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
