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
