|We have reviewed all parts and have made the following decisions:
Winch (lego makes one or you can order one yourself)
Thin layer of plastic
Conveyor belt links
Extra Treads, motors, gears, lego bricks, and wheels
However, everything must be accounted for in your $50 budget, including
extra parts that you have yourself (just to keep things fair). You may
borrow something from another group but make sure it gets returned and
charge this to the account as well. This is part of working on a project
with a budget. Basically, we allowed everything that was safe.
We strongly discourage using more the 4 motors since the handyboard can
only drive 4 independent motors.
