Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Sponsor meeting on Sunday: crossed out some ideas and started on establishing a prototype
Pig eye experiment starting on Wednesday
CAD in progress to have an acrylic model by Friday
Accomplishments from Previous Week
Discussed our options and alternative sensors at the sponsor meeting on Sunday
Two design solutions so far using ultrasonic distance sensors
Sketches and CAD drawings being done
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Experiment with pig eyes: how the layers of eye and tears respond to difference sources of sound and light
Decide on the sensor and preferably put in an order
Weekly sponsor meeting on Monday at 6pm starting next week
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Magnifier + accelerometer option: semi-digital; prefer a more modernized version
Scanning the front contour with a sound sensor
Scanning the profile view with a laser
Prefer ultrasound or ultrasonic rather than any form of laser -- even the safe "class 1" lasers have the assumption of being harmful
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
PowerPoint notes: summarize and bring to the meeting
CAD or clear sketches required
Accuracy of ultrasound/ultrasonic sensors
Experiment with camera and profile pictures -- what can a camera show fundamentally?
Start off with sensors only without worrying about other constraint -- learn the physics
TA Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Meeting with Pedro on Tuesday at 1pm
Ultrasonic sensors: how do they react on curved surfaces?
How to use this prototype and risk reduction information for the final design?
Click on the tips of each eye and scan around that region.
Accuracy on ultrasonic sensors? Check the spec. sheet
Testing protocol must be recorded closely -- experimental procedures and a write-up
Presentation: state problem, functional requirements, start with a risk reduction (why we needed a new RR), explain both plans (ultrasonic sensor idea and the plan b with the magnifier)
Label and provide various views on the CAD
Pros and cons of each plan (automated v. semi-digital)
Ordering, manufacturing any components? Steal, acrylic?
Pick the motor then search for an encoder -- add this to the area of concern of ppt.
Have a draft of the ppt. for Thursday meeting
Clearly explain why we are not using lasers anymore
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
Accuracy on ultrasonic sensors
How different layers of human eye reflects the sound or light -- non-solid, curved surfaces
Resources or Information Required but not Available
Need to purchase the sensor from a third party -- research still in progress
Schedule
Pick up pig eyes from the Shiley Center on Wednesday (Riaz & Jacob)
Pig eye experiment with the acrylic prototype for the rest of the week
Budget (list amount spent and amount remaining)
Ultrasonic sensor for testing purposes
Pig eyes
Progress on Report and Webpage
PowerPoint started on google drive
Webpage description details being finalized by the end of this week
