Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Sealing methods have been and are being tested
Stepper motors are working but running hot and driver uses diff. logic voltage than RPi (new driver coming in tomorrow)
Assembled dome with components inside
Updated CAD to prevent problems in future print
Accomplishments from Previous Week
Tested sealing methods (O-ring, gasket [rubber & cork]) (Damian and Trevor)
Tested steppers - got them working (Michael and Trevor)
Bought drivers (Ciara)
Creating top piece of housing from acrylic sheets (Trevor and Damian)
Printed steering gears (Damian)
Got steering gears to rotate (Michael and Damian)
Put the electronics and stuff in the test housing (Damian, Michael, Ciara)
Soldered RPi/battery connections (Ciara)
Made jig to test 3D printed hole sizes (Damian)
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Print acrylic housing on ProJet (Everyone)
Final assembly of robot (Everyone)
Work on report and website (Everyone)
Make permanent tentacles (Damian & Ciara)

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Asked about micro torque wrench availability for gaskets
No we do not have it
Washers with gaskets
Could try for the final design but not action taken yet
Time concerns - Lots left to do
Focused on getting things done
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Look into using a pipe to avoid waterproofing problems
Will look into buying pipe this week
Focus on propulsion, steering mechanism is secondary
We worked more on propulsion than steering
Try using acrylic sheets to make dome
We tried it and need to seal it better
Risks and Areas of Concern
Steering mechanism functioning properly
Weight distribution and buoyancy problems
Waterproofing
Resources or Information Required but not Available
More access to printers? (Was very helpful this Sunday)
Schedule
Describe upcoming milestone
Final Design Presentation
