MemberUpdateAction Items

Andrew

  • Revising pcb integration onto arm design

Alaina

  • Working on 6-Wheel CAD
  • Science chain attachment 
  • 4-Wheel CAD
  • Figure out how to attach hub motor/connector hub design (?)

Asha

  • Screenshots and reading of wheel doc
  • Motor calculations
  • Cheese for science elevator (once tensioner is on)

Caleb

  • Gimbal redesign done
  • N/A (looking for new things)
  • Touch up aesthetics on gimbal
  • Find better screws on spaenaur (currently 2 screws can’t be found, M2 and 1-64, will keep looking)

Tony

  • Received new motors, began disassembly

Drivetrain work

  • Define drivetrain constraints and requirements in system doc
  • Finish reading unidirectional composite material properties, estimate structural member sizes
  • Disassemble hub motor for weighing
  • Setup Linux dual boot to run O-drive
  • Design set-up for testing motor torque to current draw
  • Design a 3-D printed motor housing
  • Finish alternate design using ILM 115X25

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
  • Look into harmonic / strain-wave gear drive for future season / arm designs
  • Look into 3-D printing as alternative for machining (variating print infill density to stress using FEA)
    • Send links to cole
  • Make a typical manufacturing tolerances table

Cole

  • E-box lid design 
    • Considered different snap lock designs 
  • Research rivnuts
  • E-box connector panel
  • Finalize e-box connector panel  
    • Meet w/ david 

Emily


  • Thoughts on welding?
  • Science PCB integration → waiting on PCB shapes to be finalized

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
