Combat Zone

BUILD REPORT: Tanto

For the last 16 years, I have been building and competing in robot combat. You name it, I’ve probably built it — from walkers to brick bots to full power flippers to hydraulic crushers in almost all weight divisions.


THEN and NOW: A Decade Later With Richard Stuplich

Richard Stuplich first came to the public’s attention in the final two seasons of BattleBots. His super heavyweight, New Cruelty, was eight wheels and 220 pounds of rock solid battering ram.


Orangutan Drives Fleaweight

One of the challenges when designing a Fleaweight (150 g) robot is finding lightweight components that allow you to squeeze the most out of the limited weight allowance.


PRODUCT REVIEW: Botbitz 30A ESCs

The Banebots BB-12-45 was for many years the most commonly used speed controller in the 12 lb Hobbyweight class of combat robot.
