156B Week 9

MAE 156B Week 9 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.

• • Fabrication set to be completed midweek

  • Optical encoder testing has begun

  • Motor control testing wrapping up

  • Begun software reprogramming from Raspberry Pi to Arduino/MATLAB per sponsor’s request

Accomplishments from Previous Week

• • Capacitive sensor tested and working

  • Hnasko air chamber fabricated

  • Hnasko motor mounts designed and most have been fabricated

  • Disk flanges for both labs fabricated

  • Bearings received

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

• • Finalize system testing and packaging for both chambers (Michal)

  • FInal draft of report and poster, and lickometer integration (Philip)

  • Test disk pushing force, disk surface preparation (David)

  • Data acquisition system and user interface (Jeff)

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

• • Hnasko Lab: Wanted Raspberry Pi replaced by Arduino, control should be handled by MATLAB; optical encoder we currently have is good, no concerns about resolution

  • Bloodgood Lab: Okay with transferring from Raspberry Pi to Arduino/MATLAB

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

• • Comment: Look into lighter density foam

    • Action: Investigated feasibility for lighter density foam, none found that were rigid enough, will be using spokes to reduce inertia

Risks and Areas of Concern

• • Concern: Remaining time may be insufficient to implement all desired parts of design

Resources or Information Required but not Available

• • Documentation of large motor

Budget (list amount spent and amount remaining)

• • $2,525.41 spent thus far

  • $974.59 remaining
