156B Week 7

MAE 156B Week 7 Progress Report

Project Title: Locomotion Monitoring System for Mouse Cognitive Behavioral Task

Sponsor Name: Bloodgood Lab and Hnasko Lab

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

• • Optical encoder housing designed, fabricated, and tested

  • Disk cut and tested (testing paper covers)

  • Acrylic bought and cut

  • Some components have arrived (skeleton frame for air chamber assembled)

  • Lickometer hardware designed

Accomplishments from Previous Week

• • Optical encoder housing 3D printed

  • Acrylic purchased

  • Acrylic and gaskets cut

  • Frame for air chamber stand assembled

  • All t-slotted aluminum bars for Hnasko and Bloodgood systems ordered

  • Confirmed with labs that capacitance of mouse is similar to that of a human, specifically that a touchscreen can register a mouse’s touch

  • Confirmed that grounding a mouse is feasible but requires 2 weeks notice to add to surgical procedure

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

• • Assemble Bloodgood air chamber and integrate impeller (Michal)

  • Design flange bearing for disk (David)

  • Assemble liquid reward delivery system hardware (Philip)

  • Implement impeller power control hardware (Jeff)

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments

• • Bloodgood lab might want real time data

  • Hnasko lab might need higher temporal resolution

  • Confirmed that lickometer design was valid

  • Specified that Bloodgood lab track needs 6in tall walls on the side

Instructor Comments from Last Meeting and Actions Taken to Address these Comments

• • Comment: Run time of experiments for data storage concern

Action: Spoke with sponsor who verified maximum experiment run time of 1 hour

• • General comments about report and web page

Action: No current action however edits in the report will reflect feedback

• • Optical encoder performance for varying disk height.

Action: No further action however testing will be conducted the following week

Risks and Areas of Concern

• • Testing requirements for validation of system for the course

  • Inability to air seal motorized impeller

Resources or Information Required but not Available

• • Stand-in 48V power supply to use while waiting for final product power supply

  • Proper use of vibration dampening grommets

Budget (list amount spent and amount remaining)

• • $2,030.22 spent thus far

  • $1,469.78 remaining

Progress on Report and Web Page

• • Report:

    • Instructor comments reviewed

    • Bloodgood lab added to title, instructor name corrected
