2020-07-14 Meeting Minutes - General

Andrew T.

• Initial CAD design for wheel hub ILM 115x25 variant

• Review wheel hub CAD and go over calculations needed

Alaina

• 6-Wheel CAD 

• 4-Wheel CAD

• Hub attachment 

• Science camera mount

• Welding research

Asha

• Welded joint strength research

• Science CAD fixes (elevator height etc)

Caleb

• Spaenaur fasteners found

• Looked into harmonic

• Science motors (checked motors over a bit)

• ANSYS installed

• Work out ideal motors with science

• Figure out if anything needs to be done for the gimbal for the electrical team (any resizing etc)

• New work

• Learning ANSYS

  • Go over licensing server stuff

• Learning IK

Tony

• Motor Disassembled and testing jig ready to go

• Hub motor weighed, measured for dimensions and changed CAD to reflect

• Odrive software installed 

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 encoder for Odrive

• 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

• Finalize e-box connector panel  

  • 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
