During the third lab, the sample AEV was built in order to be used as a reference in the concept screening scoresheet and the concept scoring matrix. With the sample AEV, a basic code was loaded in the Arduino and did a test run on the tracks. After seeing it in action, the sample AEV is listed as reference in the scoresheet and matrix. The previously made designs in Lab 1 was ranked against it to see if it was better or worse than the sample AEV.
The purpose of this lab was to observe how a sample AEV ran on the ceiling track with a given arduino code and distinguish possible alterations to the AEV that would end up benefiting the group’s final design. The group was able to see how fast or slow the AEV moves relative to the percent power of the motors and the effects of altering the motor acceleration time.
Ultimately this lab introduced the team to the AEV testing procedure, as well as what factors affect the AEV’s performance. The team used the information from the test run, and applied it to their designs to gain further knowledge of what to include in the final design.
Using the sample AEV as a base to compare the design the members created, the members ranked the designs that were created in a concept screening scoresheet and a concept scoring matrix. The ones that the team created are posted below. The final decision was to combine the design B and D together for the group AEV. To see which member created which design, please refer back to Lab 1: Creative Design.
