Drivetrain work

  • Define drivetrain constraints and requirements in system doc
  • Finish reading unidirectional composite material properties, estimate structural member sizes

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

    • Meet w/ david → Waiting on kyle from electrical? 
  • 3D-Printing
    • Try out “smart infill” w/ topology optimization
    • Print & test some parts

Emily

  • Research on welding
  • Updated rocker hub with revisions & designed for welding
    • Modify tube angles so that it reflects drivetrain frames
  • Figure out what type of welder we have access to
  • Science PCB integration once PCB approved
  • More tasks?

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
