the servo motor to stop, as the servo motor requires little energy.
