    Progress Report
    • cut towers to length
    • cut arms to length
    Action Items
    • attach bushings to arms + towers (waiting for bushings)
    • cut plate for motor mount
    • work on finalizing the design for claw

    Progress depends on getting the specific parts we need - sprockets, chain, drawer slides, etc. Sarah has been working on the claw design, but won't be able to come in until Friday - if no progress can be done for the arm/towers (bc we haven't gotten certain parts), will be working on finalizing the claw design + or helping build chassis.
