Update & Action Items

MemberUpdateAction Items

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
