The parts that we ordered finally arrived today, greatly increasing the
resources that we have at our disposal and allowing us to build bigger
and better robots. These new parts will be stronger that the parts we
currently are using and will provide us with better performance.

Silly String
Nik and Pierce
troubleshooted our lift system and decided to scrap the string being
wound on the side, as it would not wind correctly and started to destroy
the string. Instead, the string was moved to an axle beneath the arm
that is turned by a gear attached to a motor. This arrangement prevents
the string from stretching when the arm is lowered- another problem we
encountered- and provides more torque for raising the lift, making it a
much better solution.
Feeling Rather Spoolish
Unlike the last spool – which was mounted on the side – this one goes between the two bars in the arm, meaning that it's a more direct route for the string than before. In addition, the string uses the arm's axle as a pivot, meaning it will always be the correct length regardless of what angle the arm is at. Pretty nifty, I think.
