Overview of Status of Analysis, Design, Fabrication, Tests, etc.
More designs are currently being researched and prepared for presentation for Bart.
We have also decided to pursue a mechanical timer because of its simplicity and robustness for underwater use.
We are also going to decouple the timer, and more analysis is being done on this system.
Accomplishments from Previous Week
Met with sponsor to discuss new design motivations
More designs were finalized for discussion with Bart.
Met with chris cassidy, told us that electrical is better and that the clock they designed in MAE 3 hasn’t been updated in 20 years. Concerns about mechanical output torque; requires decoupling of timer and output actuation.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Present Bart with design Ideas and to finalize final design choice
Hopefully CAD in the next week or two.
Elementary research into parts and pricing, as well as analysis for timing system.
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Bart did not like boxes because it would cause problems with stacking traps.
Presented the idea that ropes can be coiled and stored without needing to be protected from outside forces.
This led to inspiration for many more designs (clamp, screw/pin in middle system, bungee cord, rack and pinion)
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Asked to look into older project more, it was unfortunately a pendulum based system. However, timing formulas and gear train designs should be similar and can be repurposed
Electrical system not great; thus we are moving on with a mechanical system.
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Mostly stuff like need better pictures, or that they liked the gantt chart.
Risks and Areas of Concern
N/A
Resources or Information Required but not Available
Maybe some more information on timing release mechanisms, and the effects that friction play.
