Performance Testing
Two models were used in performance testing. However, only one model could be tested for most of the testing as the production of the 3-D printed and laser cut parts was slow. Below is the first model that was tested without the 3-D printed brake arm.

Here is the second model that was test during performance testing. The team chose this as the final design because it allowed precise control over the AEV’s movement via the power brake arm.
