Below is the list of materials needed to build this starter bot. Please note that we have included hyperlinks in the “PART NAME” column. These are suggested links for purchase, but they are merely suggestions. If you can find better/cheaper sources to purchase the same materials, feel free to do so.
Materials with “N/A” in the “COST PER” column indicate that the suggested purchasing link is for a pack of that hardware (i.e. no cost for QTY 1).
