Andrew T.

  • Worked on ->
  • Odrive pcb enclosure
  • Arm board
  • Finalizing Arm Motor Controller connecter layout and mounting 
    • single layout, all connectors come out perpendicular to board plane

Andrew Z.

  • Sorry I don’t think I’ll be able to make it tonight but I didn’t really do much other than handing over the STL files to Azum
  • Simplified version of arm
  • Meeting about E-box
    • Invited to e-box trello
    • check slack mail

Alaina

  • Working on: Hub attachment

Asha

  • Science CAD/drawings
  • Timeline plans
  • Science prototyping
  • Orders
  • Rough design for base station
    • Add to trello page for base station
  • Encoder mount changes for arm
    • Still need to select encoder(s) we plan on using
  • Science camera mount

Caleb

  • Motor verification and moving motors to ME/EE doc confirming science and gimbal motors to purchase
    • Waiting on emails
    • This saturday 3Pm meeting with tony.
  • Gimbal PCB layout seems good
  • Hex key prototyping
    • hex calcs & spring
    • Might not even need this ^
  • Motors
    • Arm (elbow, wrist, claw, shoulder) final check
      • prob all Pololu motors 
    • Do we have 12V rails anymore? Should we swap out the turntable motor (Lance says it’s not a big deal just run at 50% speed)
      • Lance: no more 12V rail, we can run the turntable off 24V, it's cheap
  • Gimbal
    • print it out 
  • Ask Aidan what he needs for PCB (dxf’s)

Tony

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

Odrive

  • Model new hall effect switch fixture blocks
  • Give wiring for pcb enclosure

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
