Updates/Blockers

Please update me on the progress you’ve made the past week. Do you have any blockers?

Workday Review

• drivers sized → driver model can be finalized this week

• first frame iteration finished → simming to begin

• initial composite research finished → sandwich panel design and mount design next

• steering wheel designs (daybreak and nextgen started)

• critical hardware back in car and harnessed

• mock cooling intake to send to regs

Next Workday Plan - please break tasks down into sub-tasks

• start simulating frame → get initial data for first iteration

• create initial design ideas for frame jig

• continue working on steering wheel designs

• finish up daybreak pedal box changes (test pedal jig, finish design)

• start work on next gen seat

• manufacture mock module

• characterize a few battery cells and bin

• have all battery box panel cutouts finished and dxfs created for waterjet

  • only layups will be a blocker then

Daybreak Progress?

• Created a preliminary design (CAD model) of the radial tubular intermediate steering shaft constraint

nah

• made intake mock before finalizing to get checked by steve and dan

• car can drive theoretically

  • need to pump tires

Questions people want to ask:

• for daybreak → need master cylinders from car to test new pedal ratios and setup, so when can we take them off daybreak?

What do you need from me this week?
