2020-09-08 Meeting Minutes - General

Andrew T.

• Worked on ->

• Odrive pcb enclosure

  • Tony needs to actually send the wire out this time

• Arm board

  • Figure out with Lance and Kyle

Andrew Z.

• Simplified version of arm

• Send STL files to Azum N via slack.

• Meeting about E-box

Alaina

• Working on: Hub attachment

• Science camera mount

Asha

• Science CAD

• Science prototyping

• Machining thread on a lathe

• Figure out laser cutting stuff with Tony

Caleb

• Hex prototypes/some calcs finished

  • layers adding unwanted friction >:(

  • Friction clutch not feasible (plastic creep/heat deformation & not enough surface area)

• Gimbal PCB connector placement (except power)

• Slight changes to gimbal PCB (added standoffs)

• Confirmed Assun motors AM-CL3570GA/B series still exists (torque-current curves added to documentation)

• Hex key - print prototypes

  • finish calculations (verify FBD)

  • Figure out spring

• Motors

  • Verify science motors with Asha/Lance

  • Finalize Linear actuator

• Gimbal PCB connector placement (need power from EE and will create the DXF files for Aidan once I get that)

  • (Lance currently in process of getting that)

• Clean up motor datasheet (some unneeded motor data and need to find stall current for some)

Tony

• Drivetrain tire arrived, measure dimensions and weighed 

Drivetrain work

• Design Analysis of Wheel Assembly MOD-1

• Define manufacturing workflow for drivetrain

• Create a BOM for wheel assembly for cost analysis

• Define drivetrain constraints and requirements in system doc

• Finish reading unidirectional composite material properties, estimate structural member sizes

• Tire energy methods FBD

• Wheel force jig

Gimbal

• Print Gimbal parts

Odrive

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

• Arrange time for E-box meeting

Cole

• Figured out smart infill 

• Finalize e-box connector panel  

  • Meet w/ david → ??? → haven’t heard from him in a while

• Research what’s needed to use PC filaments with PRUSA I3

Emily

• Finished rocker hub design with variable angles

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
