Our Detailed Design stage has facilitated the finalized designs of sub-system structures alongside their respective test plans, finishing off the first major milestone of the project. The focus of our design remains a semi-autonomous player piano device capable of assisting a human pianist in playing a piece, with a user interface, full autonomous support, among other requirements. The primary result of this section are designs ready for execution transitioning into the Spring semester.
Over the course of this meeting, we will be going through the topics listed in the agenda above. This will begin with a review of the project definition, including customer and engineering requirements, and our progress in iterating design processes to this point. Each team member will then talk more in depth about the subsystem or process that they have focused their efforts on in this phase, including any work they have done with feasibility, schematics, and/or prototyping. Furthermore, test plans regarding these designs will be discussed as they are finished with prototyping or geared to occur in the Spring. We will then review our current bill of materials and any items we will be looking to purchase at this point. Next up will be our continued work on developing process flowcharts and assessing risks associated with this project. Finally, we will update you on our project schedule and review our plans for the next phase.
If you would like to review the work we have completed during this phase, feel free to follow this link to the Detailed Design page in Confluence:

Agenda and discussion notes
| Time | Item | Who | Notes |
|---|---|---|---|
| 5 min | Background, Agenda, Review of Progress, CRs, ERs | Steven Petrick | N/A |
| 5 min | Risk Assessment | Josiah Martucscello | For all subsystems: describe what the failure modes are, try to ensure open failures (nothing breaks) Be ready for things (keys) to not be perfectly flat Ron liked overview of risk assessment: if it's not on the list he isn't really thinking about it Assign a person to each risk (so there's someone to "yell at") |
| 5 min | Sustain Pedal Design | Josiah Martucscello | Sustain pedal design will stay mostly the same as previous w/ minor adjustments Ideally, have things fail safely if they do fail, look at incorporating breakaway components |
| 5 min | Frame and Solenoid Mechanics Design | Jeffrey Seamon | Look for lower durometer o-rings to reduce buzzing, test to see if better w/ or w/o springs |
| 5 min | Solenoid Electronics and Power Design | David Anthony | N/A |
| 5 min | Feedback System Design | Nick Besley | Calibration should be based on minimum volume threshold Missing buttons due to board size, will code for all buttons/attempt to get larger boards Make sure missing buttons won't result in a failure |
| 5 min | Server/Frontend Design | Steven Petrick | Can we record during playback (i.e. when human is only playing 1 hand) → Yes, in development Make sure we have differentiable volume: may need different firing start times, keep delays in mind |
| 5 min | Bill of Materials | David Anthony | N/A |
| 5 min | COVID Contingency | Jeffrey Seamon | The more specific a test plan can be, the better in case of change in access, Ron wants updates at 2 checkpoints (see Decisions Made below) |
| 5 min | Updated Schedule/Plans for MSD II | Nick Besley | Communicate testing requirements among team to avoid delays Jeff is also Ron's piano tuner, definitely pick his brain |
| 5 min | Thank you, Questions, Approval | Nick Besley | Ron likes the detail, but schedule longer reviews if we continue at detail level (went over time) |
Presentation
The following link leads to the presentation given for the review: Detailed Design Review Presentation. A PDF version is here.
Issues Raised
- Ron would like to be more involved in discussions on COVID contingency
Decisions Made
- Approval given to proceed to MSD II - Build and Test Prep Phase
- Provide update to Ron on COVID protocol/contingency in mid-January before returning
- If any change in the ability to work in-person occurs, a meeting will be promptly scheduled with Ron to discuss a plan for revised work and deliverables
Action items
- Team will complete peer evaluations.
- Each member will create a failure mode analysis for their subsystem and the overall device
- Team will conduct the end-of-semester gate review w/ Jerry (guide) - 12/2/2020
- Continue to reach out to Catherine Lewis for possible collaboration
- Provide Ron with COVID update - mid-January
