Action Items

@Austin Tailon Huang (Deactivated) 

  • test gripper?

  • update/solidify test plan for arm and test arm

  • finally going to test/print/design a cycloid prototype

  • try to calculate to see if A2 backdrives analytically

@Former user (Deleted) 

  • Clarified science requirements

    • Started planning/sketching out some possible designs for mounting sensors.

  • Continue work on science mechanism

    • Might need to redesign the whole thing (apparently the current one doesn't work very well)

  • ZED2 camera procurement (we're outta WEEF money )

  • Figure out how to add multiple sheets onto one drawing.

@Former user (Deleted) 

  • Created A5/A6→ End Effector transition part

  • Added to arm V1 assembly

  • Finish drawings for part

  • Machine part

  • Get in touch with Medina to find out what other parts need to be machined

  • Machine L6 back bracket

  • re-machine front bracket if time permits

@Ethan Cronier (Deactivated) 

  • Preliminary testing for end effector

  • footage for end effector sent to demtool

  • Port over more stuff to confluence

  • distribute tasks?

  • work on time line for next arm

  • plan plan plan

New Tasks

  • Weigh parts to check with CAD

  • figure out A4 sqeezing and backlash

    • have to prevent A3 backdriving first - temp fixture to block motion?

  • test fixture for A6 individually?

  • Current load for A5 is 11A, pretty high

  • test gimbal

    • need zed 2

    • test with another camera? zed 1?

  • Arduino board stuff needs to be programming

    • get current sensors working

    • get encoder data

    • position control

    • get IK working - mid September

    • test repeatability



  • get hard numbers

  • COMPARE PHYSICAL DESIGN WITH CALCULATED DESIGN

General Notes

  • lower amperage for the arm

  • A2, A3 is back-driving due to gravity
