(This page is in progress as the research is currently in progress, come back to see the exciting discoveries that we find.)
1. Pros and cons of power braking vs. coasting.
Power Braking
Pros: Cons:
Much more time efficient. Uses more energy to stop AEV
Pretty reliable for predetermined stopping distances. Slightly less stable/unsafe, especially at higher powers.
Coasting
Pros: Cons:
Energy efficient, uses zero energy. Stopping time is inefficient and unreliable
More stable and safe when stopping. Not reliable for predetermined stopping distances.

3. Address which method your team will use moving forward with supporting evidence.
Our team will be using power braking instead of coasting. Coasting causes the AEV to travel too far, too quickly. While it is power efficient since it relies completely on friction to stop the AEV, this power efficiency is far outweighed by the long stopping times and distances. Power braking can still be relatively power efficient if programmed correctly and the short stopping times and distances are a requirement for meeting our design goals and for addressing the purpose of the AEV.
