The Preliminary Design Review (PDR) is a detailed report discussing the team’s process and conlusions drawn from the Performance Test 1 (PT 1) lab. In PT 1 lab, two different Advance Energy Vehicle (AEV) designs were built based on the input and knowledge gained from prior labs. Both designs were tested on the assigned track using the same Arduino code developed beforehand. The purpose of this performance test was to determine the final AEV design that will operate with the least energy cost under the same Arduino code and scenario on track. Quantitative data gained from the actual testing of both designs on the track will be analyzed by the students in order for further decisions regarding the AEV design to be made. The students will be tested and evaluated in terms of their experimental process, problem-solving, and data-analysis skill in this performance test. This PDR will include the experimental methodology of the performance test, which consist of the specific steps carried out and the equipment used by the students to complete the tasks in for the performance test. In addition, every qualitative and quantitative results from the tests are then presented and discussed by the students, followed by the conclusions and recommendations drawn from based on the test’s results. Based on the yielded data and observations, it was concluded that there were many factors that could be factored in the determining the most energy efficient AEV prototypes, and the knowledge from past labs were integral in order to achieve the goal of this lab. From the lab, the team had concluded that the most energy efficient AEV design was Prototype 1 with angled “wings” and 2 propellers that were in the 3030 pusher configuration when it began moving on the track. Refer the PDR below for a more detailed information on the PT 1.
