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)

Goals

  • 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?
