Week 9
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Finished manufacturing Design 1. Vertical Stabilization with human intervention was achieved. New motors/servo have been purchased. Design 2 almost finished manufacturing.
Accomplishments from Previous Week
Final Report draft updated
Open loop hybrid control achieved- vertical stabilization without disturbances.
Design 2 is nearly finished. Only need to CNC, laser cut, and lathe 1 more part on each machine.
Servo Arduino Code Updated
Encoder processing code created.
Safety box completed.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Manufacture motor mounts for Scotch Yoke: Jack, Paul
Get IMU working on crank mechanism: Allyson
Combine rpm and servo angle code to automate stabilization: Allyson, Wei
Improve arduino wiring: Jack, Wei
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Was excited about the open loop hybrid control- instructed us to now implement closed loop control. To do this, we began working on the IMU mounting.
Wanted us to give him nice photos and videos of the designs functioning to show early at a presentation.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
No comments last week (presentation)
In-Person, 5/14:
Recommended loctite for screws which were walking out. We were able to find some in the machine shop, but we have not used it yet as we have been continuously servicing and modifying the system.
Recommended that metal clamps were used such as c clamps, as we mentioned our plastic clamps weren’t working great. A large metal C-clamp was ordered
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Would have liked to see Design 2 functioning.
Slide making issues such as too much information on a slide, text color being hard to read, and bigger, more clear diagrams.
Wanted to learn more about vibration dampening methods and closed loop control.
Wanted us to slow down on a few of the slides.
Risks and Areas of Concern
Vibration of the mechanism could cause fatigue and noise. Screws also walked out of the design, and will likely need loctite.
IMU may be difficult to attach and provide proper data feedback. Wires may also get tangled when spinning around
Resources or Information Required but not Available
Schedule
Finish and test Design 2 by the end of week 9.
Budget: $1,439.62 spent, $1,560.38 remaining.
Progress on Report and Webpage
Final Report draft updated, and comments considered.
