156B Week 5

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

• • 1st prototype of behavioral chamber and home chamber have been built

    • Behavioral chamber : the top and bottom pieces have to be modified to fit better

    • Home chamber : the home cage with a bottom can now be cut

  • The adaptor pieces have to be modified a bit, but overall works the way we intended

  • The pump for the water delivery system works with the push of a button

    • Must be calibrated to release 15 mL

Accomplishments from Previous Week

• • Laser cut all parts needed for behavioral cage

  • Machined parts

    • Rectangle in our home cage 

    • PVC tube with slots on either side

  • Assembled parts for water delivery system

Goals for Next Week. Use specific and measurable objectives.

• • Calibrate our water delivery system to be able to measure out 15 mL

  • Get electronics from inside the behavioral chamber from Prototyping lab

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

• • The 4 in. diameter PVC was a good size (4/29)

  • Make sure the gaps are small enough so the rats will not be able to escape (4/29)

  • Continue on without the pieces from prototyping lab and they will be added on when they are ready (4/29)

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

• • Ask sponsors if 4 in. is maybe too big? Go back to 3 in or 3 1/2 in diameter PVC pipe (4/23)

  • Make an instructions guide for how to assemble adaptor piece (4/23)

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • N/A

Risks and Areas of Concern

• • Gaps in between PVC and adaptor are big enough for a rat to fit in and escape

    • The next iteration will be adjusted to account for this

  • Water delivery system needs to precisely deliver 15 mL a day

Resources or Information Required but not Available

• • N/A

Budget

• • Amount Spent: $202.44

  • Amount Remaining: $2797.56

Progress on Report and Webpage

• • Engineering Standards has been updated on the report

Schedule

• • Upcoming milestone:

    • Proof of Concept Presentation

    • Get behavioral chamber parts from Prototyping lab

    • Build a 2nd iteration of our chambers

    • Incorporate working water delivery system into our home chamber.

  • Gantt chart:
