2021-10-07 Meeting Minutes - Drivetrain

7 Days until First Draft CAD Due!!!

CF testing plan → find out deformation tools/machines we have access to, come up with a test plan
Continue wheel tread investigation

a4tersig@uwaterloo.ca (Unlicensed) (Chassis)	Still debating extrusion VS CF	CAD both ideas for chassis, get opinions before review
amillsem@uwaterloo.ca (Wheel connections)	Feedback from Composites Canada! Constraints for adhesive and adhering techniques is temperature-dependent (aluminum expands and contracts more at extreme temperatures, compared to CF) The decision to bond aluminum on the inside VS outside should be based on what's easier for us Leaning towards bonding aluminum on the inside. Easier to make the OD precise vs the ID Recommended bond gap for ambient temperature is 1mm Glue beads to maintain minimum adhesion thickness Rough calculations for 32mm diameter Conclusion: seems to be okay! Supporting the entire rover will still be weaker than CC's weakest tube	CAD integration Verify wheel CAD
cchaikla@uwaterloo.ca	Finished Wheelez CAD
Emily Adam (Differential bar)	Motor selection, encoder selection	Send Asha information about motors and encoder CAD differential Order tubes, gearboxes, encoders Investigation tools that we have access to: 3-point bending test, load testing, impact test (abuse it until it breaks), drop test Read some rocker bogie papers
mapitzgr@uwaterloo.ca (Frame/structure)	Floating & fixed bearings investigation	CAD rocker-bogie structure, considering opportunities to integrated fixed-floating bearings
