156A Week 10

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

• • CAD for connection between bridge and chambers is a work in progress

    • Will be 3D printed before presenetation if time allows

  • Risk Reduction Presentation has been started

Accomplishments from Previous Week

• • Basic Analysis for bridge connecting the two chambers has been done 

  • Individual Component Analysis done?

  • Created a skeleton for Risk Reduction Presentation

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

• • Finish Risk Reduction Presentation

  • Get 3D printed prototype of connection for bridge or a CAD animation in time for the presentation

  • Review CAD of original prototype 

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

• • Originally wanted to downsize from 5 to 3 nose ports, now sponsor wants to stay with 5 if possible (3/11 in person)

    • We adjust our design to take into account 5 nose ports, which means our behavioral chambers needs to be wider than planned

  • Automated water system can either be incorporated into the existing raspberry pi or another raspberry pi can be added specifically for water (3/11 in person)

  • We will explore both ideas and see which is more feasible

  • Think of a way to measure the amount of water released each day more precisely (3/11 in person)

    • We will look into water bottles or other devices that allow for more a closer measurement

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

• • Good start for Risk Reduction ideas, but think about Risk Reducing the project as a system and not just the bridge (3/5 in person)

    • We will incorporate our research from our individual component analysis into our final Risk Reduction

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

• • The connection between the bridge and the two chambers must be strong enough to withstand a rats weight walking through it

  • The rats are currently chewing through the 3D printed nose ports

  • Automated water release system, so researchers do not have to refill the bottle every day

  • The size of the screen - big enough for the rats to see from any nose port, but small enough to fit in the screen

  • The size of the chamber

Resources or Information Required but not Available

• • N/A

Schedule

• • Modify/ Finish Risk Reduction Presentation by 3/21

  • Update Gantt chart.

Budget (list amount spent and amount remaining)

• • $0 spent

  • $3000 remaining

Progress on Report and Webpage

• • Filled out Project Management portion

  • Skeleton for Risk Reduction Done
