Andrew T.

  • Working on ->
  • New arm pcb integration design
    • Hand off to Emily for layout when done
  • Connector hub for TQ motor configuration

Andrew Z.

  • Started on very simplified version of current CAD model
  • Finished simple version of drivetrain subassembly that’s attached to the wheels (not sure if there’s a name for it)
  • Work on frame
  • Work on arm

Alaina

  • Hub attachment 
  • Science camera mount
  • 4-Wheel CAD
  • Welding document 

Asha

  • Drivetrain falling math
  • Beam bending reading
  • Science CAD fixes (elevator height etc)
  • Drivetrain material properties etc

Caleb

  • Gimbal - added metal bearings (made hole bigger & stuck needle bearings instead of printed ones)
  • Gimbal - shortened it (more compact roll/pitch)
  • Gimbal - Epoxy calcs (epoxy works)
  • Science motors - confirmed eligible motors 
  • Briefed on claw ideas for hex key 
  • Met with Tony for ANSYS
  • Possible designs / ideas for claw hex key
  • Haven’t verified ansys license yet
    • Figure out after meeting

Tony

  • Motor test bench design finished
  • Firmware flashed

Drivetrain work

  • Define drivetrain constraints and requirements in system doc
  • Finish reading unidirectional composite material properties, estimate structural member sizes
  • Design a 3-D printed motor housing
  • Finish alternate design using ILM 115X25
  • Source and purchase appropriate power resistor for Odrive
  • Flash Odrive firmware st-link on disco board; also probably need to configure based on the encoder being used
  • Tire energy methods FBD

Claw re-work

  • Allen key attachment friction-torque calculation
  • Finish flexure design

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

  • E-box connector panel
  • 3D-Printing research
  • Figuring out topology optimization “smart infill”
  • Finalize e-box connector panel  
    • Meet w/ david → Waiting on kyle from electrical? 
  • 3D-Printing
    • Print & test some parts

Emily

  • Laid out groundwork for stress/strain analysis for CF members
  • Finalize science PCB plan & put into CAD
  • Finalize stress/strain research once I receive values from Asha

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
