2020-09-01 Meeting Minutes - General

Andrew T.

• 3d-printed frame designs for arm boards finished

• Found anderson connectors for odrive

• Odrive pcb enclosure

Andrew Z.

• Small finishing changes to simulation CAD model (excluding arm) -> how should I hand the files over to Azum?

  • Called w/ Asha, talked about rover actuation

• Start work on simplified version of arm

Alaina

• Working on: Hub attachment -> blocked by Tony

  • Rocker -> Bogie section

• Science camera mount

• Check Ansys?

  • Message Tony if it doesn't work

Asha

• Science CAD

  • Lid clearance, considering extending linear rail

• Machining thread on a lathe

• Wheel force jig

• Figure out laser cutting stuff with Tony

Caleb

• Torque hex multiple tooth design

• Started work on calculations

• Hex key calcs, maybe print prototypes

Tony

• Ordered drivetrain tire and magnets 

• Modified stator design, added hall effect sensors

• MOD-1 design FEA

• Remeasured hub motor for dimensions (found some errors during testing)

Drivetrain work

• Design Analysis of Wheel Assembly MOD-1

• Define manufacturing workflow for drivetrain

• Create a BOM for wheel assembly for cost analysis

• Define drivetrain constraints and requirements in system doc

• Finish reading unidirectional composite material properties, estimate structural member sizes

• Tire energy methods FBD

Gimbal

• Print Gimbal parts

Odrive

• See Odrive can run motor on back EMF

• OR (not preferred, I’m broke) Buy a “normal” BLDC with hall feedback, scope and test with odrive

Documentation / Support work

• Editing TQ meeting document so it’s readable for everyone

• Start new ordering sheet; add good slip-ring to ordering sheet

Misc work

• Set-up Solidworks PDM / SQL 2014

• Make a typical manufacturing tolerances table

Cole

• Figured out smart infill 

• Finalize e-box connector panel  

  • Meet w/ david → ??? → haven’t heard from him in a while

• Research what’s needed to use PC filaments with PRUSA I3

Emily

• Finished rocker hub design with variable angles

David 

• Redesigned bottom plate for science to have mount for PiCam

• Experimented with topological optimization and generative design for PiCam bracket mount

• Researched alternative materials for e-box

• Have meeting with Cole about e-box connectors

• Finalize layout for e-box components

• Re-design bottom plate for science to have mount for science

• Looking for more work (drivetrain/looking for something more technical) - hopefully something I can finish by September
