Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
1/17/2020 In person
we have 3 different types of genetically modified mosquitoes
one that expresses green florescence (Green eyes)
one that expresses red florescence (Red eyes)
one that expresses blue florescence (Blue body)
sponsor also wants to figure out which color is best for our sorting design
want to sort pupae from stage 4 larvae, on top of males from females
optional to sort pupae from stage 4 larvae if our current design can handle both pupae and larvae
83% return on undamaged pupae/larvae is acceptable
If damaged, the pupae/larvae turn blue
stage 4 larvae are 1 cm long, more of a long shape
pupae are 4-5 mm long, more of a round shape
De-ionized water (the water the mosquitoes are raised in) comes from a faucet-like fixture, so there is plenty of water
intensity of color expressed is stronger in larvae than in pupae
larvae still need food, but can go a maximum of 12 hours without it
cannot have moving water with mosquito food because it may cause food contamination, bacterial growth, and cloudy water
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
1/16/2020 In person (during presentation)
Use a light material (Teflon) to reduce friction in the revolving door portion
Make sure the material we use is non-toxic to pupae
Make sure the sponsor know our current design and is approved for pupae safety
1/16/2020 In person (during lecture) See Lecture Slides
make a list of standards that the project follows
make sure the project adheres to a standard
make CAD drawing to a standard
1/16/2020 In person (after class)
Risk reduction needs to be done, physical test with flexible tubing and manual door to ensure pupae aren't clipped.
1/17/2020 In person (Ed Progue)
3D print the revolving door on the Connex (ask Chris Cassidy first)
Connex can print a variety of materials, including flexible ones
Connex can print very fine layers, great for our pupae/larvae sorting application
Use a servo motor to make the revolving door turn 90 degrees at a time
can buy waterproof servos
build a housing around the servo
Design the edge of the door such that it will not crush pupae/larvae between the door edge and the entrance wall
use brushes at the edge
use flexible material
use geometry
any of these, or a combination would work
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
1/16/2020 In person (during presentation)
Make the revolving door using STL 3D printer
Make sure the revolving door has geometry such that it will not crush pupae on accident
1/17/2020 in writting
make door out of mesh to allow water to flow through
right hand threads
