BioHazard, one of the stars of BattleBots, has been busy pumping out progeny. BattleKits, which come in multiple weight classes and sizes, are ready-made competition robots containing drive trains and controller mounting points making them a great jumping off point for those wishing to create a death-dealing super cyborg. Each is based on BioHazard's award-winning design. [Thanks, Jackson!]
The kits, unfortunately, do not include weapons or armors, so you'll have to wire up that Taser/shotgun combo up yourself. Prices range from $499 for the BioHazard like lightweight kit to $899 for the heavy duty chassis.
