2021-11-18 Meeting Minutes - Drivetrain

11 Days until Final Design Review (Nov. 29th!)

Aim is to just be changing measurements at this point, filling in the details (spacers, fasteners, tolerances)

Review wheel integration plan
- Update on inner fillet measurements?
- Update on 3D printed hub
- Update on custom wheel research
  - Conclusion: proceed with Wheeleez
- Encoder update....
Review carbon fibre bonding plan
- Summary of bonding paper
- Shear force calculations at joints for epoxy selection
- Update on plan for Saturday
Suspension geometry
- Geometry is close enough to the prototype
FEA update?
- Tested plate with triple the weight of the arm, statically is not yielding, max displacement is 1mm
  - But that's for the full plate and we're expecting a cutout for science + lightening holes
- Need to still determine areas of focus
Sponsorship items update?
- SKF → ASAP
- Demtool
- RLS → dealt with
- 3D printer sponsor?
