Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Can read data from the IMU

  • Packaging is a work in progress - almost there

  • Wiring is in progress

Accomplishments from Previous Week

• • Can read data from the IMU

  • The pwm board now works

  • Motor and ESC wires have been cut and soldered 

  • A spreadsheet to track buoyancy has been made and mass measurements have been taken

  • Ducts and the X-mount were reworked to get to the right buoyancy 

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Sam: 

    • Finish the final buoyancy solution

    • Work with Janelle on packaging/wiring

  • Matt: 

    • Re-size the tube

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • Comment: look into using a hemispheric dome for the camera-may relax the size constraint if you can find one. 

    • Result we found one but it's for a 4" tube and the design is too far along to switch from a 3" ID to a 4" ID. Here it is: https://www.bluerobotics.com/store/watertight-enclosures/wte4-asm-r1/#configuration
