Situation
In this lab, the team finished the construction of the AEV and began to notice a few problems in the design. The gears didn’t fit perfectly and wouldn’t turn properly. This led to the team scrapping the idea and moving onto a new AEV design. This design was lightweight, energy efficient, and had a servo brake positioned by the front wheel. This optimized the energy usage from the AEV because it was light and didn’t require the propellers to brake.

Team Meeting Notes
Date: 8 – March – 2017
Time: 4:00 pm (Face-to-Face)
Members Present: Jacob Protheroe, Tom Paoloni, Michael Tesmer, Ian Johnson
Topics Discussed: Construction of the Spring AEV
Objective:
After receiving the newly designed parts, the team set out to rebuild the AEV using these parts.
To do/Action Items:
- Construct the AEV – (TP,JP,MT,IJ)
Decisions:
- There are very significant design issues with the spring design. The team decided that going forward, a new design would have to be created.
Reflections:
- Precision is key when creating a complex design that uses gears. The thin axles the team was using and that each custom parts had been made to fit bent very easily, and a very slight bend might mean that two gears don’t line up making the AEV not work. The materials supplied to the team simply were not precise enough.
- Friction between gears was a much greater issue than the team originally assumed. This issue was another killer for the spring design.
