Team J’s AEV was able to safely complete the task, however it was not consistent. An ideal run would have the AEV using around 226.3 Joules (actual was 228.9) and completing the task in around 48 seconds (actual was 48.5). The final AEV build was relatively cheap costing only $162,760. An ideal run of the AEV would cost $370,150 in energy and time costs. This would result in an average cost of $562,910. The actual cost due to accuracy and variation was $607,793.33. Team J hypothesizes that the reason for the error was battery inconsistencies between runs. In the future, more efficient and consistent battery possibilities should be researched to allow for consistent runs.
