Meeting Notes 10/10/12

Meeting Type: Advisor Meeting

Attending:

Advisor(s): Dr. Clark

Members: Kyle, Sondra, Stuart, Greg, Santi (L), Darryl

Excused: Alex (sick)

Action Items

1. MEs: Perform a weight and balance analysis for next week
2. MEs: Do buoyancy calculations (it’s okay to use estimates for now)
3. ECEs: Test the other thrusters for next week
4. ECEs: Test as many sensors as possible for next week
5. Design and perform test on compressed air system as soon as feasible

Meeting Topics

• Overview of current testing and prototyping progress
• Target: have something moving around in the water by the end of November!

Important Notes

• Dr. Clark was satisfied with what we’ve done thus far
• Dr. Clark advises that we do not start the meat of the project until we’ve tested everything and figured out how it works
• When testing waterproof seal, don’t forget to pressure test as well
  • Stick a weight inside and pull it back up with a rope or something
• We should stick an Arduino in our waterproof prototype once we’ve made sure its safe
  • Pop a thruster on with some C batteries

Transcript (Notes)

• Went over presentation with Dr. Clark
  • MEs have completed wooden prototype
  • Sondra and Kyle have done a back-of-the-envelope thermodynamic analysis
    • Estimate that fan should be strong enough to keep internal temperature at approximately 120 degrees F
      • (assume max operating temperature of electronics is 170 degrees).
    • Additional fans could increase cooling by about 60% if necessary, good margin of safety
  • Darryl and Sondra have determined operation of DC thrusters, had unedited video to show
• Dr. Clark wants a weight analysis
• Checked that we have travel budget
• Suggests we lower height of box
• Should probably edit our videos before posting them inline
• Test the sensors
• Test the compressed air systems
• Test the Arduino to motor stuff
• We should do the meat of the project after we’ve tested stuff
• Try to get something moving around in the water by November
• Pressure testing
  • We need to figure out how to get it down
• Do buoyancy calculations
• Stick an Arduino in our waterproof prototype
• Aside: will start tracking latenesses in attending field
