156B Week 7
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
detailed CAD of entire gyroscope has been created
precessing frame assembled
tripod has arrived
assembled wheels and tripod to base
Proof of Concept Presentation completed
decided on square 80/20 design for nutating frame
need to find bearings for precessing frame still
created simple animation of detailed CAD model
Accomplishments from Previous Week
Proof of Concept Presentation
assembled precessing frame
completed detailed CAD
Goals for Next Week (list names after each item). Use specific and measurable objectives.
update CAD assembly with - Steven
add handle to base
tweak design on precessing frame to reflect what we have decided to do after talking with Ian
assemble nutating frame to gyrowheel with bearings included - KC and Cross
assemble precessing frame to nutating frame with bearings included - KC, Cross, Aki
assemble precessing frame to the base with bearings included- Aki and Steven
remaining miscellaneous assembly - Everyone
Preliminary Design Review Presentation - Everyone
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
5/8/18 in person - Prasad would like pictures of our progress for our next meeting, and the meeting after that would like to meet in our workspace to see what will hopefully be a finished gyroscope in person
5/15/18 in person - told us not to worry about implementing sensors because of time constraints, focus on completing a functional gyroscope
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Proof of Concept Presentation comments 5/7/18 via email -
concise overview of project
figures hard to understand still
have a detailed CAD to work with now
slide discussing wheels for base was especially hard to follow
predict nutation values in addition to precession values
show why torque is applied
focus on machining gyroscope right now
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Proof Concept Presentation comments 5/7/18 via email -
need clearer explanations
CAD animation to demonstrate
goal of the device was unclear
display our progress better
better distribution of speaking roles
Risks and Areas of Concern
attaching the base to the precessing frame with bearings might be difficult
pole is strange size, 32mm is not a common bearing size
Resources or Information Required but not Available
none
Schedule
Describe upcoming milestone
complete as much machining as possible by the end of the week
hopefully have an assembled gyroscope sometime next week (Week 8)
Update Gantt chart.
Budget (list amount spent and amount remaining)
At the beginning of the week we have spent $710.37
We made two orders this week bringing the total up to approximately $900
We have a flexible $1000 budget
Prasad said actual budget ceiling is $2000
Progress on Report and Webpage
completed rough draft of report and webpage
need to update report and webpage draft by this Friday?
