Two motors need two single-motor purchases. Two hubs need one two-hub pack. Two wheels need one pair.
PHASED SHOPPING AND QUANTITIES
Amazon is preferred. Seeed Studio and Pololu are the two direct-store alternatives for exact parts not verified on Amazon. Order only after inventory and the relevant design review; a stock listing does not release a build.
Two motors need two single-motor purchases. Two hubs need one two-hub pack. Two wheels need one pair.
A caliper or hex tool shown in several steps is the same tool. Check what is owned or included before buying another.
Fastener lengths, harness contacts and full filament demand depend on measurements. TBD is not zero and not a guessed allowance.
Unknown stock receives no deduction in the displayed upper-bound counts. Do not sum step-use quantities. Alternative audio paths and deferred expansion are excluded from the baseline.
