Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Version 3.2 was improved to stabilize the structure when opening the door
The squeaking sound was eliminated
Proof of concept for mechatronic option was completed and successful in time to show the sponsor
Accomplishments from Previous Week
Arduino code was completed and is functional
Parts were borrowed from Steve to show that the mechanism works by coupling the motor to the shaft of the handle
The optical interrupter triggered the motor to turn for one sticker only successfully
Steve helped us build the circuit including a comparator to read digital values instead of analog
Modifications to the physical prototype were made as planned by placing a tapered bearing on the top shaft, stabilizing the bolts to prevent the shaft from bending when the door opens and finding the cause of the noise
Opening/Closing the door was made easier
Performed sounds test for current material
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Finish logistics
Work on the manufacturing plan (Chris)
Finish the movie of the final product (Aliya)
Improve the CAD (Ngoc)
Concretize the mechatronics solution (upload code, circuit...) (Shancheng)
Do some research about patents (Team)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Sponsor was really happy with the prototype. We presented in front of a board of about 10 doctors and got some helpful feedback (although the meeting was short) 06/05 - in person
Sponsor asked us to look into patenting
