With the Überbots construction and RC kits, kids spend most of their time designing and building offenses and defenses and then testing their assumptions on the field of battle. If they are knocked down three times, they return to their lab and redesign to come back stronger. The more kids play, the more sophisticated their designs become. Dane Scarborough, inventor of Überbots and Überstix, told TDmonthly, “Build a boat and it floats or sails; build a UFO and it really flies; build a skyscraper and your ceiling may get in the way. More than one retailer told me that placing the order felt good because Überstix are designed to work with recycled items, including water bottles, Popsicle sticks, McDonald's straws, paperclips, etc. … This feature allows kids of all economic backgrounds to build big.” The kit builds two Überbots with 250 Überstix, two controllers and two flags. Each Überbot will operate on a different RC frequency, with up to six Überbots capable of battling simultaneously. The kit can also be purchased with rechargeable batteries.
