General Ideas/Thoughts

• I know we are pivoting away from lecture based learning, but should we have at least one lecture on CAD best practices for example? Or are we removing lectures entirely

• Length of onboarding process: around 3-4 weeks to allow ample time to form solid foundation

• Should we have people learn on their own? Since there isn’t enough time for one-on-one tutoring, is shadowing returning members while doing design work a good idea?

• Assigning documentation and external resources?

• Starter projects from Daybreak?

• Philip’s two stage starter project idea?

Aeroshell

Strategy:

Curriculum:

Fergo/Structures

Strategy:

Trial by fire (with help as needed)

Dive straight into making a simple part following ASC and VR3 guidelines, experimenting and asking questions as you go along

Curriculum:

• Some sort of introductory slides on the systems and what we will utilize in each system

• 2-3 weeks of designing a simple part start to finish, potentially 3d printing the parts at the end

Dynamics

Strategy: 2 weeks of independent study throughout the week and discussions and applications on workdays.

Curriculum:

• Discussions with Jacob about content from classes like Solids

• Each subsystem looks into different things

  • Suspension - Double wishbone vs Trailing arm

  • Steering - 3-wheel steering vs 4-wheel Ackermann

  • Unsprung - First other teams unsprung components like hubs and uprights. The purpose of those and then generative design and Ansys

Electromechanical

Strategy:

Curriculum:

Demold top shell

• Milestone: Deadline

• Ex.: Aeroshell mold sent out: 12/10/24

Demold bottom shell

Frame welded

Frame validated and ordered

• Driver dimensions taken

• Seats molded

• Frame Design drafted

• Ergo Parts (pedal box, steering wheel, ballast box, etc.) drafted

• Frame ordered

• Frame welded

• Ergo integrated onto frame

Pedal box assembled

Drivers set in stone, driver model created, pedal design validated and ordered

Dynamics geometry decided

Onboarding/Training

Recruitment

• Training: 10/12/24

• Preliminary Designs: 11/9/24

• Final Designs Ideally: Before we leave for winter break

• Final Desings FINAL: 2/15/25

• Manufacturing Begins: 2/22/25

• Manufacturing Finished: Before start of winter break of 2025

• Integration starts depending on other systems
