156B Week 4
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Building around Hematek device with t-slots
Connected the linear guide to a stepper motor
Testing smearing with the linear guide
Accomplishments from Previous Week
Device (Cindy)
FEA analysis on structure to determine the best support materials/design to use
Cost analysis on materials for the device
Aluminum sheet vs t-slots
Smears (Kevin)
with PTFE, polystyrene, aluminum, and brass rods
risk reduction for a slide dispenser
Motors and electrical (Marco)
wiring motor to linear guide
test code for sensors and motor
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Update new report sections - all
Cindy - unloading system
CAD of final device with t-slots this Friday
Buy materials/order parts this weekend
Kevin - smearing
CAD rough draft by next Monday
Marco
Finish test code for linear guide
Christopher - CAD tutorials
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Comments via email
Try blood that has been in citrate tubes instead of EDTA
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
From last meeting (4/18/19)
Presentations
Make the names on each slide bigger and easier to see
For the smearing
Automated flexible smearing dispensing would work best
to automate, use mechanism similar to that found in gumball machine
continuous ejection
Electrical
need a switch for each motor
potentially could use solenoids as drivers for gripper
