  • Sent drawing of arm hub block
  • Got some parts of the arm revision printed (s/o to Ari)

Arm

  • Export manufacturing files for arm parts needing laser cutting (dxfs), figure out who will make them.
  • Order off of McMaster-carr based on BOM
  • Order 24V Elbow motor 1 (Tony needs to review costs)
  • Order lazy susan
  • Come up with arm system diagram
  • Get reimbursed!

Main Assembly

Daniel

  • Learned about SolidWorks Sheet Metal
  • Continue to work on battery cage redesign

Austin Huang

  • Finished preliminary design for encoder mount on shaft w/ test CAD
  • Got mounting plates measured (thanks Medina!)
  • Get feedback on first design iteration for claw
  • Go through measurement data to ensure printed base plates are within spec
  • Fit test base plates with screws

Jasmine Milan


  • Import PDB rev 2 and CAN breakout board rev2 into assy 
  • Strain Relief for antenna cords
  • Add fasteners (change holes to accommodate)
  • Add hole on rear panel for battery connector - double check PDB alignment so that PDB-battery connector is oriented to be close to rear panel battery hole. 
  • Create performance configuration of E-box PCBs

Ethan

  • Sheet metal parts sketched
  • Final assembly when fasteners come in (base station)
  • Resketch antenna connections (draw.io)
