Next Steps

Professor Jeznach Meeting

• ☑ Slideshow to guide early meeting
  • ☑ Background info and about us
  • ☑ Our goals
  • ☑ Our skills and experience
  • ☑ What we want to learn overall
  • ☑ Introduce our proposal
  • ☐ Sketch of bot
  • ☑ Plan + overview of the robot
  • ☐ Procedure to gather data and analyze — crossed out in the source (second meeting?)
  • ☑ Speaker notes for every slide
• ☐ Read the research paper and procure some questions
• ☑ Ask about the professor's level of commitment and the type of mentorship she can provide
• ☐ Ask the professor about lab availability
• ☐ Research the professor's background
• ☐ Create hand signs for meeting

Questions

• What would be the best way to properly create a heat map of the concentration? The turbidity sensor does tell how much particulate is in the water, so we can see the spikes; however, it does not distinguish between dirt, bubbles, and microplastic. Our three-step mesh filter also cannot give us the concentration, since it is a combination of a transect.
• Is there any way to sustainably harness energy so we don't run out too fast — i.e., wind, water, or sun?
• What would be the best statistical test to use? Also, what is the best data collection method?
  1. Simple random transect sampling — random placement of transects across the study area, no pre-defined grid
  2. Systematic grid-based transect sampling — a pre-defined grid of transects covering the zone uniformly
  3. Stratified transect sampling — transects pre-defined across convergence and non-convergence strata based on tidal current data
  4. Adaptive cluster sampling — starting with a base grid, then adding more transects in areas where high concentrations are detected

Eventual Tech/Skills Needed

• ☐ GIS mapping software
