Proposal Review

Strengths

  • Well written proposal. The idea is clear, and the youtube link is a significant help clarifying the goals.
  • Objectives are actual deliverables, which can be individually evaluated.
  • Thorough study of the challenges ahead of the team.
  • Good Gantt Chart formatting.

Weaknesses

The main problem with this proposal is the lack of robustness of the potential demo. I can see this prototype working well under certain conditions, but I fail to see how a simple laser sensor will provide enough data to find the "perfect angle" to pour the liquid in the glass. Moreover, the current idea uses the laser sensor as an ON/OFF switch to detect a particular froth height. I don't see how an ON/OFF switch will help you "adjust angles as more soda accumulate in the glassware". Shouldn't you use a distance sensor in this situation, pointing towards the interior of the glass?
