*156B Week 1
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Initial CAD model of the Gyroscope has been completed
Risk Reduction experiments completed
a full-size prototype of the gyroscope has been built
simulations of gyroscope nutation and precession were conducted
parts have not been ordered
decided to use bicycle wheels instead of flywheels
Risk Reduction Presentation completed
peer and instructor comments were reviewed
Accomplishments from Previous Week
Risk Reduction Presentation completed
uploaded to website along with notes from Risk Reduction simulation analysis
peer and instructor comments reviewed
schedule new meeting time with our sponsor
individual component analyses have been started
Goals for Next Week (list names after each item). Use specific and measurable objectives.
complete individual component analyses by Friday of this week
decide on inner wheels for gyroscope, order them so they arrive before next week
begin ordering other parts for the base as well
Each team member finished their own presentation for Boomerang dynamics analysis to present to the sponsor during the weekly meeting
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
sponsor requested that presentations be given this week to demonstrate each team member's understanding of boomerang dynamics
sponsor also requested the team to analyze the inertia of the innermost gyrowheel
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
3/20: comments from Risk Reduction presentation:
Professor Delson would like us to decide where on the gyroscope the motor for the gyrowheel will be
how did we address this?
Professor Delson asked us to post the equations from on Risk Reduction analysis on our website - as of now they have been posted along with the Risk Reduction Presentation
Professor Delson asked us to better explain the connection between the teardrop path and nutation and precession
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
3/20: From Risk Reduction Presentation comments:
we need to find a way to better explain the connection between nutation and precession
why did the nutation rotate to the opposite direction of the torque?
Risks and Areas of Concern
what the dimensions of the wheels should be to achieve a 10 diameter turning radius
motorizing gyrowheel
Resources or Information Required but not Available
solutions of the gyroscopic equations
Schedule
Describe upcoming milestone
this week will order gyrowheel parts and start working on designing and building the base of the gyrowheel with wheels for the desired turning radius
Update Gantt chart.
Budget (list amount spent and amount remaining)
we have not spent any money yet
We have the complete $1000 and $600 machine shop expense left
Progress on Report and Webpage
report has not been started
individual component analyses will be completed this week
Webpage progress:
team photo uploaded
project management pages are up to date
Risk Reduction files have been uploaded
