The Sewer Snake, the reigning heavyweight champion in battle bots, is made by Team Plumbcrazy, run by a husband and wife. The six-wheel design prevents other battle bots from getting underneath the vehicle and flipping it over. The Sewer Snake is a lifter/flipper, which means it incapacitates opponents by flipping them and preventing them from moving. In the U.K., crushers that try to pulverize opponents, are more popular.

"We look at battle bots sort of as rock, paper scissors," said Matt Maxham of Team Plumbcrazy.
